Removing disks (FlashGrid Server on Azure)

  • Updated
  • Products: FlashGrid Server on Azure

  1. Determine FlashGrid names of the disks to be removed, e.g. myhostname.lun3 or myhostname.lun4:

    [fg@myhostname ~]$ flashgrid-node

  2. If the disks are members of an ASM disk group then drop them from the disk group. Example:

    SQL> alter diskgroup MYDG
drop disk MYHOSTNAME$LUN3
drop disk MYHOSTNAME$LUN4
rebalance wait;

    Wait till the Resync=No for the disk group in the flashgrid-cluster output. It may take a while to resync the disk group depending on the amount of data, disk performance characteristics, and instance parameters.

  3. Prepare the disks for removal. Example

    [fg@myhostname ~]$ flashgrid-node stop-target /dev/flashgrid/myhostname.lun3
    [fg@myhostname ~]$ flashgrid-node stop-target /dev/flashgrid/myhostname.lun4
  4. Detach the disks from the VM.
