110 External Storage XP for the XP12000/XP10000
Connecting XP512/XP48 disk arrays
When connecting an XP512/XP48 disk array as the external disk array, you must set the port’s host mode
to PC Server (0C).
Also, the port attribute must be the target or RCU target port.
Path status and examples of recovery procedures (XP512/XP48 disk arrays)
Table 22 shows examples of recovery procedures when the path status is not normal. When the path status
is not normal, see ”Troubleshooting External Storage XP” on page 95 and this table to recover the path
status. If you cannot restore the path, contact your HP account support representative.
Illegal request The volume may have been set as a pair volume for data copy.
Check if the volume is set as a pair volume for Business Copy XP,
Continuous Access XP, or another copy program. If the volume is set as a
pair volume, the volume might be protected because of the pair status. If
the volume is protected, change the pair status or delete the pair.
Open LDEV Guard may have changed the volume’s access attribute.
Check the volume’s access attribute. If the volume is protected by the
access attribute, release the protection.
Response error The volume may have been set as a pair volume for data copy.
Check if the volume is set as a pair volume for Business Copy XP,
Continuous Access XP, or another copy program. If the volume is set as a
pair volume, the volume might be protected because of the pair status. If
the volume is protected, change the pair status or delete the pair.
Open LDEV Guard may have changed the volume’s access attribute.
Check the volume’s access attribute. If the volume is protected by the
access attribute, release the protection.
Cannot detect port There is a problem with connection to the external disk array. The following
are possible causes:
• The fibre cable is not connected properly.
• The topology setting between the external and target ports does not
match.
• If the external disk array is connected through switches, the switches’
settings might not be appropriate.
Check if the fibre cable is connected properly, and use LUN Manager to set
the fibre channel port properly.
LUN Manager may have set LUN security.
Check if LUN security is enabled. If LUN security is enabled, disable LUN
security.

Add LU operation again.
