Primary Volume

The P-VOL information.

Values:

• LDEV IDThe P-VOL's LDEV identification number. Click to open the LDEV Properties window. Use this window to search for P-VOL information.
• LDEV NameThe P-VOL's LDEV name.
• CLPRThe P-VOL's CLPR ID.
• Virtual Storage MachineThe model type and serial number of the virtual storage machine to which the P-VOL belongs.
• Virtual LDEV IDThe identification number of the P-VOL’s virtual LDEV. If no virtual LDEV ID is assigned, a blank is displayed.
• Virtual Device NameThe 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.
• Virtual SSIDThe virtual SSID of the P-VOL. If no virtual SSID is specified, a blank is displayed.

Copy Type

The SI volume’s copy type.

Values:

• SI-L1SI L1 pair
• SI-L2SI L2 pair
• SIMFSIz pair

Snapshot Group

The HTI snapshot group name.

If you have not configured a snapshot group for the HTI pair, this item is blank.

Status

The pair status.

For more information about HTI pair status, see Thin Image pair status definitions.

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.

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 Thin Image pairs, the displayed information depends on whether the cascade attribute is enabled or disabled.

• For Thin Image pairs where the cascade attribute is enabled, the following information is displayed depending on the pair status:
  • If the pair status is PAIR, PSUS, or PSUE, the pair synchronization rate shows the rate that current S-VOL data matches that of the next generation of the S-VOL. If the S-VOL is the latest one, the synchronization rate is computed by comparing the S-VOL with the P-VOL.
  • If the pair status is COPY, PSUS(SP), RCPY, or SMPL(PD), the progress rate of each process is displayed.
  • For Thin Image pairs with the cascade attribute disabled, the pair synchronization rate that the current S-VOL data matches that of the next generation of the S-VOL is displayed. If the S-VOL is the latest one, the synchronization rate is computed by comparing the S-VOL with the P-VOL.

    To display the progress rate, enable Display Progress Rate of the system option #17 in the Edit Local Replica Options window.

    • If the pair status is COPY, RCPY, or SMPL(PD), the progress rate for each process is displayed.
    • If the pair status is PAIR, PSUS, or PSUE, the synchronization rate is displayed in the same way as when the system option #17 is not set.

    For information about how to enable the local replica options, see Changing local replica options that affect Thin Image performance.

Secondary Volume

The S-VOL information.

Values:

• LDEV IDThe S-VOL's LDEV identification number. Click to open the LDEV Properties window.
• LDEV NameThe S-VOL's LDEV name.
• CLPRThe S-VOL's CLPR ID.
• Virtual Storage MachineThe model type and serial number of the virtual storage machine to which the S-VOL belongs.
• Virtual LDEV IDThe identification number of the S-VOL’s virtual LDEV. If no virtual LDEV ID is assigned, a blank is displayed.
• Virtual Device NameThe 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.
• Virtual SSIDThe virtual SSID of the S-VOL. If no virtual SSID is specified, a blank is displayed.

Mirror Unit

The mirror unit number.

Cascade

Indicates whether a cascaded pair can be created

• Enabled Cascaded pairs can be created.
• Disabled Cascaded pairs cannot be created.

A hyphen (-) is displayed for non-HTI pairs.

Type

The pair type.

• Snapshot A pair with the snapshot attribute.
• Clone A pair with 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.

A hyphen (-) is displayed for non-HTI pairs.

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) and the mirror unit number.
