Connecting EVA arrays

Identifying logical volumes of EVA arrays (using Characteristic 2)

When the connected external array is an EVA array, LUNs are displayed as Characteristic in External
Storage XP's panes.

Examples of Recovery Procedure
• LUN Manager might have changed the LU paths' settings.
Check the LU paths' settings. If the LU paths' settings changed, change
the settings back to the ones 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 might 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 might have been set as a pair volume for data copy.
Check if the volume is set as a pair volume of Business Copy XP,
Continuous Access XP, Continuous Access XP Journal, or some other
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 might 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 might have been set as a pair volume for data copy.
Check if the volume is set as a pair volume of Business Copy XP,
Continuous Access XP, Continuous Access XP Journal, or some other
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 might 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 connection to the external array. The following
are possible causes:
• The fibre cable is not physically connected properly.
• The topology setting does not match between the external and
target ports.
• If the external array is connected through switches, the switches'
settings might not be appropriate.
Check if the fibre cable is connected properly, and then set the Fibre
Channel port properly using LUN Manager.
• LUN Manager might have enabled LUN security.
Check if the LUN security is enabled or not. If LUN security is enabled,
disable LUN security.
