You can use the vxassist command to use the host disk class for storage allocation. The host class specifies the host from which to allocate storage. The host class only applies to disk groups configured for FSS.

The host disk class instance is the same as the host name from the Cluster Server (VCS) configuration file, which can be displayed using the vxclustadm nidmap command.

Mirrored volumes can be created with mirrors across hosts using the host disk class using the mirror=host parameter:

# vxassist -g mydg make vol1 10g host:vm240v5 host:vm240v6

# vxassist -g mydg make vol1 10g mirror=host
