Basically I followed my plan (outlined below) and it all worked well -- I've always been impressed with Veritas, but this was just obsurdly simple, and worked well. I'm really impressed that Veritas managed to put the mirror disk into a devalias in the OBP, I never even had to learn the full device name of the disk...
Once again, the sunmanagers group comes through....
later all!!
<topher's original message>
scenario:
Solaris 8 root disk is mirrored via Veritas Volume Manager 3.1.1(/ /usr /var all mirrored)
root disk and mirror exist in a SUN StorEDGE MultiPack (so no hot swapping)
mirror disk is named rootdisk2
devalias is defined in OBP for vx-rootdisk2
primary root disk has failed -- currently running on the mirror
plan:
shut down the system to OBM -- run 'boot vx-rootdisk2' to boot off of mirror
remove the associate between the failing device and it's disk using "Remove a disk for replacement" function of vxdiskadm
shut down the system (again) and replace the failed disk
boot vx-rootdisk2 again
use vxdiskadm "Replace a failed or removed disk" menu item to rebuild the primary disk
question:
does the plan look good? Has anyone done this before with fewer reboots? Should I move the 'mirrored' disk to the primary slot to boot, then just re-mirror it?
Any 'gotchas', 'thoughts', or 'considers' would be appreciated.
Please don't assume anything -- if it's not listed, I'm not planning to be doing it. If it's not listed, I likely haven't done it in the past....
