Replication Sets table in the Volumes topic
To see information about the replication set for a volume or volume group, select a volume in the volumes table. If it is not
already selected, select the Replication Sets tab. The replication appears in the Replication Sets table.
The Replication Sets table shows the following information. By default, the table shows 10 entries at a time.
● Name – Shows the replication set name.
● Primary Volume – Shows the primary volume name. For replication sets that use volume groups, the primary volume name
is volume-group-name. * , where .* signifies that the replication set contains more than one volume. If the volume is on
the local system, the
icon appears.
●
Secondary Volume – Shows the secondary volume name. For replication sets that use volume groups, the secondary
volume name is volume-group-name.* , where .* signifies that the replication set contains more than one volume. If the
volume is on the local system, the icon appears.
● Status – Shows the status of the replication set:
○ Not Ready – The replication set is not ready for replications because the system is still preparing the replication set.
○ Unsynchronized – The primary and secondary volumes are unsynchronized because the system has prepared the
replication set, but the initial replication has not run.
○ Running – A replication is in progress.
○ Ready – The replication set is ready for a replication.
○ Suspended – Replications have been suspended.
○ Unknown – This system cannot communicate with the primary system and thus cannot be sure of the current state of
the replication set. Check the state of the primary system.
● Last Successful Run – Shows the date and time of the last successful replication.
● Estimated Completion Time – Shows the estimated date and time for the replication in progress to complete.
NOTE:
If you change the time zone of the secondary system in a replication set whose primary and secondary systems
are in different time zones, you must restart the system to enable management interfaces to show proper time values for
replication operations.
To see more information about a replication set, hover the cursor over the replication set in the table. The Replication Set
Information panel opens and displays detailed information about the replication set.

Schedules table in the Volumes topic
For information about the schedules for a snapshot, select the snapshot in the volumes table. For information about the
schedules for copy operations for a volume, select the volume in the volumes table. For information about the schedules for a
replication set, select a volume for the replication set in the volumes table. If it is not already selected, select the Schedules tab.
The schedules appear in the Schedules table.
The Schedules table shows the following schedule information. By default, the table shows 10 entries at a time.
● Schedule Name – Shows the name of the schedule.
● Schedule Specification – Shows the schedule settings for running the associated task.
● Status – Shows the status for the schedule:
○ Uninitialized – The schedule is not yet ready to run.
○ Ready – The schedule is ready to run at the next scheduled time.
○ Suspended – The schedule had an error and is holding in its current state.
○ Expired – The schedule exceeded a constraint and will not run again.
○ Invalid – The schedule is invalid.
