Viewing information about a volume
In the Configuration View panel, right-click a volume and select View > Overview. The Volume Overview table shows:
• Component. Volume or Maps.
• Count. The quantity of mappings for the volume.
• Capacity. The capacity of the volume.
• Storage Space. The space usage of the volume. For descriptions of storage-space color codes, see "About
storage-space color codes" (page 29).
• Replication Addresses. The quantity of replication addresses for the volume.
• Replication Images. The quantity of replication images for the volume.
Select a component to see more information about it.
Volume properties
When you select Volume in the Volume Overview table, the Properties for Volume table shows:
• Vdisk Name. Name of the vdisk that the volume is in.
• Name. Volume name.
• Size. Volume size.
• Preferred Owner. Controller that owns the vdisk and its volumes during normal operation.
• Current Owner. Either the preferred owner during normal operation or the partner controller when the preferred
owner is offline.
• Serial Number. Volume serial number.
• Cache Write Policy. Write-back or Write-through. See "Using write-back or write-through caching" (page 21).
• Cache Optimization. Standard or No-mirror. See "Optimizing read-ahead caching" (page 21).
• Read Ahead Size. See "Optimizing read-ahead caching" (page 21).
• Type. Standard volume, master volume, or snapshot.
• Progress. If the volume is being created by a volume-copy operation, the percent complete.
• Snapshot. Specifies whether the selected volume is a snapshot.
• Health. OK, Degraded, Fault, or Unknown.
Health Reason. If Health is not OK, this field shows the reason for the health state.
• Health Recommendation. If Health is not OK, this field shows the recommended actions to take to resolve the
health issue.
For a local primary or secondary volume, the Replication Properties for Volume table shows:
• Name. Replication volume name.
• Serial Number. Replication volume serial number.
• Status. Replication volume status:
• Initializing: The initial (full) replication to the volume is in progress.
• Online: The volume is online and is consistent with the last replicated image.
• Inconsistent: The volume is online but is in an inconsistent state. A full replication is required to initialize it.
• Replicating: The volume is online and replication is in progress.
• Replicate-delay: The volume is online but the in-progress replication has been temporarily delayed; a retry is
occurring.
• Suspended: The volume is online but the in-progress replication has been suspended.
• Offline: The volume cannot be accessed or is unusable due to an error.
• Establishing proxy: The volume is establishing a proxy connection to a remote volume. This will occur when a
detached secondary volume is reattached and is re-establishing a connection with the primary system in
preparation for replication.
• Detached: The volume is detached for removal.
