Removing Disks (FlashGrid Cluster on Azure)

To remove disks from a running cluster

1. Determine FlashGrid names of the drives to be removed, e.g. rac2.lun3:

   $ flashgrid-cluster drives

2. 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$LUN3
   drop disk RAC2$LUN3
   rebalance wait;

3. Prepare the disks for removal. Example:

   [fg@rac1 ~] $ flashgrid-node stop-target /dev/flashgrid/rac1.lun3
   [fg@rac2 ~] $ flashgrid-node stop-target /dev/flashgrid/rac2.lun3

4. Detach the disks from the VMs.
