Table 46 Path Status and Examples of the Recovery Procedure (Lightning 9900)

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.

 

 

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.

 

 

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.

 

Make sure that the fiber cable is connected properly, and then set the Fibre

 

Channel port properly using LUN Manager.

 

The LUN security may have been set by LUN Manager. 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 connecting an 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.

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/XXor 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 mapping setting and then change the microcode version to the one that supports the SVS200 storage system.

Path Status and Examples of the 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 Table 47 (page 146) to recover the path status. For other errors not described in this section, see “Troubleshooting for XP External Storage” (page 126). If you cannot restore the path, call HP technical support (see “Calling HP Technical Support” (page 131)).
