– Standby: The port of the external subsystem is standing by. The port status is normal
but cannot receive I/O.
– Target error: Port failures, such as controller blockade are detected on the external
subsystem 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.
– Device check error: The target volume in the external subsystem is not accessible,
even though the external volume was mapped.
– Medium error: The target volume in the external subsystem has become inaccessible.
◦ 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
To display the Port tree, select the Port tab. 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 .
