HP StorageWorks User Manual

External Storage XP user guide 49
• LDEV Status: Mapped external LU’s status. Possible values: Normal, Unknown, Blockade, Warning,
or Format. For a description of these values, see Table 8.
• Product name of the connected external disk array
• WWN: WWN identifying the port in the external disk array for which the connection setting is
completed.
• Path: Number of set paths.
• I/O TOV: Value specified as the timeout for I/O to the external LU.
• Qdepth: Number of Read/Write commands that can be issued (queued) to the external LU at one
time.
• Path Watch: Time until the path is blocked after the connection to the external disk array goes
down.
• Mode: How alternate paths between the local disk array and external disk array work. Alternate
path modes include:
• Single: Uses only the path with the highest priority (primary path) to execute I/O to the external
LU. When an error occurs in the primary path, the path with the second highest priority is used.
• Multi: Uses all set paths at the same time to execute I/Os to the external LU, distributing the work
load.
• Status: Status of the path set in the port identified by the WWN. The highest emergency level status
appears when two or more paths are set. Statuses include:
• Normal: Path is normal.
• Unknown: Path status is unknown.
• Blockade: Path is blocked.
• Disconnect: Connection to the external disk array or external LU was intentionally stopped using
the Disconnect Subsystem or Disconnect Volume command.
• Warning: There are paths whose status is not normal. Check the status of the paths.
• Checking: Process of checking the paths’ defined configuration informations is in progress.
• WWN of the external disk array
• Port: Port number of the local disk array connected to the port identified by the WWN selected in
the Port tree.
• WWN: WWN of the external disk array selected in the Port tree.
• LUN: External disk array’s LU number.
• Characteristic: External LU’s identification number.
• 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 the
external LUs are mapped. This is displayed in the format of “external LU group number - reference
number of volume in the group”.
• Status: Status of the path configured by the port of the local disk array and the port of the external
disk array identified by the WWN. One of the following statuses is displayed:
• Normal: Path is normal.
• Unknown: Path status is unknown.
• Blockade: Path is blocked.
• External device setting changed: External disk array setting changed. For example, the path
definition was deleted, or the external disk array itself was replaced by another device.
• LDEV size reduced: External disk array’s volume capacity setting changed (volume capacity was
reduced).
• Not ready: External disk array replied NOTREADY.
• Illegal request: External disk array replied ILLEGALREQUEST.
• Command aborted: External disk array replied ABORTEDCOMMAND.
• Busy: External disk array is in BUSY status.
• LDEV reserved: External disk array is in Reserve status.
