Because the LUN assignments change, the storage array is to any running the host-agent software (if they are using the changed LUN assignments).
To reestablish a connection to the storage array, find a responsive management path (for example, one that can still detect the storage array), change the LUN assignments back, and reboot the host. If there is no responsive management path, you must reboot the host so the host-agent recognizes the default LUN assignment for the .
On some operating systems it is necessary to create a partition, run , and start and stop the host-agent software to re-create the access virtual disk. After this is done, delete and then add the host in the Enterprise Management Window to re-estabilish communication with the storage array.
