Table 33 Causes of Volume Discovery Failure and Required Actions (continued)
Cause
External volume is configured as a management LU.
Remote command devices of the external storage system are cascaded.
External storage system information that is retrieved by the port discovery is not found in the profile information.
Login to the external storage system failed.
External volume is not in the normal status. Or a failure or an error occurred in retrieving the information from the external storage system.
Action
If a management LU is configured on the port of the external storage system, perform one of the following:
•Make sure that at least one LU is used for data storage and has a smaller LUN than the LUN of the management LU. Also make sure that the data storage LU is set to the port connected to the local storage system.
•Delete the management LU from the port connected to the local storage system. operations.
•Use a security function and configure the access attribute of the management LU to prohibit read and write
Perform one of the following:
•Change the configuration so that the remote command devices are not cascaded.
•Use a security function or delete the LU setting from the port of the connected external storage system so that the local storage system cannot recognize the remote command devices.
Perform one of the following:
•Connect an external storage system supported by XP External Storage.
•Call HP technical support to ask if the external storage system is supported by XP External Storage. If the external storage system is supported, you can connect the external storage system by either installing the microcode version that supports the external storage system or the profile information for the external storage system.
Perform one of the following:
•Make sure that the port of the external storage system is in the normal status.
•Register WWN to the external storage system to allow login from the local storage system.
Make sure that the external storage system or the external volume is in the normal status.
If none corresponds to the actual factor, disconnect the cable between the local storage system and the external storage system once and connect it appropriately again. After 30 seconds, retry the operation.
Calling HP Technical Support
If you need to call HP technical support, be sure to provide as much information about the problem as possible. Include the circumstances surrounding the error or failure, the Remote Web Console configuration information saved in the floppy disks by the FD Dump Tool, the exact content of any messages displayed on the Remote Web Console, and the severity levels and reference codes displayed on the Status tab of the Remote Web Console main window.
