Connecting XP1024/XP128 disk arrays

When connecting an XP 1024/XP128 disk array as the external disk 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.

Examples of recovery procedures
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, Continuous Access XP 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.
LUN Security XP Extension 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.
There is a problem with the 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 Management
to set the fibre channel port properly.
LUN Management may have enabled LUN security.
Check if LUN security is enabled. If LUN security is enabled, disable LUN
security.
"Troubleshooting External Storage
Examples of recovery procedures
LUN Manager 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
External Storage XP to perform the Delete LU operation, and perform the
Add LU operation again.
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.
