SP/2 Changelog

I started this after I started to change things. Oops. I occasionally remember things that I've done and record it in the A long time ago section.

Mon May 20 16:07:58 CDT 1996

• Install FixDist an IBM utility for installing PTFs.

Fri May 17 11:58:39 CDT 1996

• Create a raw logical volume, disk2, on hdisk2. I created the device writable by group paradise device as /io/rdisk2.

Thu May 16 11:45:59 CDT 1996

• Cleanup /tmp on the nodes.
• Increase size of /var to 8MB; the previous 4MB was too close for comfort with 99% to 100% utilization.
• Reseat the SCSI and Switch interface cards in sp2-03. The boards were loose. This fixed the switch problem, but not the SCSI problems. It may be time to call IBM about this loose board problem.

Wed May 15 15:16:06 CDT 1996

• Power-cycle sp2-03 so its outboard disks will configure. That didn't work.

Disk Shuffle

• Remove the /home.old filesystem.
• Remove the jetty filesystem and logical volume
• Remove the beach logical volume
• Remove the miscvg volume group (hdisk1 was miscvg)
• Attach hdisk1 to rootvg.
• Add /local, a 1G filesystem.

Thu Mar 21 13:42:33 CST 1996

• sp2-16 has problems with its microchannel bus. Either the bus or the cards in it are loose. Both the SCSI and the Switch cards are loose, and they wouldn't configure. I wiggled the cards from the backside to reseat them. This may explain the earlier problems with this node.
• Todo: Call IBM to fix the microchannel bus.
• Fetch and install monitor, an AIX top and systat equivalent. It's installed in /usr/local/bin/monitor.
• I configured the quantum at SCSI address 4 on the external bus, hdisk4, as a JFS filesystem. The volume group for the drive is vg4. The filesystem is mounted as /shore/disk4

Fri Feb 9 13:09:50 CST 1996

• I power-cycled sp2-16. It was not reachable from the (ether)net.
• I rebooted a bunch of nodes. Cron had run wild on them. Interestingly, it didn't run while on sp2-01, where amd had screwed up.

Mon Jan 29 14:03:40 CST 1996

• Tim installs afs-3.4a on the CW. This must be done before the AFS servers can be upgraded.

Sat Dec 30 20:32:58 CST 1996

• Debug switch problems. The switch was turned off, and needed to be restarted. I think that rebooting the -01 node disabled it.
• Debug automounter problems on nodes -01 and -04. The sp2-cw:/home filesystem is mounted, but the link from /u to the mountpoint was missing.

Fri Dec 29 20:55:16 CST 1995

• I changed /etc/environment on the nodes to make Central Standard Time the system timezone.

Thu Dec 28 14:44:08 CST 1995

• Change karthik's shell to /usr/local/bin/tcsh.
• Add /usr/local/bin/tcsh to /etc/security/login.cfg on CW and nodes.
• Distribute karthik's version of tcsh in /usr/local/bin.
• Create /usr/local hierarchy on all nodes.

Wed Dec 20 12:20:15 CST 1995

• Karthik discovered bunches of crons on some of the nodes. I suspect they may be hung in nfs-mounts, but I'm not sure (no evidence). I rebooted all nodes as an expedient measure.

Fri Dec 15 16:30:16 CST 1995

• The jfs filesystem /dev/jetty is mounted as /shore/logs.
• The raw filesystem /dev/beach has a symbolic link from /shore/volumes/beach.
• I created a /shore directory structure on all the nodes. This contains logs and volumes subdirectories, which will contain links or mounted filesystems as approriate.
• Created a jfs filesystem, on miscvg, /dev/jetty on all the nodes. This filesystem is used for shore logs.
• I created a raw filesystem on miscvg, /dev/beach, on all the nodes. This partition has a 1 gigabyte, and is for the use of the paradise group. The raw device is group+rw paradise.
• Created a volume group miscvg on all the nodes, which contains hdisk1.

A long time ago, in a galaxy far, far away

• I changed /etc/environment on the CW to make Central Standard Time the system timezone.
• On all the nodes, I renamed the /home filesystem to /home.old. /home is now a link to /u. This allows the filesystem namespace on the nodes to be the same as that on the CW (/u and /home identical). I needed to do this to allow poe to work.
• I created a new /home filesystem on the CW, using space from hdisk1. The space from Hdisk1 is in uwvg.
• With help from tim I installed the AFS client software on the CW. All users are now authenticated through AFS.
