Description
Use this field to change the name of the storage pool. It can be up to 32
alphanumeric characters and spaces.
You can change the Parity Mode. Your options are based on the current
setting and available disk drives. For more information on Parity
management, see Parity Management
Possible options include:
• No parity available.
• Single-parity protection only.
• Single- or dual-parity protection available.
NOTE: Increasing the parity level always requires the addition of an
unassigned disk to the storage pool. In addition, it may require
the installation of additional disks if none are currently
available.
Use the drop-down list to choose a percentage of the storage pool that
you want reserved for snapshots. You can only decrease the current
reserved space from the Properties page.
NOTE: If you grow the storage pool by adding a drive and not changing
the parity mode, you can allocate the new space to increase
snapshot space.
