Figure 97 Make Volume pane (1) for OPEN-V
This pane has the following features:
• Parity Group: VDEV number of the CVS volume to be initialized. 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).
• Emulation: CVS volume's emulation type (OPEN-V).
• LDEV information table: Displays the following information about the CVS volume settings:
• No.: CVS volume's setting number.
• Emulation: CVS volume's emulation type (OPEN-V).
• 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.
• 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.
• Cyl: Cylinders (Cyl). This unit is used for specifying the capacity of mainframe volumes.
