Create a host group to be used by the S-VOL of the GAD pair. The requirement to create a host group depends on the host group ID used by the S-VOL:

When the host group ID used by the S-VOL is 0
The host group whose host group ID is 0 exists by default. Set a host mode to the host group (Windows host mode shown), as follows:
```
raidcom modify host_grp -port CL1-C-0 -host_mode WIN -IH1
```
Check command and output examples: Display the information about the host group that is set for the port (CL1-C), and confirm that the host mode is correct.
```
raidcom get host_grp -port CL1-C -IH1
PORT GID GROUP_NAME Serial# HMD HMO_BITs
CL1-C 0 1C-G00 822222 WIN
```
When the host group ID used by the S-VOL is 1 or higher
A host group whose host group ID is 1 or higher does not exist by default. Create a host group used by the S-VOL of the GAD pair, and set the host mode.

Note: If you create a new host group but do not reserve the new host group ID in the resource group, add the new host group ID to the resource group as described in Reserving a host group ID for a resource group (VSM manual configuration).

If you connect multiple server hosts of different platforms to a port, create a host group for each platform.

Creating a host group using VSM auto-configuration

Creating a host group using VSM manual configuration

Create a host group (HAVol) with host group ID 1 on port (CL1-C).
```
raidcom add host_grp -port CL1-C-1 -host_grp_name HAVol -IH1
```
Set the host mode for the new host group (Windows host mode shown).
```
raidcom modify host_grp -port CL1-C-1 -host_mode WIN -IH1
```
If you perform VSM manual configuration, reserve host group (CL1-C-1) to resource group HAGroup1.
```
raidcom add resource -resource_name HAGroup1 -port CL1-C-1 -IH1
```

Check command and output examples

Display the information about the host group that is set for port (CL1-C). Confirm that the port name, host group ID, and host group name are correct.

raidcom get host_grp -port CL1-C -IH1
PORT   GID  GROUP_NAME                       Serial# HMD          HMO_BITs
CL1-C    0  1C-G00                            822222 WIN
CL1-C    1  HAVol                             822222 WIN
