So, this is mainly just to sync my tech posts from WordPress. However, FB really is not designed for retrospective / reference. It is all about ephemeral marketing. Also, better WP plugins have occurred since this was set up. Either way, livejournal posts show up in Google, and FB posts are hard to find.

PROBLEM: On some migrates, we found the rpdomain would not stay running on one node. The cluster was up, and SEEMED to operate normally, but errpt got CONFIGRM stop/start messages every minute. lsrpdomain would show Offline, or "Pending online". lsrpnode would show: 2610-412 A Resource Manager terminated while attempting to enumerate resources for this command. 2610-408 Resource selection could not be performed.

Hitachi disks, clmigcheck always says there are no matching disks. This may be due to spaces in udid, or other problems with the awk line in list_common_free_disks The easiest fix is to A) Verify you have absolutely picked the right disk. Set a PVID and remove/readd it to make sure. B) comment out the "mv" line for the RESULT files.

0516-1980 /usr/sbin/extendvg: Block size of all disks in the volume group must be the same. Cannot mix disks with different block sizes. SAN LUNs are 512b LBA. Internal disks are whatever are presented. AIX wants 512b, and iSeries wants 528. AIX requires SSDs to be presented through a RAID controller, as a RAID device. This can be a single disk RAID0, but it has to be pdisk to hdisk conversion. [ 38 more words. ]

Marek Wołynko has discontinued and removed the wmarow iops calculator. Archive.org still has this. Just to be safe, I downloaded that and saved it for my own use: http://omnitech.net/iops/
