2.4.5 Drop Pool Disks

A pool disk is a portion of an Exadata storage device that is designated for use by Exascale.

Exascale only supports dropping of pool disks for the purpose of shrinking a storage pool by removing all of the pool disks provided by a storage server. You cannot drop individual pool disks.

To drop the pool disks associated with a storage server:

1. Prepare the pool disks for removal.

   Use the CELLCLI DROP GRIDDISK command with the prepare option. For example:

   CellCLI> drop griddisk all harddisk prefix=pool1 prepare

   This command marks the pool disks for removal and sets the pool disk status to waiting for storage pool reconfig.

   Note:

   If required, you can undo this step before you reconfigure the storage pool by using CELLCLI DROP GRIDDISK command with the cancel option. For example:

   CellCLI> drop griddisk all harddisk prefix=pool1 cancel

2. Reconfigure the storage pool.

   Use the ESCLI chstoragepool command with the --reconfig option. For example:

   @> chstoragepool POOL1 --reconfig

   This command permanently removes the pool disks and rebalances the storage pool.
