124 Troubleshooting
Description
The path has been removed or the port
of the external storage system cannot
be found. There is a problem with the
connection to the external storage
system. The possible causes are:
The fiber cable is not physically
connected in the proper way.
The setting of the topology does
not match between the external
port and the target port.
Because the security is set on the
port, the device of the external
storage system cannot be
recognized from the local storage
system.
If the external storage system is
connected through switches, the
settings for the switches may not
be appropriate.
The program error occurred. Or there
is a logical contradiction.
The processing was retried because
the abnormal reply (Response) was
returned, however, the processing has
been stopped by timeout.
An error such as the blockade of the
controller has been found in the port
of the external storage system.
The reply of the external storage
system was Unavailable. The external
storage system demands to change
the connected port. When the status
becomes Unavailable, the primary
path changes to the alternate path that
is in the Standby status. When the
primary path has been changed, the
status of the path becomes Normal.
The reply of the external storage
system was Backoff. The status of the
path is waiting for recovery because
a temporary error has occurred in the
volume of the external storage system.
Even if the status of the primary path
becomes this status, the primary path
is not changed to the alternate path
immediately. After the error recovery,
the status becomes Normal.
An external volume is mapped, but
you cannot access the volume in the
external storage system.
Action
If you cannot restore the path, call HP
technical support.
Check the condition of the connection
to the external storage system. If you
cannot restore the path, call HP
technical support.
Call HP technical support.
The port of the external storage system
is recognized. Check the condition of
the connection (for example, cables,
switches) to the external storage system.
If you cannot restore the path, call HP
technical support.
Check the status of the ports of the
external storage system. If you cannot
restore the path, call HP technical
support.
If the path is not changed over
properly, check the status of the
external storage system. If you cannot
restore the path, call HP technical
support.
If the status cannot be recovered from
the error, the path status changes to
another status. React to the new path
status after the status is changed. If you
cannot restore the path, call HP
technical support.
Check the status of the volume in the
external storage system and recover the
volume if it is not normal.
