The access attribute of the volume may have been changed by Data Retention Utility.
Check the access attribute of the volume. If the volume is protected by the access attribute,
release the protection.
There is a problem with connection to the external array. The following are possible
causes: Cannot detect port
•
The fibre 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.
•
If the external array is connected through switches, the settings for the switches may
not be appropriate.
Check if the fibre cable is connected properly, and then set the Fibre Channel port
properly using XP LUN Configuration and Security Manager Software.
The LUN security may have been enabled by the XP LUN Configuration and Security
Manager Software.
Check if the LUN security is enabled or not. If the LUN security is enabled, disable the
LUN security.
Connecting XP12000/XP10000 Disk Arrays
When connecting an XP12000/XP10000 Disk Array as the external array, you need to set the
port to the host group for the Windows hosts (host mode 0C: Windows, host mode 2C: Windows
Extension).
Also, the port attribute must be the target or RCU target port.
Path status and examples of recovery procedures (XP12000/XP10000 Disk Arrays)
“Path status and examples of recovery procedures (XP12000/XP10000 Disk Arrays)” (page 151)
shows examples of recovery procedures when the path status is not normal. When the path status
is not normal, see
“Troubleshooting External Storage XP” (page 134) and this table to recover the
path status. If you cannot restore the path, contact technical support.

XP LUN Configuration and Security Manager Software
may have changed the LU paths' settings. External device setting changed
Check the LU paths' settings. If the LU paths' settings
changed, change the settings back to the ones used when
the volume was mapped. Or use XP External Storage
Software to perform the Delete LU operation, and perform
the Add LU operation again.
Data Retention Utility 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.
The volume may have been set as a pair volume for data
copy. Illegal request
Check if the volume is set as a pair volume for XP Business
Copy Software, XP Continuous Access Synchronous, XP
Continuous Access Journal, 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.
