Problem
If a management LU, such as Universal Xport LU, is configured on
the external system port, perform one of the following:
The external volume is configured as a
management LU.
•
Make sure that at least one LU is used for data storage and has
a smaller LUN than the management LU’s LUN. Also make sure
that the data storage LU is set to the port connected to the local
system.
•
Delete the management LU from the port connected to the local
system.
•
Use a security function and configure the access attribute of the
management LU to prohibit read and write operations.
Perform one of the following:
Remote command devices of the external system
are cascaded.
•
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 system so that the local system cannot
recognize the remote command devices.
Perform one of the following:
External system information retrieved by port
discovery is not found in the profile information.
•
Connect an external system supported by External Storage.
•
Call the HP Technical Support to ask if the external system is
supported by External Storage. If the system is supported, install
the microcode version that supports the external system or install
the profile information of the external system.
Perform one of the following:
Login to the external system failed.
•
Make sure that the port of the external system is in Normal status.
•
Register the WWN to the external system to allow login from the
local system.
Make sure that the external system or the external volume is in the
Normal status.
The external volume is not in Normal status, or
a failure or error occurred in retrieving
information from the external system.
If none of the actions suggested in the table provide volume discovery, remove the cable connection
between the local and external storage systems, and then reconnect the storage systems. After 30
seconds, retry the operation.
