list parity_group
Description This command displays parity group configurations. Each parity group in the disk array is identified
by its unique parity group name and has the following information associated with it:
• Domain. The domain number of the parity group. For parity group 2-1, the domain number is
“2.”
• PG. The PG number of the parity group. For Parity Group 2-1, the PG number is “1.”
• Raid Type. The RAID type of the parity group (for example, RAID5 (3D+1P).
• Drive Type. The drive type of the parity group (for example, DKR2B-J18FC).
• VDev. A VDEV is a subdivision of a parity group and depends on the RAID level of the parity
group and hard disk capacity.
• Emulation. The emulation type of the parity group. The CLI displays only open volume emulations.
The display shows OPEN-* if a VDEV contains LDEVs that are a mix of emulation types.
• TotalFreeSpace. The total free space (in MB) in the VDEV that can be used for creating new
custom LDEVs.
• IndividualFreeSpace. The individual free spaces (in MB) in the VDEV that can be used for
creating new custom LDEVs. For example, if TotalFreeSpace is 5000, this attribute may specify
two blocks of free space, for example 3000 and 2000.
• InitializeCount. The number of LDEV IDs that need to be given for an initialize operation. To
perform an initialize operation for a particular VDEV, you need to know how many new normal
LDEVs to create. This value gives that number, which is the number of normal volumes deleted on
that VDEV. For the OPEN-V emulation type, a hyphen (-) is displayed in this column.
• Size. The total capacity of the PG.
Syntax list parity_group -fs -emulation -initializecount -domain <domain...>
-pg <PG...> -vdev <vdev...> [-size]
Arguments [-fs]
Displays domains, PGs, VDEVs, and individual free spaces.
[-initializecount]
Displays domains, PGs, VDEVs, and their respective initialize counts.
[-emulation]
Displays domains, PGs, VDEVs, and emulation types.
[-domain <domain...>]
The output is the same as the output of list parity_group except that it displays information only
for specified domains.
[-pg <PG...>]
The output is the same as the output of list parity_group (default) except that it displays
information only for the specified PGs.
[-vdev <vdev...>]
The output is the same as the output of list parity_group (default) except that it displays
information only for the specified VDEVs.
[-size]
Displays the total capacity of the PG/VDEV.
