Creating a Host Group
A host group is a logical entity of two or more hosts that share access to
specific virtual disks on the storage array.
To create host groups:

2 In the Topology pane, select the storage array or the default group.
3 Perform one of the following actions:
Select Mappings Define Host Group.
Right-click the storage array or Default Group and select Define
Host Group from the pop-up menu.
4 Type the name of the new host group in the Enter New Host Group Name
field.
5 Select the appropriate hosts in the Select Hosts to Add Area field and click
Add.
6 Click OK. The host group is added to the storage array.
Creating Disk Groups and Virtual Disks
In some cases, the virtual disks may have been bound when the system was
shipped. However, it is important that you install the management software
and verify that the desired virtual disk configuration exists.
You can manage your virtual disks remotely using PowerVault Modular Disk
Storage Manager. A minimum of one virtual disk is required for an
active/passive cluster configuration and at least two virtual disks are required
for an active/active cluster configuration.
Disk groups are created in the non-configured capacity of a storage array and
virtual disks are created in the free capacity of a disk group. The hosts
attached to the storage array read and write data to the virtual disks.
NOTE:
Before you create virtual disks, you must first organize the physical disks
into disk groups and configure host access. You can then create virtual disks within
a disk group.
