Settings of the LU paths may have been changed by LUN Management. 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.
The access attribute of the volume may have been changed by Data Retention. Check
the access attribute of the volume. If the volume is protected by the access attribute,
release the protection.
The volume may have been set as a pair volume for data copy. Check if the volume is

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.
The access attribute of the volume may have been changed by Data Retention. Check
the access attribute of the volume. If the volume is protected by the access attribute,
release the protection.
There is a problem with connection to the external storage system. The possible causes
are:
Cannot detect port
•
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.
Make sure that the Fibre cable is connected properly, and then set the Fibre Channel
port properly using LUN Management.
The host group security may have been enabled by LUN Management. Check if the host
group security is enabled or not. If the host group security is enabled, disable the host
group security.
P9500 storage system
When connecting a P9500 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.
Path status and examples of recovery procedure
This section describes errors that require 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. If you cannot restore the path, call HP Technical Support (see
and other resources” (page 66)
).
