Path status and examples of recovery procedures (XP512/XP48 Disk Arrays)
“Path status and examples of recovery procedures (XP512/XP48 Disk Arrays)” (page 154) shows
examples of recovery procedures when the path status is not normal. When the path status is not
normal, see
“Troubleshooting External Storage XP” (page 134) and this table to recover the path
status. If you cannot restore the path, contact technical support.

XP LUN Configuration and Security Manager Software
may have changed the LU paths' settings. External device setting changed
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 XP External Storage to
perform the Delete LU operation, and perform the Add LU
operation again.
The volume may have been set as a pair volume for data
copy. Illegal request
Check if the volume is set as a pair volume for XP Business
Copy, XP Continuous Access, 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.
The volume may have been set as a pair volume for data
copy. Response error
Check if the volume is set as a pair volume for XP Business
Copy, XP Continuous Access, 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.
There is a problem with connection to the external array.
The following are possible causes: Cannot detect port
•
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 XP
LUN Configuration and Security Manager Software to set
the Fibre Channel port properly.
Hitachi SANtinel for z/OS may have set LUN security.
Check if LUN security is enabled. If LUN security is
enabled, disable LUN security.
Connecting HP 200 Storage Virtualization System as external storage
When connecting an HP 200 Storage Virtualization System (SVS200) as the external array, you
must set the SVS200 port to a host group for Windows hosts (host mode 0C: Windows or host
mode 2C: Windows Extension).
Also, the SVS200 port attribute must be “target” (for an XP External Storage connection) or “RCU
target port” (for an XP Continuous Access connection).
