• Parity Group: Selected free space's VDEV number. The VDEV number indicates the parity group

where the VDEV belongs. For example, if VDEV number 1-1-(1) appears, the VDEV belongs to

parity group number 1-1.

NOTE:

If a parity group number starts with E (for example, E1-1), the parity group consists of one or more

external LUs.

NOTE:

If a VDEV number starts with V (for example, V1-1-(1)), the VDEV belongs to a parity group that

consists of one or more virtual volumes (V-VOLs).

• Emulation Type: Emulation type.

• Capacity Unit: Unit (MB, Cyl, or block) used to display the volume capacity.

50 - 7168 Cyl,or315 - 8513 bl oc ks ). The value can be incremented by 1 MB, cylinder, or block.

• Emulation:CVSvolume'semulationtype.

• Capacity: CVS volume's capacity displayed in the unit selected from the Capacity Unit list.

• Available LDEVs: Number of LDEVs that can be created in the VDEV. The maximum is 512 LDEVs

for RAID5 (7D+1P), and 256 LDEVs for other RAID levels.
