The Install CV pane (1) has the following features:

• Parity Gr

oup: 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 VDEV number starts with E (for example, E1-1-(1)), the VDEV belongs to a parity group that

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).

for RAID5 (7D+1P) or RAID6 (6D+2P), and 256 LDEVs for other RAID levels.

• Capacity Unit: Unit the CVS volume's capacity is displayed in.

• MB: Megabytes (MB). This unit is used for specifying the capacity of open-system volumes.
