Viewing replication properties, addresses, and images for a volume 139
Viewing replication properties, addresses, and images for a volume
In the Configuration View panel, right-click a volume and select View > Overview. The Volume Overview table shows:
• As described in "Viewing information about a volume" (page 106): the capacity and space usage of the volume;
the quantity of mappings for the volume; and the quantity of task schedules for the volume
• The quantity of replication addresses for the volume
• The quantity of replication images for the volume
For descriptions of storage-space color codes, see "About storage-space color codes" (page 29).
Select a component to see more information about it.
Replication properties
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.
• Status-Reason. More information about the status value, or N/A for Online status.
• Monitor. Replication volume monitoring status:
• OK: Communication to the remote volume is successfully occurring on the FC or iSCSI network.
• Failed: Communication to the remote volume has failed because of an FC or iSCSI network issue or because
the remote volume has gone offline.
• Location. Local or Remote.
• Primary Volume Name. Primary volume name. If the replication set has a primary-volume conflict, all associated
primary volumes are displayed.
• Primary Volume Serial Number. Primary volume serial number. If the replication set has a primary-volume conflict,
all associated primary volumes are displayed.
• Primary Volume Status. Primary volume status: Online, Offline, Conflict, or N/A.
• Maximum Number of Queued Images. Number of replication images to consider when determining the next
image to replicate. Used only if the On Collision parameter is set to Oldest.
• Maximum Retry Time (Seconds). Amount of time in seconds that the replication volume should retry a replication
operation on any specific image when errors occur. Used only if the On Error parameter is set to Retry.
• On Error. Error policy to invoke when errors occur during the replication process: Retry or Suspend.
• Link Type. Type of ports used to link the primary and secondary volumes: FC or iSCSI.
• On Collision. Collision policy used to determine the next image to replicate when multiple replication images are
queued: Newest or Oldest.
• Monitor Interval. Interval in seconds at which the primary volume should query the secondary volume.
• Priority. Priority of the replication process on the replication volume: Low, Medium, or High.
• Connection Status.
