Mapping A Virtual Disk
After creating new virtual disks, use the Mappings tab to present the virtual disks to the ESX/ESXi host for use. From this
view, you can manage hosts, host groups and virtual disk mappings.
To present a new virtual disk to a host:
1. Click Add Mapping to start the wizard.
Figure 47. Virtual Disk Mapping View
2. Select the host or host group to map to the new virtual disk.
3. Select the virtual disk number for the virtual disk to be mapped.
4. Click OK.
NOTE: When your MD storage array uses multiple groups of HBAs per 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 is possible if this occurs.
After the virtual disks have been mapped to the host, the storage adapters on the host must be rescanned to detect
the new storage virtual disks using Hosts and Clusters view → Configuration → Storage Adapters for the host
being configured.
NOTE: You may need to run a rescan from vCenter twice to detect all of the new storage virtual disks mapped
to the host.
