CLI Guide

Optional.
● all: Show all volumes.
● base: Show only virtual volumes that are not snapshots of any other volume.
● snapshot: Show only snapshots.
● standard: Show only standard volumes.
● primary-volume: Show only primary volumes.
● secondary-volume: Show only secondary volumes.
If this parameter is omitted, all volumes are shown.
vdisk vdisks
Optional. A comma-separated list of the names or serial numbers of the vdisks containing the
volumes to show. A name that includes a space must be enclosed in double quotes.
volumes
Optional. A comma-separated list of the names or serial numbers of volumes for which to show
information. A name that includes a space must be enclosed in double quotes.
Output
Properties are described in alphabetical order.
Action
If Health is not OK, this field shows recommended actions to take to resolve the health issue.
Alloc Size
The amount of space currently allocated to a virtual volume, or the total size of a linear volume.
Cache Opt
Shown by the details parameter. The cache optimization mode:
● standard: This controller cache mode of operation is optimized for sequential and random I/O
and is the optimization of choice for most workloads. In this mode, the cache is kept coherent
with the partner controller.
● no-mirror: In this mode of operation, the controller cache performs the same as the standard
mode with the exception that the cache metadata is not mirrored to the partner. While this
improves the response time of write I/O, it comes at the cost of redundancy. If this option is
used, the user can expect higher write performance but is exposed to data loss if a controller fails.
Class
● Linear: The volume is in a linear pool.
● Virtual: The volume is in a virtual pool.
Desc
Shown by the details parameter. Blank if not set.
Health
● OK
● Degraded
● Fault
● N/A
● Unknown
Large Virtual Extents
For a virtual volume, this shows whether the system will try to allocate pages in a sequentially
optimized way to reduce I/O latency and improve performance.
● disabled or off: Optimized page allocation is disabled. This is the default.
● enabled or on: Optimized page allocation is enabled.
Name
The name of the volume.
Pool
The name of the pool that contains the volume.
