Description

Local Storage System

Displays the following information about the local system:

  • LDEV ID (LDEV name): P-VOL's LDEV identifier and name, which is displayed when you hover the cursor over it.
  • Number of Paths: Number of data paths between primary and secondary systems.
  • Provisioning Type, Encrypted, T10 PI: Provisioning type, encryption status, and T10 PI attribute of the volume in the local storage system.

    Encryption status is displayed only when the encryption status is Enabled or Mixed. If ... is displayed, place the cursor over ... to open the hidden contents as a tooltip. T10 PI attribute information is displayed only if the T10 PI attribute is enabled.

  • (VSP 5000 series) Emulation Type, Capacity: Emulation type and capacity of the local system.
  • (VSP G/F350, G/F370, G/F700, G/F900, VSP E series) Attribute, capacity: Local system's volume attribute and capacity. If the volume does not have an attribute, only the capacity is displayed.
  • Model/Serial number, CLPR ID : CLPR name: Model, serial number, CLPR ID, and CLPR name of the local system.

Copy Type, Status

Copy type and pair status of the pair.

Path Group

Path group of the pair.

If the P-VOL is in the primary storage system you can click one of the following to display the remote path list.

  • Path group ID (TC)
  • (VSP 5000 series) Remote Paths (TCz). Displayed only when the P-VOL is located at the local storage system.

Remote Storage System

Displays the following information about the remote system:

  • LDEV ID: S-VOL's LDEV identifier and name, which is displayed when you hover the cursor over it.
  • Port ID/Host Group ID or iSCSI Target ID/LUN ID: Port, host group or iSCSI target, and LUN identifiers. Information is useful when specifying an LDEV ID at pair creation. It does not change, even if path settings are changed. (TC only).
  • (VSP 5000 series) Emulation type: Remote system's volume emulation type.
  • (VSP G/F350, G/F370, G/F700, G/F900, VSP E series) Capacity: Remote system's volume capacity.
  • Model/Serial number: Remote system's model, serial number.

    (VSP 5000 series) For CU-by-CU connection, SSID is also displayed.

Description

Status

Pair's status

Processing Status

The processing status for a pair volume is displayed.

  • Expanding: The capacity of a TC pair volume is being expanded.

If the volume capacity is not being expanded, or if V-VOLs other than DP-VOLs are used as pair volumes, this field remains blank.

Attribute

The attribute for a pair volume is displayed.

  • MTIR: MTIR pair

This field remains blank when the attribute is other than MTIR.

Update Type

One of the following:

  • Sync: It is a TC or TCz pair which is not assigned to consistency group.
  • Sync (Specified CTG): It is a TC or TCz pair created by specifying consistency group.

CTG ID

Consistency group identifier

CTG Utilization

Whether the consistency group is shared by multiple storage systems.

  • Single: The consistency group consists of a single pair of primary and secondary storage systems.
  • Multi: The consistency group consists of multiple storage systems.

Preserve Mirror Status (VSP 5000 series)

Preserve Mirror Status. A hyphen (-) is displayed for TC.

Fence Level

Whether the P-VOL can be written to when the pair is split due to error.

  • Data: The P-VOL cannot be written to.
  • Status: The P-VOL cannot be written to only if the primary system cannot change the S-VOL status to PSUE (TC) or Suspend (TCz). If the primary system cannot change the S-VOL status, the P-VOL cannot be written to.
  • Never: The P-VOL can be written to.

Host I/O Time Stamp Transfer (VSP 5000 series)

TCz only.

Specified time stamp transfer value.

Secondary Volume Write

Whether data can be written (Enabled) or not written (Disabled) to the S-VOL. The pair must be split for Enabled to display.

If the volume accessed is an S-VOL and can be written to, Enabled/Received or Enabled/Not Received is displayed. Indicates whether a write operation is received from the host or not.

Copy Pace

Speed that data is copied.

Initial Copy Priority

Scheduling order for the initial copy operation. The default is 32.

The range is 1 to 256 for TC. The range is 0 to 256 for TCz.(VSP 5000 series)

Paired Time

Date and time pair-creation was completed.

Last Update Time

Date and time that the last update was run.

Pair Copy Time

Elapsed time for paircreate or pairresync operation.

CFW Data (VSP 5000 series)

Whether CFW data is copied to the S-VOL as specified during pair creation. A hyphen (-) is displayed for TC pairs.

DFW to Secondary Volume (VSP 5000 series)

Whether the primary system splits the TCz pair when the secondary system cannot copy DFW data to the S-VOL. A hyphen (-) is displayed for TC pairs.

Local Storage System

  • Virtual storage machine: Virtual storage machine's model type and serial number.
  • Virtual LDEV ID: Virtual LDEV identifier of the volume.
  • Virtual Device Name: Virtual device name of the volume, in the format: virtual emulation type/number of virtual LUSE volumes/virtual CVS attribute.
    • Only attributes that are specified are displayed.
    • If the virtual CVS attribute is specified, "CVS" is displayed at the end of the device name.
    • A blank indicates no values are specified.
  • Virtual SSID: Virtual SSID of the volume. A blank indicates that no virtual SSID is specified.
