HP StorageWorks External Storage XP user guide for the XP12000, XP10000, SVS200 (T1706-96009, October 2007)

• 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 configurationinformationisinprogress.
• 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).

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.
