DescriptionLDEV status

Volume is in the

process of being

formatted.

Format

• Product name of the connected external array

• ExG: External LU group number. This appears when you group the LUs from one or more ex-

ternal arrays under a common number.

• Serial: Product serial number.

• Product: Product name.

• Vendor: Vendor name.

• Ex-Dev. Status: Status of the operation executed on the external array, or status of the path

connection. Possible values: Normal, Unknown, Blockade, Warning, Checking, Cache Destage,

and Disconnect. For a description of these values, see Table 7.

• LDEV Status: Mapped external LU's status. Possible values: Normal, Unknown, Blockade,

Warning, and Format. For a description of these values, see Table 8.

• External LU group number

• Characteristic: External LU's identification number.

• Device: External LU's device name.

• Capacity: External LU's capacity in 512-byte blocks.

• Ex-Dev. info.: External array information. When the external array is an XP1024/XP128 or

TagmaStore Workgroup Modular Storage (WMS) array, an asterisk (*) appears.

• VMA: Information about the VMA setting by XP LUN Security Extension. When VMA is set for

the volume, an asterisk (*) appears.

• Alter. Path: Number of configured paths in the format The number of valid paths (the number

of primary alternate paths).

• IO Suppression: I/O Suppression mode: Enable or Disable. For more information, see External

• Cache Mode: Cache mode: Enable or Disable. For more information, see External LU attributes

set by mapping.

• Path: When paths are set, an asterisk (*) appears.

• Group: External LU group number and reference number assigned to each LU in the external

LU group. XP External Storage automatically assigns reference numbers to LUs in the group

when external LUs are mapped. This appears in the format “external LU group number - refer-

ence number of the LU in the group”.

• Ex-Dev. Status: Status of the operation executed to the external array, or status of the path

connection. Possible values: Normal, Unknown, Blockade, Warning, Checking, Cache Destage,

and Disconnect. For a description of these values, see Table 7.

• LDEV Status: Mapped external LU's status. Possible values: Normal, Unknown, Blockade,

Warning, and Format. For a description of these values, see Table 8.

• Progress: When Status is Cache Destage, displays the write process progress, from 1% to

100%.

• Characteristic2: External LU's extended identifying information. This information is used for

identifying logical volumes in the EVA array. For more information, see Identifying logical

volumes of EVA arrays (using Characteristic 2).

• Discovery

• WWN: World Wide Name identifying the port in the external array that can be set.
