Report field descriptions

ID

Specifies the source and target volume IDs of a remote mirror and copy volume relationship.

State

Displays the current remote mirror and copy volume relationship state. One of the following values is displayed:

Copy Pending

Indicates that the relationship is copy pending. A Global Copy (Extended Distance) relationship is always copy pending.

Full Duplex

Indicates that the relationship is full duplex.

Suspended

Indicates that the relationship is suspended. The Reason attribute might indicate why the relationship is suspended.

Target Copy Pending

Indicates that the source volume is unknown or cannot be queried and the target state is copy pending.

Target Full Duplex

Indicates that the source volume is unknown or cannot be queried and the target state is full duplex.

Target Suspended

Indicates that the source volume is unknown or cannot be queried and the target state is suspended.

Not Part of Remote Copy Pair

Indicates that the relationship is not a remote copy pair.

Invalid State

Indicates that the listed remote mirror and copy volume relationships do not meet the requirements for being valid.

Note: The report that is generated with the invalid-state designation only displays the source and target volume IDs of a remote mirror and copy volume relationship and the state designation of invalid-state. All the other information columns are displayed with a null (-) value.

Volume Inaccessible

Indicates that the volume could not be queried. Generally, this indicates that the volume is fenced.

Note: The report that is generated with the Volume Inaccessible designation only displays the source and target volume IDs of a remote mirror and copy volume relationship and the state designation of Volume Inaccessible. All the other information columns are displayed with a null (-) value.

Reason

Indicates why the Remote Mirror and Copy volume relationship is suspended. The following values can be displayed:

Unknown

Specifies that the volume is suspended but the reason for the suspension is not specifically defined within the system

Not in PPRC Relationship

Specifies that the designated volume is not part of a Remote Mirror and Copy pair.

Host Source

Specifies that the Remote Mirror and Copy processing on the volume was suspended by the primary host. The host command might have specified an immediate suspension or that the volume be suspended when it entered a full duplex state.

Host Target

Specifies that Remote Mirror and Copy processing was suspended on the secondary volume. Updates to primary volumes and out-of-sync tracks are still being processed.

Update Target

Specifies that Remote Mirror and Copy processing was suspended on a secondary volume by the primary control unit update secondary device status command.

Internal Conditions Both

Specifies that Remote Mirror and Copy processing was suspended on a volume by either the primary control unit or the secondary control unit because of internal conditions.

Simplex Target

Specifies that Remote Mirror and Copy processing was suspended on a volume when the secondary control unit sent a state change interrupt to the primary control unit indicating a transition to a simplex state.

Internal Conditions Target

Specifies that Remote Mirror and Copy processing was suspended on a secondary volume when the primary control unit was notified that the secondary volume became suspended due to internal conditions.

Power

Specifies that Remote Mirror and Copy processing was suspended on a volume when the primary or secondary control unit was shut down or restarted.

Notes:

1. The paths to the secondary controller might not be available if the power to the primary controller was shut down. If only the secondary control unit was shut down, it might be possible for the paths to be restored depending on the path status. Use the following process to determine whether your Remote Mirror and Copy processing can be restored on the affected volumes:
   1. Issue the lspprc command and use the generated report to determine the path status.
   2. Issue the mkpprc command if the paths are still in tact. This process resynchronizes the volume pairs.
   3. Continue with your processing.
2. If the above process cannot be performed, you must remove the pair relationships on the affected volumes and start your Remote Mirror and Copy processing from the beginning on the affected volumes.

Freeze

Specifies that Remote Mirror and Copy processing was suspended on a volume pair because the host issued a Freeze PPRC Group order.

Volume Not Configured

Specifies that Remote Mirror and Copy processing was suspended on a volume because the volume is not part of a copy pair relationship.

Type

Indicates that the remote copy and mirror volume relationship is a Metro Mirror (synchronous) relationship, a Global Copy (extended distance) relationship, or the relationship type is unknown.

Out Of Sync Tracks

Indicates the number of tracks that are not synchronized for this FlashCopy relationship. The maximum value is dependent on the source volume size.

Notes:

1. If you issue the lspprc command to view the out of sync value for a volume pair (for example, 0000:0001) on a 2105, there is no observable decrease in the value from when you issue the query to the end of the process.
2. If you issue the lspprc command to view the out of sync value for a single volume (for example, 0000) on a 2105, there is an observable decrease in the value but only at 10 second intervals. If you issue the lspprc command and reissue it again before the 10 seconds has expired, there is no observable change in the value.
3. If you issue the lspprc command to view the out of sync value for a volume pair or a single volume on a 1750, there is an observable decrease in the value but only at 10 second intervals.

Tgt Read

Indicates that Read IO operations to the target volume are allowed.

Src Cascade

Indicates that the source volume of this relationship is enabled to also be a target volume of a different relationship.

Tgt Cascade

Indicates that the target volume of this relationship is enabled so that it is also a source volume for a different relationship.

Date Suspended

Indicates the date when this relationship was last suspended. The value can be displayed as a null (-).

SourceLSS

Indicates the consistency group LSS ID that is associated with the source volume of this PPRC volume relationship.

Timeout (secs)

Indicates the consistency group Long Busy Timeout setting for the LSS ID that is associated with the source volume of this PPRC volume relationship. The timeout value is either the default value of 120 seconds, or a user-specified value of 1 to 600 000 seconds.

Crit Mode

Indicates whether the remote copy and mirror primary volume represents a critical volume.

First Pass Status

Indicates the first pass Global Copy state of the source volume. The data is valid only when you query the primary box and the queried pair is a Global Copy pair.

GMIR CG

Indicates if the remote mirror and copy consistency group is enabled, disabled or not available.

Notes:

1. This value is displayed when you designate the use of the -l parameter and when the primary volume is being queried.
2. This value is not reported for model 2105. If a model 2105 is being queried, the value displayed for this field is N/A (not available).

PPRC CG

Indicates if the volume is in consistent asynchronous remote mirror and copy mode or is not available. The values that can be displayed are enabled, disabled, or not available.

Notes:

1. This value is displayed when you designate the use of the -l parameter.
2. This value is not reported for model 2105. If a model 2105 is using being queried, the value displayed for this field is N/A (not available).
