User issues a Drop Disk command from ASM, Disk gets dropped from the ASM Disk Group.
Rebalance starts and finishes successfully.
Post this, the same cell disk goes into Predective Failure state.
At this time,
cellsrv will issue drop of griddisk at ASM side for the disks which are known to cellsrv,
and not for the disks which were dropped manually.
After the Disk Replacement,
Grid Disks which were dropped manually from the ASM DiskGroup, before the failure, will not be added back.
Grid Disks which were dropped by Cellsrv will be added back to ASM diskgroups.
