A storage unit is uniquely identified by a combination of the IP address of processor card 1, the IP address of processor card 2, and the storage unit machine type and serial number. The values that you supplied for this service operation do not match the values of a previously defined storage unit.
Ensure that you submit the correct values for the IP addresses of the processor cards and the machine type and serial number of the storage unit. Ensure that the storage unit that you are attempting to access is defined and online. Check the cables and IP connection between the management console and the storage unit. Restart the management console. If the problem persists, contact IBM technical support for assistance.
