subsystems)
Path status 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.
External device setting changed
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.
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, 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.
Illegal request
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.
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, or another copy program. If the volume is set as

There is a problem with the 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 appropriate.
Check if the fibre cable is connected properly, and use LUN Manager
to set the Fibre Channel port properly.
Cannot detect port
LUN Manager may have enabled host group security.
Check if host group security is enabled. If host group security is
enabled, disable host group security.
