Primary Volume
|
The P-VOL information.
Values:
- LDEV ID: The P-VOL's LDEV identifier.
- LDEV Name: The P-VOL's LDEV name.
- CLPR: The P-VOL's CLPR ID.
- Virtual Storage Machine: The model type and serial number of the virtual storage machine to which the P-VOL belongs.
- Virtual LDEV ID: The identification number of the P-VOL's virtual LDEV. If no virtual LDEV ID is assigned, a blank is displayed.
- Virtual Device Name: The name of the P-VOL's virtual device, in a combined format of
virtual emulation type,
number of virtual LUSE volumes, and
virtual CVS attribute. Each of these three items is displayed only if it is specified. If none of them are specified, a blank is displayed. "CVS" is displayed at the end of the device name, if the virtual CVS attribute is specified.
- Virtual SSID: The virtual SSID of the P-VOL. If no virtual SSID is specified, a blank is displayed.

Copy Type
|
Not displayed for HTI pairs.
The pair type.
Values:
- SI-L1: SI L1 pair
- SI-L2: SI L2 pair
- (VSP 5000 series)
SIMF: SIz pair
|
|
Snapshot Group
|
Displayed for HTI pairs only.
The snapshot group name.
If you have not assigned the pair to a snapshot group, a blank is displayed.
|
|
Status
|
The status of the pair.
For more information about pair status,
see
Device Manager - Storage Navigator pair status names and descriptions.

Synchronization Rate (%)
|
For SI pairs:
- If the pair status is COPY(PD)/COPY, COPY(SP)/COPY, or PSUS (SP)/PSUS, the copy progress rate is displayed.
- If the pair status is PAIR, PSUS, COPY(RS-R)/RCPY, or PSUE, the synchronization rate between P-VOL and S-VOL is displayed.
- If the pair status is COPY(RS)/COPY changed from PSUE, the copy progress rate is displayed.
- If the pair status is COPY(RS)/COPY changed from other than PSUE, the synchronization rate between P-VOL and S-VOL is displayed.
- If the pair status is SMPL(PD), a hyphen is displayed.
(VSP 5000 series) For SIz pairs:
- If the pair status is PENDING, SP-Pend/TRANS, or V-Split/SUSPVS, the copy progress rate is displayed.
- If the pair status is DUPLEX, Split/SUSPOP, Resync-R/REVRSY, or PSUE, the synchronization rate between P-VOL and S-VOL is displayed.
- If the pair status is Resync/PENDING changed from PSUE, the copy progress rate is displayed.
- If the pair status is Resync/PENDING changed from other than PSUE, the synchronization rate between P-VOL and S-VOL is displayed.
- If the pair status is Deleting/TRANS, a hyphen is displayed.
For Thin Image Advanced pairs, a hyphen is displayed.
For HTI pairs with an invalid cascade attribute:
- The synchronization rate is computed by comparing the current S-VOL and the next new generation of the S-VOL.
- When the S-VOL is the latest one, the synchronization rate is computed by comparing the S-VOL and the P-VOL.
- To display the progress rate, enable Display Progress Rate of System Option #17 in the Edit Local Replica Options window.
Note: Synchronization Rate is not available for Thin Image Advanced.
For HTI pairs with a valid cascade attribute, according to pair status:
- When the pair status is PAIR, PSUS, or PSUE, the synchronization rate is computed by comparing the current S-VOL and the next new generation of the S-VOL. If the S-VOL is the latest one, the synchronization rate is computed by comparing the S-VOL and the P-VOL.
- When the pair status is COPY, PSUS(SP), RCPY, or SMPL(PD), the synchronization rate is computed by the progress rate of each process.
Note: Synchronization Rate is not available for Thin Image Advanced.

Secondary Volume
|
The S-VOL information.
Values:
- LDEV ID: The S-VOL's LDEV identifier.
- LDEV Name: The S-VOL's LDEV name.
- CLPR: The S-VOL's CLPR ID.
- Virtual Storage Machine: The model type and serial number of the virtual storage machine to which the S-VOL belongs.
- Virtual LDEV ID: The identification number of the S-VOL's virtual LDEV. If no virtual LDEV ID is assigned, a blank is displayed.
- Virtual Device Name: The name of the S-VOL's virtual device, in a combined format of
virtual emulation type,
number of virtual LUSE volumes, and
virtual CVS attribute. Each of these three items is displayed only if it is specified. If none of them are specified, a blank is displayed. "CVS" is displayed at the end of the device name, if the virtual CVS attribute is specified.
- Virtual SSID: The virtual SSID of the S-VOL. If no virtual SSID is specified, a blank is displayed.

|
Copy Pace
|
Not displayed for HTI pairs.
The system option that determines the rate at which you want the storage system to copy data.
Values:
- Slower: Improved host
server
I/O performance but slower processing speed.
- Medium: Average processing speed and host
server
I/O performance.
- Faster: Faster processing speed but slower host
server
I/O performance.

Mirror Unit
|
The mirror unit number.
|
| Cascade |
Indicates whether cascade pairs can be created.
Enabled: Cascade pairs can be created.
Disabled: Cascade pairs cannot be created.
For non-HTI pairs, a hyphen is displayed.
|
| Type |
The pair type.
Snapshot: The pair has the snapshot attribute.
Clone: The pair has the clone attribute or diff clone attribute. In the TI Pairs window, if Diff Compare Volume displays the LDEV ID, the diff clone attribute is set for the pair. If Diff Compare Volume displays a hyphen (-), the clone attribute is set for the pair
For non-HTI pairs, a hyphen is displayed.
|
| Topology ID |
The topology ID, which indicates the layer of the pair based on the mirror unit. The topology ID consists of the LDEV ID of the volume (root volume for Thin Image pairs), which is the base of the target pair, and the mirror unit number. |
