For LUNs that are thin capable - and in use in subdisks but not yet thin reclaimed
The disks should also be removed from the diskgroup with previous
# vxdg -g DG_name -k rmdisk DM_name
and then all the corresponding plex and subdisk objects associated with that DM_name are also removed with vxedit command
VxVM vxdg ERROR V-5-1-553 Disk DM_name is used by one or more subdisks
Procedure TECH130893 not correctly followed.
Provision a thin capable lun and make sure visible to VxVM
# vxdisk set DA_name thin=reclaim
# vxdg -g DG_name -k adddisk DM_name=DA_name
# vxdisk reclaim DA_name
At the vxdisk reclaim command - one of the following errors will be output - they can be ignored.
V-5-1-462 Cannot get records form vxconfigd: Invalid data in request
Disk DM_name: Skipped. No VxFS file system found.
# vxprint -g DG_name -lz | grep DM_name check no subdisk records exist
# vxdg -g DG_name rmdisk DM_name
Repeat for all other removed LUNs.
Any thin provisioned system where :vxdg -k rmdisk" - seen in following vxprint
# vxprint -g DG_name -lz | grep DM_name will have DM record as well as a subdisk
