restore the path to the external array according to the troubleshooting procedure. Then execute
the Check Paths & Restore Vol. command to make the external LU in Blockade status usable. If the
external LU's status remains Blockade, even though you restored the path to the external array and

the volume.

the external array's status to be usable, even though you execute the LDEV Restore command.

You can also restore the external LU by executing the Restore command on the LDEV

Information window. For more information, see
