unable to remove disk after migratepv

[shane2]

Last night I started a migratepv hdisk93 to hdisk10. Over night, my session ended and I don't know for sure if the migratepv command was successful. I assume it was because hdisk10 is full, hdisk93 has nothing on yet. Also reducevg was successful in reoving hdisk93. But when I try rmdev -dl hdisk93, it fails saying the device is busy. This is on AIX 6100-05. lsvg -M shows; hdisk 93:1-618. Any sugestions of how to remove this disk?

Just off the top, of my slightly dazed and confused, head...

Check for monitoring software that might be holding the disk open / busy
Check things like migratepv are not showing in the ps -ef output
Use fuser or lsof to check what might be using /dev/hdisk93
If in doubt then it's probably a power out - reboot - to free it up...


HTH ;0)

Thanks for repling Duke,I tried all those things, except the reboot. I was afraid it would come to that. The reason for the migrate was moving off an old san. Ths was weird and I still don't really know why it worked, but I migrated back to the orignal disk and removed the disk I migrated to in the first place. Then I requested a new disk and migrated to that disk and then I could remove the disk that was busy. I ran the migrate command from Cron so losing my vpn connection would not effect the command. Caulk that one up.

sometime nmon process running with -d can lock the disk (even if not assigned to any vg). if so, stop nmon and try again.

also, try lsof - you should see nmon locking disk if this is the case.
