Mirror Unit

The mirror unit number.

Virtual Storage Machine

The model type and serial number of the virtual storage machine to which the P-VOL and S-VOL belong.

Virtual LDEV ID

The identification number of the virtual LDEV for the P-VOL and S-VOLs.

If no virtual LDEV ID is assigned, a blank is displayed.

Pairs table

The following table shows the items in this table on the View Pair Properties window.

Item

  • Basic: Internal volume

  • DP: DP-VOL

  • External: External volume

  • Attribute: The P-VOL's attribute.

  • Capacity: The P-VOL's volume capacity.

  • CLPR: The P-VOL's CLPR ID.

  • Encryption: The P-VOL's encryption information.

  • Enabled: Encryption is enabled for the parity group to which the P-VOL's LDEV belongs, or a V-VOL is associated with a pool in which a pool volume has encryption enabled.

  • Disabled: Encryption is disabled for the parity group to which the P-VOL's LDEV belongs, or a V-VOL is associated with a pool in which a pool volume has encryption disabled.

  • Mixed: The pool to which the P-VOL's LDEV belongs contains both pool volumes for which encryption is enabled and ones for which encryption is disabled.

Note: Data encryption is not ensured in an LDEV with Mixed encryption status.

For DP-VOLs, the pool to which an LDEV belongs is an external volume or blocked.

For an external volume, a hyphen (-) is displayed.

  • T10 PI: The P-VOL's T10 PI attribute.

  • Enabled: The T10 PI attribute is enabled.

  • Disabled: The T10 PI attribute is disabled.

  • 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.

Snapshot Group

HTI only.

The snapshot group name.

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, navigate to the desired software and status information. To do this, click Show All Contents and then select In-System Replication.

Secondary Volume

The S-VOL information.

Values:

  • LDEV ID: The S-VOL's LDEV identifier.

  • LDEV name: The S-VOL's LDEV name.

  • Provisioning type: The S-VOL's provisioning type, which can be one of the following:

  • Basic: Internal volume

  • DP: DP-VOL

  • External: External volume

  • Snapshot: HTI volume

  • Attribute: The S-VOL's attribute.

  • Capacity: The S-VOL's volume capacity.

  • CLPR: The S-VOL's CLPR ID.

  • Encryption: The S-VOL's encryption information.

  • Enabled: Encryption is enabled for the parity group to which the S-VOL's LDEV belongs, or a V-VOL is associated with a pool in which a pool volume has encryption enabled.

  • Disabled: Encryption is disabled for the parity group to which the S-VOL's LDEV belongs, or a V-VOL is associated with a pool in which a pool volume has encryption disabled.

  • Mixed: The pool to which the S-VOL's LDEV belongs contains both pool volumes for which encryption is enabled and ones for which encryption is disabled.

Note: Data encryption is not ensured in an LDEV with Mixed encryption status.

For DP-VOLs, the pool to which an LDEV belongs is an external volume or blocked.

For an external volume, a hyphen (-) is displayed.

  • Mode: Indicates whether the storage system has written to the S-VOL. For SI, this item also indicates whether the storage system can read the S-VOL.

  • For SI:

- W is shown when the storage system has written data to the S-VOL. W is also shown when the storage system has written data to the S-VOL and the S-VOL cannot be read when its pair status is "PSUS(SP)/PSUS" or "PSUS".

- N is shown when the S-VOL cannot be read because you specified "-m noread" using CCI.

- A hyphen (-) indicates that the storage system has not written to the S-VOL.

  • For HTI:

- W is shown if the storage system has written data to the S-VOL when its pair status is "PSUS".

- A hyphen (-) indicates that the storage system has not written to the S-VOL.

  • T10 PI: The S-VOL's T10 PI attribute.

  • Enabled: The T10 PI attribute is enabled.

  • Disabled: The T10 PI attribute is disabled.

  • 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.

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.
