Connecting XP12000/XP10000 disk arrays

When connecting an XP12000/XP10000 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
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 Manager to
set the fibre channel port properly.
LUN Manager may have enabled the host group security.
Check if host group security is enabled. If host group security is enabled,
disable host group 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.
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.
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.
