you cannot restore the path, contact your HP account support representative.
Table 23 Path status and examples of recovery procedures (XP512/XP48 Disk Arrays)
Path status
Examples of recovery procedures
External device setting changed 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.
Illegal request
Thevolumemayhavebeensetasapairvolumefordatacopy.
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.
Response error
Thevolumemayhavebeensetasapairvolumefordatacopy.
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.
There is a problem with 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
Hitachi SANtinel 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 External Storage XP connection) or “RCU target
port” (for a Continuous Access XP connection).
NOTE:
If you are using microcode that does not support the SVS200, the SVS200 is recognized as an XP12000
Disk Array. To recognize the connected external array as the SVS200, use the microcode version that
supports the SVS200 (which is microcode version 50-07-0X-XX/XX or higher). If you used an earlier
microcode version that does not support the SVS200 to map the SVS200 volumes, delete the mapping
setting, and then change the microcode version to the one that supports the SVS200.
