Modifying and Removing Host-to-Virtual Disk Mapping
You can modify or remove a host-to-virtual disk mapping for several reasons,
such as an incorrect mapping or reconfiguration of the storage array.
Modifying or removing a host-to-virtual disk mapping applies to both hosts
and host groups.
To modify or remove host to virtual disk mapping:
NOTE: Before you modify or remove a host-to-virtual disk mapping, stop any data
access (I/O) to the virtual disks to prevent data loss.
