Table 37 Path Status and Examples of the Recovery Procedure (AMS/WMS)

Path Status

Examples of the Recovery Procedure

 

 

External device setting

Settings of the LU paths may have been changed by LUN Manager. Check the

changed

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.

 

 

Illegal request or

The volume may have been set as a pair volume for data copy. Check if the

Response error

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.

 

 

Cannot detect port

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.

 

 

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.
