Sample Configuration
In this example, the volumes /dev/vg01/hb_vol1, /dev/vg01/hb_vol2, and /dev/vg01/hb_vol3 have service group heartbeat regions beginning at block 64 for service group groupz. The device /dev/vg01/hb_vol1 has a second heartbeat region beginning at block 192 for service group groupy.
The AllOrNone attribute is set to 0 for sghb1, specifying that the service group can come online with ownership of two disks.
