Item

Description

Cascade

Indicates whether a cascaded pair can be created

•

Enabled

 Cascaded pairs can be created.

•

Disabled

 Cascaded pairs cannot be created.

T10 PI*

The P-VOL's T10 PI attribute information.

•

Enabled

 The P-VOL's T10 PI attribute is enabled.

•

Disabled

 The P-VOL's T10 PI attribute is disabled.

Virtual Storage Machine*

Information about the virtual storage machine to which the P-VOL
belongs.

Values:

•

Model/Serial Number

 The model type and serial number of the P-

VOL’s virtual storage machine.

•

LDEV ID

 The identification number of the P-VOL’s virtual LDEV. If

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

•

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.

•

SSID

 The virtual SSID of the P-VOL. If no virtual SSID is specified,

a blank is displayed.
