HP StorageWorks XP Remote Web Console Software - Manual (Page 88)

88 Configuring external LUs
• Port: Port number in the local array connected to the external array. One of the following icons
appears for each port:
• WWN: External array port’s identification number.
• LUN: LU number of the external LU.
• Priority: Priority of paths connecting to the external LU. A 1 indicates the path with the highest
priority.
• Status: Status of the path to the external LU. For information about reacting to the displayed status,
see ” Troubleshooting External Storage XP ” on page 121. Possible values:
• Normal: Path is normal.
• Unknown: Path status is unknown.
• Blockade: Path is blocked.
• External device setting changed: External array’s setting changed. For example, the path
definition was deleted or the external array itself was replaced.
• LDEV size reduced: External array’s volume capacity setting changed (volume capacity was
reduced).
• Not ready: External array replied NOTREADY.
• Illegal request: External array replied ILLEGALREQUEST.
• Command aborted: External array replied ABORTEDCOMMAND.
• Busy: External array status is BUSY.
• LDEV reserved: External array status is Reserve.
• Response error: External array status is blocked because of an abnormal reply (Response).
• Initiator port: External array’s port attribute changed to initiator port.
• RCU target port: External array’s port attribute changed to RCU target.
• Unknown port: External array’s port attribute is unknown.
• Cannot detect port: Path was removed or external array port could not be found.
• Internal error: Program error occurred, or there is a logical contradiction.
• Timeout: Processing was retried because of an abnormal reply, but a timeout occurred.
• 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, were detected on the external array side.
• Checking: External Storage XP is checking defined path configuration information.
• Disconnect: Connection to the external array or LU was stopped using the Disconnect Subsystem
or Disconnect Volume command.
• Unavailable: External array replied Unavailable. The external array demands to change the
connected port. After the status becomes Unavailable, the primary path changes to the alternate
path that is in the Standby status. When the primary path changes, the path status becomes
Normal.
• Backoff: External array replied Backoff. The path status is Waiting for Recovery because a
temporary error occurred in the external array’s volume. Even if the primary path’s status
becomes Backoff, the primary path does not change to the alternate path immediately. After the
error recovery, the status becomes Normal. If you cannot recover the status from the error, the
path status changes to the other status.
• I/O TOV: Time over value for I/O to the external LU
• Qdepth: Number of Read/Write commands that can be issued (queued) to an external LU at one
time
