CLI Guide

• never-delete: Snapshots will never be deleted.
• high: Snapshots may be deleted after all eligible medium-priority snapshots have been deleted.
• medium: Snapshots may be deleted after all eligible low-priority snapshots have been deleted.
• low: Snapshots may be deleted.
Snapshots that are mapped or are not leaves of a volume's snapshot tree are not eligible for automatic
deletion.
Tier Affinity
Shown by the details parameter.
• No Affinity: This setting uses the highest available performing tiers first and only uses the Archive
tier when space is exhausted in the other tiers. Volume data will swap into higher performing tiers based
on frequency of access and tier space availability.
• Archive: This setting prioritizes the volume data to the least performing tier available. Volume data can
move to higher performing tiers based on frequency of access and available space in the tiers.
• Performance: This setting prioritizes volume data to the higher performing tiers. If no space is available,
lower performing tier space is used. Performance affinity volume data will swap into higher tiers based
upon frequency of access or when space is made available.
Total Size
The total size of the volume.
Type
• base: Base volume
• standard: Standard volume
Vdisk
The name of the vdisk that contains the volume.
WR Policy
Shown by the details parameter. The cache write policy:
• 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.
WWN
Shown by the details parameter. The World Wide Name of the volume
