Setting up Policy Master I/0 fencing

The procedures in this section apply to production environments, where the
Policy Master database is on shared storage.

Setting up and testing the coordinator disks

This section assumes that your Policy Master cluster includes coordinator disks
that support SCSI-3 persistent reservations and I/O fencing.
See

Adding shared storage and testing disks for SCSI-3 compliance
"Adding storage devices" on page 98, and
Create a disk group with a single disk. For example, enter the following:
vxdg init vxfencoorddg sdA
Where vxfencoorddg is the name of the disk group, and sdA is the name
of the disk.
Add the other disks to the disk group. For example, enter the following:
vxdg -g vxfencoorddg adddisk sdB
vxdg -g vxfencoorddg adddisk sdC
Where sdB and sdC are the names of the disks.
Make sure the two systems are connected to the same storage devices you
are testing.
Start vxfentsthdw. Enter the following. If you are not using ssh, omit the -n
option:
vxfentsthdw -n -c vxfencoorddg
Provide the system information at the prompts. The utility reports its
progress on each disk in the disk group.
