External Storage XP user guide 135
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 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 121 and this table to recover the path
status. If you cannot restore the path, contact your HP account support representative.
Response error 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.
Cannot detect port 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 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.

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.
