AIX : Remove Filesystem , Volume Group And Reclaim Associated SAN Disk
Geeks ,
Today we will see some basic set of operation to free SAN disk from AIX server and to make those disks ready/available for SAN (storage team) to reclaim.
lspv | wc -l <- its like lsscsi , here we will count total number of devices before removal
lsvg -p testvg <- it will give powerdisk associated with testvg (take all powerdisk names in a file)
powermt display dev=<powerdisk> <- it will give powerdisk paths and logical ID of powerdisk (take all paths name in a file for all powerdisks)
lsvg -l testvg <- it will list filesystems under testvg i.e. /test
fuser -cu /test <- to check if FS is in use or not
umount /test <- to unmount /test
rmfs -ir /test <- it will remove filesystem and data ( i=to show warning, r=to remove mount point )
reducevg <vgname i.e. testvg > <pwrdsk> <- it will remove phy vol from a vol grp , when all phy vol removed, the vol grp will be deleted
powermt remove dev=<powerdisk> <- remove powerdisk from powermt control
rmdev -dl <paths_of_powerdisks> <- remove a device from the system (disk paths)
rmdev -dl <power disks> <- once paths removed, then remove power disks.
lspv | wc -l <- now compare this count with starting count
That`s it , Now just sit behind , take a cup of coffee and wait for those nasty disks to be fetched out by SAN team.
Cheers !!
