Examples of recovery procedure

Path status

Make sure that the Fibre cable is connected properly, and then set the Fibre Channel port
properly using LUN Manager.

The LUN security may have been enabled by LUN Manager. Check if the LUN security is
enabled or not. If the LUN security is enabled, disable the LUN security.

XP12000 Disk Array/XP10000 Disk Array

When connecting a XP12000 Disk Array/XP10000 Disk Array 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.

Setting the host mode option for a volume larger than 2 TB (XP12000 Disk
Array/XP10000 Disk Array)

If a volume that has the capacity of more than 2 TB is mapped as an external volume, host mode
option No. 24 must be enabled. If No. 24 is disabled, a volume that has the capacity of more
than 2 TB cannot be mapped as an external volume. For instructions on setting the host mode
option, see the HP XP LUN Configuration and Security Manager User Guide: HP XP12000 Disk
Array, HP XP10000 Disk Array, HP 200 Storage Virtualization System
.

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

“Support

and other resources” (page 66)

).

Array)

Examples of recovery procedure

Path status

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

External device setting
changed

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 set as
a pair volume of Business Copy, Continuous Access Synchronous, Continuous Access Journal

Illegal request or

Response error

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.

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 the 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.
