changed • LU paths settings may have been changed by LUN Manager. Either change the settingsback to the values used when the volume was mapped, or perform the Delete LU and then Add LU operations using External Storage.
• The volume’s access attribute may have been changed by Data Retention. If the volume is protected by the access attribute, release the protection.
Illegal request or • If the volume is a pair volume, it may be protected because of the pair status. If this is the case, change the pair status or delete the pair.
Response error
• The volume’s access attribute may have been changed by Data Retention. If the volume is protected by the access attribute, release the protection.
Cannot detect port • There is a problem with connection to the external storage system. The possible causes are: - Make sure the fibre cable is connected correctly.
- The setting of the topology may not match between the external port and the target port. Make sure that the Fibre Channel ports are set properly using LUN Manager.
- If the external storage system is connected through switches, make sure that the switch settings are correct.
• The host group LUN security may have been enabled by LUN Manager. If so, disable it.

Troubleshooting port and volume discovery problems
The following table shows corrective actions you can take for port and volume discovery problems. Corrective action
Problem
Connect the External port of the local system and the external system port.
The port on the local storage system and port on the external system are not connected.
Connect the cable to the correct port on the switch. Or change the port status to the normal status.
The cable for the switch is not connected correctly, or the switch’s port is blocked.
Corrective action Problem
Make sure the zoning configuration is correct so that the External port of the local system can communicate with the external system port.
Zoning for the switch is not set appropriately.
Connect the external system to the External port of the local system. If necessary, change the local system port to “External”.
The external system is not connected to the External port on the local system.
Release the reserved state of the external volume. External volume returned RESERVATION
CONFLICT.
Cancel the port security setting or change the security of the external system so that the local system can access the port of the external system.
Port security is set on the external system.
Configure an LU on the port. No LU is configured on the external system port.
Perform one of the following: External volume capacity is less than the
supported capacity for External Storage. • Increase the external volume’s capacity to be equal or larger than the supported capacity.
• Use a security function or delete the LU setting from the external system port so that the local system cannot recognize a volume with insufficient capacity.
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.
