Fields
- Attribute
- The category that displays about the volume pair.
- Value
- Displays status information about volumes that are participating in Metro Mirror relationships.
- Source nickname
- The nickname of the source volumes. If you click on the volumes link,
open systems or zSeries® volume
properties page is displayed.
- Source number
- The volume numbers of
the source volumes.
- Target nickname

the target volumes.
- Created
- The date and time that the relationship was created.
- Last refresh
- The date and time that the target volume in the specific relationship
was refreshed.
- Properties
- The copy states of the volume pairs is displayed based on the following
criteria:
- Last suspended
- The date and time that the specified relationship was suspended.
- Status
- The status of the volume pair in the Metro Mirror relationship:
- Full duplex
- The state of the volume pair whose source and target volumes are in sync;
that is, both source and target volumes contain exactly the same data. This
state is also referred to as full copy mode.
- Copy pending
- The state of the volume pair after the Metro Mirror relationship
is created, but the source and target volume are out of sync. In that case,
data still must be copied from the source to the target volume of a Metro Mirror pair.
- Suspended
- The state of the volume pair when the source and target storage units
cannot communicate anymore, or when the pair is suspended manually. In this
state, write operations to the source volume are not mirrored onto the target
volume and the target volume becomes out of sync. During this time, a bitmap
record of the changed tracks is kept in the source volume. Later, when the
volumes are re-synchronized, only the tracks that were updated are copied.
- No new status
- The state of the volume pair is not available.
Full duplex and copy pending status apply only to Metro Mirror relationships.
- Suspend Reason
- The reason for the volume pair suspension.
- Read access to the target
- Displays whether read access to the target volume is allowed while the
target volume of the selected relationship is active.
- Refresh interval
- Specifies a refresh interval that determines how often this page is refreshed,
based on the following categories:
- Refresh now
- Disable
- 1 minute
- 2 minutes
- 5 minutes
- 15 minutes
- Out-of-sync tracks
