Connecting XP1024/XP128 Disk Arrays
When connecting an XP1024/XP128 Disk Array as the external array, you must set the external
array port host group for one of two types of 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 (XP1024/XP128 Disk Arrays)
Table 22 on page 170 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 151 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.
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 to perform the Delete LU
operation, and perform the Add LU operation again.

XP LUN Security Extension Software 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.
Check if the volume is set as a pair volume for XP Business Copy, XP Continuous Access, 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.

There is a problem with connection to the external 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 array is connected through switches, the switches' settings might not be ap-
propriate.
Check if the fibre cable is connected properly, and use XP LUN Configuration and Security
Manager Software to set the Fibre Channel port properly.
