Examples of Recovery Procedure Path Status
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
subsystem. 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 subsystem 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 LUN Manager.
e LUN security may have been enabled by LUN Manager.
Check if the LUN security is enabled or not. If the LUN
security is enabled, disable the LUN security.
Connecting XP24000/XP20000 Disk Arrays
When you connect an XP24000 Disk Array or XP20000 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 port or the RCU target port.
Path status and examples of recovery procedure (for XP24000/XP20000 Disk Arrays)
Table 21 (page 150) shows the examples of the recovery procedure 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, call technical support.

Examples of recovery procedure Path status
Settings of the LU paths may have been changed by XP LUN Configuration and Security
Manager Software. Check the settings of the LU paths. If the settings of the LU paths have External device setting
changed
been changed, change the settings back to the ones when the volume is mapped. Or
use XP External Storage Software to perform the Delete Volume operation and perform
the Add Volume operation again.
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.
The volume may have been set as a pair volume for data copy. Check if the volume is
set as a pair volume of XP Business Copy Software, XP Continuous Access Synchronous, Illegal request
XP Continuous Access Journal or some other copy program. If the volume is set as a pair
volume, the volume may be protected because of the pair status. When the volume is
protected, change the pair status or delete the pair.
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.
The volume may have been set as a pair volume for data copy. Check if the volume is
set as a pair volume of XP Business Copy Software, XP Continuous Access Synchronous, Response error
XP Continuous Access Journal or some other copy program. If the volume is set as a pair
volume, the volume may be protected because of the pair status. When the volume is
protected, change the pair status or delete the pair.
