Response Parameters

Standard Output

The command returns the following information about the pool snapshots on the server:

Label

Description

Name

Name of the snapshot

Pool

Name of the pool being snapped

Mounted

Yes or No; whether the snapshot is mounted as a pool

Size

Size of the pool in MB, GB, or TB

Shared

Yes or No; whether the snapshot’s device is marked as Shareable for Clustering. Typically, No, because snapshots are not supported for clustered pools at this time.

More Output

Snapshot chunk size in KB (ex: 128)
