Sun - Week Seventeen & week with Faye

I only spent one and a half days in work this week!  Monday was spent doing some work, while Tuesday morning was spent tying up loose ends and passing other people ongoing work.

I then travelled up to Aberystwyth.  I was delayed in getting to Wolverhampton by 20 minutes, so missed the train to Aber.  A two hour wait sitting by a vending machine so I could charge my phone and I was back on the train, arriving in Aber for about 11:40pm.  I met Mike and we went off to Downies where I met up with Faye, Ben and Lauren.

Wednesday marked one year for me and Faye, we didn;t do a great deal, we went to Morrisons for ice cream (Ben & Jerries only £1.80), and in the evening we went to the tapas restaurant just up the road from Downies.  It’s a lovely place, and the food is great.  We had some tapas (cured ham, chicken salad, meatballs, beef croquets and warm vegetables), and the some paella.

Thursday was spent doing not a lot, we rearranged Faye’s room, and went up to Mike’s in the evening to for TV, pizza and drinks :D Oh, and I did part of the CS101 lecture :D  I’ve blogged about it here: clicky

Friday we ran around looking for Halloween gear, then rushed up to Mike’s in the evening to get ready.  We then spent the evening at Rockey Horror at the union (Facebook photos are up I’m sorry to say).

Saturday was a quiet day.  We walked up the hill to get Faye’s car, well, we had to clean it first as someone had egged and floured it :(  After that the day was spent relaxing.

Sunday was, again, not spent doing a tonne.

Monday me and Faye spent the day together, wandering out into town and having a womble around Aber.  I left Aber at 5:30, only to get back to my Camberley house at 12:30.

It was a great week, I loved spending all that time with Faye :)

OpenSolaris & CS101

On Thursday 30th October, I attended the CS101 lecture in Aber uni.  I was there to give a brief talk about OpenSolaris, focusing on aspects like Zones, DTrace and ZFS.  I think it went OK, possibly pitched it a tad too high, and I missed out tonnes of stuff I wanted to put in, like the copy on write feature of ZFS…

If anyone attended that lecture and is reading this, please feel free email me any questions you might have about OpenSolaris.  If I can’t answer them, I can find an answer :)

Sun - Week Sixteen

OK, writing this from the future, I can’t remember the details of this week…

The main forcus for this week was playing with a blade chassis, and a load of blade servers.  I was playing with a mix of X64 and SPARC systems, I was amazed that you could mix the two in an enclosed unit.  I’m still unsure why you would choose a blade over a 1U unit…

I had a hard time because I needed to liaison with several owners of blades in the chassis to get them moved to other chassis.  After this was complete it was just a case of installing new blades and upgrading some firmware.  Mick (the engineer who I was doing the work for) then installed some new blades which added storage to the blade next to them.

Interesting stuff…But I think I’ll try to leave them alone…

Sun - Week Fifteen

Week Fifteen, subtitled:

The small things

Monday morning started with the subtitle. I saw a pigeon fall from the sky, frantically flapping it’s wings causing some leaves to scatter, it made me smile. This week I shall try to look for the small things that make me smile, and report them here with the rest of my news. The morning brought a job which I have already had too much experience with, unpacking boxes which hold products…Leekes brought me much experience in how to open a card board box, and take out products, it’s a boring task, but this morning the mundanety was lifted with the fact these were new products, and there I have to stop and tell you no more :P My lunch break ended with me setting up another monitor….A flat screen for extra windows and the like, however, I have retained my ten workspaces for various things…8 of which are still as full as ever… The afternoon was spent working on some console problems with a machine in France, hunting around GMP02 for a T3 storage array and a couple of other little tasks, as well as the weekly meeting about what happened what is happening and what is going to happen…

Tuesday started with setting up a 280r with a D2 array, these were customer systems which were to be worked on. The small thing for today, is that with swivly chairs (the ones with wheels) you can scoot around the lab quite happily with very little effort, it makes every job fun :D Late morning and the afternoon was spent documenting the partitioning and mirroring of disks at jumpstart level. I’m also testing out the steps using X86, if I remember, I shall post back to say whether it worked or not….

