list vsc
Description The list vsc command displays the volume size configuration details for normal and custom
volumes. Each LDEV is identified by the domain, parity group, VDEV, CU, and LDEV.
list vsc has the following information associated with it:
• Domain. The domain to which an LDEV’s parity group belongs. The XP128 can have 1 or 2
domains, the XP1024 can have up to 8 domains, the XP10000 can have upto 4 domains, and
the XP12000 can have up to 18 domains.
• PG. The parity group number to which an LDEV belongs. The XP128/XP1024 has between 1
and 32 parity groups per domain. The XP10000 has 15 parity groups per domain and
XP12000 has between 1 and 16 parity groups per domain.
• Vdev. A VDEV is a subdivision of a parity group and depends on the RAID level of the parity
group and the hard disk capacity. The XP128/XP1024 can have 1 to 16 VDEVs per PG. The
XP10000/XP12000 can have 1 to 18 VDEVs per PG.
• CU. The CU to which the LDEV belongs. For the XP128/XP1024, the CU numbers range from 0
to 31. For the XP10000/XP12000, CU numbers range from 0 to 63. CUs are displayed in
hexadecimal format.
• LDEV. The LDEV number. Each CU can have LDEVs in the range from 0 to 255. LDEVs are
displayed in hexadecimal format.
• Emulation. The emulation type of the LDEV. The CLI displays only open volume emulations. For
LUSE volumes, the emulation type is displayed as OPEN-X * n, where n represents the total
number of LDEVs that comprise the LUSE volume.
• Capacity (MB). The size of the LDEV in megabytes.
• RAID. The RAID level of the parity group to which an LDEV belongs. The supported RAID levels
are RAID1, RAID5, and RAID6.
• LDevType. The kind of LDEV (custom or normal).
