Mapping a Virtual Disk
After creating new virtual disks, use the Mappings tab to present the virtual disks to the ESX host for use. See .
From this view, you can manage hosts, host groups, and virtual disk mappings. To present a new virtual disk to
an ESX host, click the Add Mapping link to start the Add Mapping wizard.

Select the host group or host to which to map the new virtual disk.
2
Select the virtual disk number to use and virtual disk to be mapped.

Click OK
NOTE: When your storage array uses multiple groups of HBAs per ESX host, the new virtual disks should
be balanced across all hosts/host groups. Do not add all the virtual disks to a single host/host group; no
I/O balancing can occur in this case.
After the virtual disks have been mapped to the ESX host, the storage adapters on the ESX host must be
rescanned to detect the new storage virtual disks. This action is accomplished from Hosts and Clusters view >>
Configuration tab >> Storage Adapters for the ESX host being configured. See Figure 41.
NOTE: You may need to run the Rescan, from vCenter, twice to detect all of the new storage virtual
disks that have been mapped to the ESX host.