Wednesday saw me running around and cleaning up my queue of tickets. I cleared about four away which was good, still got a number left. I spent the afternoon troubleshooting why a customer system (a V240r) wouldn’t net boot, as well as looking at some documentation, both stuff I needed to update, and other stuff I needed to understand and implement. The small thing for Wednesday almost didn’t happen, but then, waiting for the bus, the wind picked up and swirled some leaves about in a kind of whirl wind fashion…

Thursday was the start of a two day TOI (Transfer Of Information) on X64 machines. We have so far looked at what CPU’s our servers have. Then went into details about the interconnections of CPU’s/memory/north bridges. We learned how HyperTransport worked in AMD systems, and how Intel’s FSB was being replaced with QuickPath. We moved onto looking how the BIOS is loaded in such a legacy fashion, and builds up to booting the whole machine…Then the last thing before lunch was looking at how Service Processors work, how they connect to the outside world, as well as to the host itself. After lunch we looked mainly at RAID and how the chips we use for hardware RAID don’t change much from revision to revision, so we can keep similar drivers and maintain them over several platforms easily. After the course I looked at my 880 and applied some patches, I also booked out a T5440 which I am going to use to test some features of ZFS. Hehe, my small thing for today was the fact that I half followed, half made up a recipe for lasagna, and it turned out pretty good! :D

Friday went slowly, with us looking at the theory behind IPMI tool and then some IPMI in action.

Friday night is what I want to blog about now…Bill Bailey! Me and Faye went to London to see Bill in his guide to the orchestra! It was brilliant, after leaving work early and driving through London to the Royal Albert Hall, we sat there waiting for Bill to come on stage. He finally entered and began his guide, from the 1970’s villain themes played by the trombone, to the interesting fact that all oboe players love the BeeGees…. My little thing of the day, came from the ride home, when I saw a sign for yawbus, then realised that it was actually a sign saying ‘Subway’…Made me smile…

Sun - Week Fourteen

Monday starts off with me looking into this jumpstart image. It turns out to be really easy! All I needed to do was to find the Solaris 10 Update 4 image, this had a file called setup_install_server (or similar), I just used this executable file to install the image to another directory. After this it was a case of using the patchadd command:

patchadd -C

And this installed that patch onto the image for installation at install time! A bit clever or what!? The afternoon was spent looking at mirroring a machine at install over jumpstart…I didn’t get it to work :( But I shall keep trying!

Tuesday was spent looking into why I couldn’t jumpstart an X86 box with Solaris 9 update 8…I tried various machines in our lab, as well as other machines around the world, some labs don’t even have an image that old! The V65s and the LX50s that I tried either didn’t have rpower configured, or were just being a pain. Alas, I didn’t finish the task by the end of the day :(

Wednesday morning was partially spent on yesterdays problem, but I was also asked to help set up an X2200. The afternoon was spent trying to install *Windows* onto that server :| It felt wrong and awful…

Thursday starts with me continuing the install of Windows….Apparently it doesn’t know how to do sata raid :roll: Oh well, out comes the floopy disk so I can load drivers on! The afternoon was spent doing some tickets. One involved moving some firmware versions form one place to another and reorganising some of firmware files. I also got the chance to look at my 880, which I’m using to try and practice LiveUpgrades. I’m currently learning about the JumpStart profiles..

.

Friday morning I spent installing the drivers for the Windows box that didn”t understand fibre cards. I then helped David and James set up some storage for the box. I then went over to GMP02 to receive a package, this contained some fan trays for an 880 in GMP02 , so I went upstairs to fix it. I forgot to check the console line, so shut the server down while the engineer was doing work on it…I apologised and quickly went to lunch, After a slightly elongated lunch I received another email from the engineer who was very good about the situation :) I then spent the afternoon playing with custom Jumpstarts with my 880. At the moment it’s complaining about unexpected allocated inodes….Here is my profile, it’s most probably wrong:

install_type initial_install system_type standalone partitioning explicit metadb c1t0d0s7 size 8192 count 3 metadb c1t1d0s7 size 8192 count 3 filesys mirror:d0 c1t0d0s0 c1t1d0s0 10240 / filesys mirror:d0 c1t0d0s3 c1t1d0s3 10240 /var filesys mirror:d0 c1t0d0s4 c1t1d0s4 10240 /opt filesys mirror:d0 c1t0d0s5 c1t1d0s5 10240 /mnt filesys mirror:d0 c1t0d0s6 c1t1d0s6 10240 /tmp filesys c1t0d0s1 free swap isa_bits 64 boot_device any update cluster SUNWCall

Hopefully I can get something out of it :)

Looking at this doc, it seems this should work: install_type initial_install system_type standalone partitioning explicit metadb c1t0d0s7 size 8192 count 3 metadb c1t1d0s7 size 8192 count 3 filesys mirror c1t0d0s0 c1t1d0s0 10240 / filesys mirror c1t0d0s3 c1t1d0s3 10240 /var filesys mirror c1t0d0s4 c1t1d0s4 10240 /opt filesys mirror c1t0d0s5 c1t1d0s5 10240 /mnt filesys mirror c1t0d0s6 c1t1d0s6 10240 /tmp filesys c1t0d0s1 free swap isa_bits 64 boot_device any update cluster SUNWCall

Seems to work!

