Table 37 Path Status and Examples of the Recovery Procedure (AMS/WMS)
Examples of the 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 ones when the volume is mapped. Or use XP
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
Utility. Check the access attribute of the volume. If the volume is protected by
the access attribute, release the protection.
External device setting
changed
The volume may have been set as a pair volume for data copy. Check if the
volume is set as a pair volume of XP Business Copy, XP Continuous Access or
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
Utility. Check the access attribute of the volume. If the volume is protected by
the access attribute, release the protection.
Illegal request or
Response error
There is a problem with the connection to the external storage system. The
possible causes are:
•
The fiber 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.
Verify the fiber cable is connected properly, and then set the Fibre Channel
port properly using LUN Manager.
If host group security is enabled, disable host group security using LUN
Manager.
Cannot detect port
P9500 Disk Array
When connecting a VSP 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, contact HP.
