Storage System)
Path Status Examples of Recovery Procedure
External device setting
changed
Settings of the LU paths may have been changed by LUN Manager.
Check the settings of the LU paths. If the settings of the LU paths have been
changed, change the settings back to the ones when the volume is mapped.
Or use External Storage to perform the Delete LU operation and perform
the Add LU operation again.
Illegal request or
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 of Business Copy, Continuous
Access, or some other copy program. If the volume is set as a pair volume,
the volume may be protected because of the pair status. When the volume is
protected, change the pair status or delete the pair.
Cannot detect port
There is a problem with connection to the external storage system. The
following are possible causes:
• The fibre cable is not physically connected in the proper way.
• The setting of the topology does not match between the external port
and the target port.
• If the external storage system is connected through switches, the settings
for the switches may not be appropriate.
Check if the fibre cable is connected properly, and then set the Fibre Channel
port properly using LUN Manager.
The LUN security may have been set by Hitachi SANtinel.
Check if the LUN security is set or not. If the LUN security is set, remove the
setting of the LUN security.
SVS200 Storage System
When you connect a SVS200 storage system as the external storage system, you need to set the port to
the host group for the Windows hosts (host mode 0C: Windows, host mode 2C: Windows Extension).
Also, the port attribute must be the target port or the RCU target port.
Note: If you are using the microcode that does not support the SVS200 storage system, the SVS200
storage system is recognized as the XP12000 storage system. If you need the connected external storage
system to be recognized as the SVS200 storage system, use the microcode of the version that supports the
SVS200 storage system (which is the microcode version 50-07-0X-XX/XX or higher). If you have used
an earlier microcode version that does not support the SVS200 storage system to map the volumes of
the SVS storage system, delete the setting of mapping and then change the microcode version to the
one that supports the SVS200 storage system.
Path Status and Examples of Recovery Procedure (For SVS200 Storage System)
This section describes errors which requires recovery operation on the external storage system
side when the path status is not normal. When the path status is not normal, see the following
table to recover the path status. For the other errors which are not described in this section, see
“ Troubleshooting for External Storage ” on page 107. If you cannot restore the path, call HP technical
support.