After this it seems to go into the installation.

Also, an alarm went off right next to where we work, so most of us had ear defenders on…

Sun - Week Thirteen

Unlucky for some, will it be for me? As you possibly guess, I write parts of entries throughout the week and publish on Fridays, so at the time of writing, I have no idea if it’s going to be a good or bad week, it’s 11:50, Monday morning :P

So Monday starts off with me cycling in, sitting down to breakfast then being interrupted because a fibre cable won’t come out of it’s socket. I went down to the lab where me and the engineer pulled it out and I took the cable upstairs to bin (must do that sometime actually). While getting ready for the day Clive King popped into the office! Not sure why he’s here, but he was checking out some of the M series machines…I’m pitted against the same problems that were pestering me last week, as well as a problem with an Ultra 10 that is pingable, but won’t net boot. I made a new group for a multihead SunRay :D utmhadm myName -d 2x1 -p 0123456789ab -l 0123456789ab,cdef01234567 I spent the afternoon fixing an Ultra 10, the problem was about lab tool ‘js_config’ not being properly configured for the machine. I also had an Ultra 80 to look at, it didn’t want to boot, so after rearranging the CPUs, I concluded it was a duff system board, so another one of them is on order… As I cycled out of the campus, a squirrel, obviously daring death, leaped out in front of me, it’s tail inches away from my front wheel!

I woke up this morning and went down to the shower finding the kitchen in a mess. While making lunch I found that my tuna had been eaten and that the foil I had bought had been all screwed up. Coupled with the fact that I had forgotten my Sun badge today, I wasn’t off to a good start. At 10:30 I had a meeting with Paul about our console server (enotty), it is still on Solaris 10, the original release! I’m about to do some testing on an 880 so I can simulate a LiveUpgrade and get to know any pitfalls I might encounter.

Wednesday morning started with me replacing the Ultra 80 system board,only to find that it was faulty, so had to replace it with the old system board, send the new one back and request a new board. The system was very different to a normal ‘PC’. The RAM was really weird, a little switch rocked left or right to release the DIMMS, the CPUs have a couple of handles on (like DIMM slots), when pulled they unlock the CPU and slide out. The new system board wasn’t powering up. I whittled this down to the bottom slot not wanting to be populated with a CPU. Alas, after taking the bottom CPU out, there was still no output on the screen. During the afternoon I tried to get to grips with the LiveUpgrade stuff, but I was asked to take up another task which involved trying to get a Minnow to work. I’ve got no idea what I’m doing, everybody seems to think I do, everyone else seems to know a little more than I do too…Didn’t get it to work, will leave until tomorrow.

Well, I think this is an unlucky week. I was woken up last night by house mates coming in at 2am, with some girl that just screeched, she ended up sleeping with one of them…They made a racket until 4am, then I finally got some sleep… The morning at work hasn’t been much better, I’ve been working with this Minnow still, I think I’m trying to trouble shoot problems with an HBA, as now I’m using a unipack and still getting errors….Just swapped the SCSI cable from the upper port on the HBA, to the lower port, and it seems to recognise the disks now! Just got to wait and see whether the engineer is happy now :P Lunch seems in order… The afternoon was spent trying to get some last few things tied up before home time! This included more work on that blasted Ultra 80! Still not fixed :( After work I met up with some of the guys who work on the floor below us, me and Tom went to their house just over the M3 for a few games of cards and some pizza, was a great night :D

Friday starts with estale, one of the Sun Ray servers, crashing…Still not sure why, but suffice to say, it dragged my session down with it…Ho hum, it’s been a very busy morning due to people trying to solve this, and people submitting more tickets than usual…I’m sure they heard we were having problems and thought they’d give us a challenge! I’ve powercycled a machine from the SP, removed a booking and tried to get a switch to work. The switch wouldn’t ping or give us a console connection, so I’ve passed it over to Tom who might be able to do a little bit more! Jobs for this afternoon include making a custom jumpstart image…Oh, I also booked tickets for me and Faye to go see Bill Bailey in a couple of weeks time :D Clicky Perhaps more importantly; we’re going to be in the Royal Albert Hall :D The afternoon has been quite full. I finally fixed that problem with the T2000 as a node, I just took out all the cards, reinserted them and voila! It worked! I have also been working on getting the customer jumpstart image to work, I’ve not advanced much…But hopefully I’ll get it done by the end of Monday. I’ve also been postbooking some machines, this has so far just been making sure hosts are alive, then jumpstarting them with Solaris 10 Update 4. Early next week I shall look at making sure they don’t have extra cards or network stuff attached to them.

