the pair status or delete the pair.

Illegal request or

Response error

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 host group security may have been enabled by LUN Manager. Check if

the host group security is enabled or not. If the host group security is enabled,

disable the host group security.

USP V/VM Storage System

When connecting a USP V/VM 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.
