To remove disks from a running cluster
Determine FlashGrid names of the drives to be removed, e.g. rac2.shared-7:
$ flashgrid-cluster drives
- If the drives are members of an ASM disk group then drop the drives from the disk group. Example:
SQL> alter diskgroup MYDG drop disk RAC1$SHARED_7 drop disk RAC2$SHARED_7 rebalance wait;
Prepare the disks for removal. Example:
[fg@rac1 ~] $ sudo flashgrid-node stop-target /dev/flashgrid/rac1.shared-7 [fg@rac2 ~] $ sudo flashgrid-node stop-target /dev/flashgrid/rac2.shared-7
- Detach the disks from the VMs.