Sun - Week Twelve

Monday started slowly. I cycled in and not much happened in the morning. By the afternoon I had inherited a couple of tickets which I started work on after lunch. Immediately after lunch we had the weekly staff meeting, then I got cracking on some tickets…One system wasn’t turned on, so I turned it on (very taxing) and I started to look at Liam’s ticket about remaining SAN switched.

Tuesday was really busy. I finally received the RSC for the 280r that I needed. I installed that then headed over to GMP02 to look at a cluster. I had to repair the box after James had maliciously ripped it to shreds…Or rather he had broken a switch that makes the system power off when the lid is removed. I replaced said switch and some gubbins to do with that, then popped the machine back together. Upon completion, it was lunch time :D After lunch I talked to the guy who has booked the cluster system, but didn’t get any time to continue work with it. I had to configure the RSC from the 280r platform, which was weird, and after much fiddling and replacing of cables, I finally got it to work. I have also had to explain how to jumpstart a system to an engineer after directing him to the relevant documentation several times. That’s taken a large part of the the afternoon!

Wednesday was taken up completely by the cluster I’ve inherited from James. I don’t know what I’m doing, the engineer doesn’t know what is supposed to happen either. The two nodes didn’t boot in the morning, and I spent the morning locating firmware images and working out how I could up an FTP service so I could update the firmware on node b. The afternoon was spent trying to set up the FTP server, which David Cole helped with, and the finally upgraded the firmware. Then there was the problems with node a. It just wouldn’t get to OBP, it was really annoying. I reinstalled the firmware, but to no avail. It was home time before I got it working, so more fun on Thursday….

As promised, more T2000 fun on Thursday. I ran the max verbosity, max diagnostic levels of POST, with no clue as to why this system won’t boot. While I was letting the POST run, I tidied and rearranged my desk:

The afternoon was spent trying to troubleshoot further, to no avail :(

Friday morning was spent on getting this system to work. In downgraded the firmware, upgraded the firmware and a number of other things, but nothing has happened :( It is currently mid afternoon and I have a splitting headache. I can’t wait for hometime so I can see my Faye :D And Aled is coming down too!

Sun - Week Eleven

After a wonderful weekend with Faye, Monday started off with getting up early for a call with the APAC guys (Singapore and Australia), we were talking about new development life cycles - something that bores me at the best of times, and today was no exception. We do need to re-evaluate the way we fix bugs and release new versions of our lab tools though. The rest of Monday was fairly quiet, with a second meeting in the afternoon.

Tuesday was much the same as Monday…We have a work experience lad in this week, so I took him down to the lab and tidied away loads of hard drives and PCI cards. After lunch we finished off what we hadn’t done and I took him around and showed him the insides of a range of servers we had. He seemed pretty interested, I just hope I didn’t melt his brain :?

Wednesday I finally finished off the new starters document! I’ve been working on and off on it for weeks! I finally printed it out and scanned through it, then James looked through it and pointed out one or two mistakes which I fixed. Late morning and the afternoon was filled with the moving of hard drives. We are getting rid of the present shelves and replacing them with new ones, hard drives are blinking heavy!!! And there was more than a few there!

Thursday morning went slowly, with an action on a ticket requiring me to order a new Remote Service Controller. In the afternoon I had a meeting with Paul, James and Hans to talk about a 12K in Florida. I then logged on and started to investigate how it was configured.

Friday was spent on a couple of things, mainly trying to figure out what was what with this 12K still… Last thing I did was spend some time talking to a Yankie who was quite rude over the phone. He wanted to have some things pulled out of a server, like PSUs and Fans…

SUNWlibsexy

I’m just updating packages on my OpenSolaris installation, and I glanced at the screen only to find a package called “SUNWlibsexy” sitting bang in the middle of the update screen. After a quick Google, I found this: > Name: SUNWlibsexy License: Other Group: System/Libraries Version: 0.1.11 Summary: libsexy is a collection of GTK+ widgets that extend the functionality of such standard widget. From here: clicky

Just one more thing in computer science which is…Interesting…

Sun - Week Ten

So this week I’ve been on my 15k/25k maintenance course. It’s was very boring. It was basically the serengeti training all over again.

It’s basically a big box with up to 18 systems boards in. Each system board has up to 4 CPUs and 32 sticks of RAM. These system boards can be joined together to create ‘domains’, these domains can run instances of Solaris, so you effectively get one system spread over several boards…You can even add and remove system boards while a domain is running!

It’s a remarkable piece of kit…But it was pretty boring to learn…
