HP XP External Storage Software - Manual (Page 76)

• Not ready: External array replied NOTREADY.
• Illegal request: External array replied ILLEGALREQUEST.
• Command aborted: External array replied ABORTEDCOMMAND.
• Busy: External array is in BUSY status.
• LDEV reserved: External array is in Reserve status.
• Response error: External array is in blocked status caused by an abnormal reply (Response).
• Initiator port: External array's port attribute changed to the initiator port.
• Unknown port: External array's port attribute is unknown.
• Cannot detect port: Path was removed or external array's port could not be found.
• Internal error: Program error occurred, or there is a logical contradiction.
• Timeout: Processing was retried because an abnormal reply (Response) was returned;
however, processing was stopped by a timeout.
• Standby: External array's port is standing by. Port status is normal, but cannot receive I/O.
• Target error: Port failures, such as controller blockade, are detected on the external array
side.
• Checking: Process of checking the paths' defined configuration information is in progress.
• Disconnect: Connection to the external array or external LU was intentionally stopped using
the Disconnect Subsystem or Disconnect Volume command.
• Unavailable: External array replied Unavailable. The external array demands to change
the connected port. Once the status becomes Unavailable, the primary path changes to
the alternate path that is in the Standby status. When the primary path changes, the status
of the path becomes Normal.
• Backoff: External array replied Backoff. The path status is waiting for recovery because a
temporary error occurred in the external array's LU. Even if the primary path's status becomes
Backoff, the primary path does not immediately change to the alternate path. After the error
recovery, the status becomes Normal. If the status cannot be recovered from the error, the
path status changes to the other status.
• 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) .
Port tree
When you select the Port tab, this tree displays information about ports that have the External attribute.
The contents displayed in the Port list changes depending on the item selected in the Port tree. For
instructions on setting the port attribute, see
Setting a local array's port attributes .
