External Storage XP user guide 59
• LDEV Status: Mapped external LU’s status. Possible values: Normal, Unknown, Blockade, Warning,
and Format.
• Product name of the connected external array
• ExG: External LU group number. This appears when you group the LUs from one or more external
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 8.
• LDEV Status: Mapped external LU’s status. Possible values: Normal, Unknown, Blockade, Warning,
and Format. For a description of these values, see Table 9.
• 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 LUN Security XP 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 LU
attributes set by mapping” on page 20.
• Cache Mode: Cache mode: Enable or Disable. For more information, see ”External LU attributes set
by mapping” on page 20.
• 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. External Storage XP automatically assigns reference numbers to LUs in the group when
external LUs are mapped. This appears in the format “external LU group number - reference
number of the LU in the group”.
Warning FC path or paths have an abnormal status. Check the status of the paths.
Checking External Storage XP is verifying configuration information defined for FC paths.
Cache Destage External Storage XP is writing all data in the local array cache memory to the LU.
Disconnect Connection to external array or external LU was intentionally stopped using the
Disconnect Subsystem or Disconnect Volume command.
Table 9 Mapped external LU status values
LDEV status Description
Normal LDEV status is normal.
Unknown LDEV status has yet to be ascertained.
Blockade I/O traffic to the LDEV is not permitted.
Warning External LUs have abnormal status.
Format Volume is in the process of being formatted.
