Pairs table

The following table describes the items in this table.

Item

Description

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

SI and SIz only.

The pair type.

Values:

  • SI-L1: SI L1 pair

  • SI-L2: SI L2 pair

  • (VSP G1000, G1500, and VSP F1500) SIMF: SIz

Snapshot Group (VSP G1000, G1500, and VSP F1500)

HTI 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, select In-System Replication to navigate to the desired software and status information.

Synchronization Rate (%)

For SI:

  • 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.

For SIz:

  • 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 Suspend/SUSPER, the synchronization rate between P-VOL and S-VOL is displayed.

  • If the pair status is Resync/PENDING changed from Suspend/SUSPER, the copy progress rate is displayed.

  • If the pair status is Resync/PENDING changed from other than Suspend/SUSPER, the synchronization rate between P-VOL and S-VOL is displayed.

  • If the pair status is Deleting/TRANS, a hyphen is displayed.

For HTI with invalid cascade attribute:

  • The synchronization rate 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 computed by comparing the S-VOL and the P-VOL.

For HTI with 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.

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

SI and SIz only.

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

(VSP G1000, G1500, and VSP F1500)

Indicates whether cascade pairs can be created.

Enabled: Cascade pairs can be created.

Disabled: Cascade pairs cannot be created.

A hyphen appears for pairs that are not HTI.

Type

(VSP G1000, G1500, and VSP F1500)

The pair type.

Snapshot: The pair has the snapshot attribute.

Clone: The pair has the clone attribute

A hyphen appears for pairs that are not HTI.

Topology ID

(VSP G1000, G1500, and VSP F1500)

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.
