Table 143. volumes properties (continued)
Name Type Description
size string Volume capacity, formatted to use the current base, precision, and units.
size-numeric uint64 Unformatted size value in blocks.
total-size string The total size of the volume.
total-size-numeric uint64 Unformatted total-size value in blocks.
allocated-size string The amount of space currently allocated to a virtual volume, or the total size of a linear
volume.
allocated-size-numeric uint64 Unformatted allocated-size value in blocks.
storage-type string
• Linear: The volume is in a linear pool.
• Virtual: The volume is in a virtual pool.
storage-type-numeric uint32 Numeric equivalents for storage-type values.
• 0: Linear
• 1: Virtual
preferred-owner string Controller that owns the volume during normal operation.
• A: Controller A.
• B: Controller B.
preferred-owner-numeric uint32 Numeric equivalents for preferred-owner values.
• 0: B
• 1: A
owner string Either the preferred owner during normal operation or the partner controller when the
preferred owner is offline.
• A: Controller A.
• B: Controller B.
owner-numeric uint32 Numeric equivalents for owner values.
• 0: B
• 1: A
serial-number string Volume serial number.
write-policy string
• write-back: Write-back caching does not wait for data to be completely written
to disk before signaling the host that the write is complete. This is the preferred
setting for a fault-tolerant environment because it improves the performance of
write operations and throughput.
• write-through: Write-through caching significantly impacts performance by
waiting for data to be completely written to disk before signaling the host that the
write is complete. Use this setting only when operating in an environment with low
or no fault tolerance.
write-policy- numeric uint32 Numeric equivalents for write-policy values.
• 0: write-through
• 1: write-back
cache-optimization string
• 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. This mode gives you high
performance and high redundancy.
