View Pair Synchronization Rate window

Use this window to view the percentage of synchronized data between the P-VOL and S-VOL. This window includes the Pairs table.

For more information about using this window, see the topic on monitoring synchronization rates by clicking Show All Contents and then selecting In-System Replication to navigate to the desired software and information.

Pairs table

The following table shows 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 only.

The pair type.

Values:

  • SI-L1: SI-L1

  • SI-L2: SI L2

Snapshot Group

HTI only.

The snapshot group name. A hyphen (-) is displayed when other than HTI pairs.

If you have not assigned the pair to a snapshot group, this item is blank.

Status

The status for the pair.

For more information about pair status, click Show All Contents and then select In-System Replication to navigate to the desired software and status information.

Synchronization Rate (%)

For SI:

The synchronization rate (%) between P-VOL and S-VOL.

For HTI:

The rate at which the current S-VOL matches the next new generation of the S-VOL. If the S-VOL is the latest one, the storage system computes the synchronization rate by comparing the S-VOL and the P-VOL.

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 only.

The system option that determines 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.
