HP XP External Storage Software - Manual (Page 110)

Error Corrective Action
- Unavailable
Status: The reply of the external storage system was Unavailable.
The external storage system demands to change the connected
port. Once the status becomes Unavailable, the primary path
is changed to the alternate path that is in the Standby status.
When the primary path has been changed, the status of the
path becomes Normal.
Reaction: 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.
- Backoff
Status: 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.
Reaction: If the status cannot be recovered from the error, the
path status is changed to another status. React to the new path
status after the status is changed. If you cannot restore the path,
call HP technical support.
The volume in the
external storage
system cannot be
found even after
the Port Discovery
or the Volume
Discovery was
performed.
Remove the error and retry the operation.
The factor of the error could be as follows:
• Remote Web Console is not in the Modify mode.
• Port of the local storage system and the port of the external storage system
are not connected.
• Port security is set on the external storage system.
• The device in the external storage system is not in the Normal status.
• External storage system is not connected to the port set to External of the local
storage system.
• The capacity is not enough (capacity is less than about 38 MB (77,760 blocks)).
• The cable for the switch is not connected appropriately.
• The zoning for the switch is not set appropriately.
If none of the above corresponds to the actual factor, disconnect the cable
between the storage system and the external storage system once and connect it
appropriately again. After 30 seconds, retry the operation.
The external volume
is blocked.
Remove the error and retry the operation.
The factor of the error could be as follows:
• All the set paths are blocked (paths are not connected).
• The attribute of external volume is not set to Read/ Write attribute.
• The external volume is blocked by error.
The Check Paths &
Restore Volume
command is
executed and you
have waited more
than 10 minutes,
but the status of
the device does
not change from
Checking.
Click Refresh ( ) command on the Remote Web Console main window while the
Status button is depressed. If the device status remains as Checking even though
you have updated the information, execute the Check Paths & Restore Volume
command again.
If the same problem persists despite retrying, call HP technical support.
