Integrations with Other Applications

MC/ServiceGuard Integration

1. On system2 set up the volume group to be imported, with the

	following steps:
	a. Create a directory for the volume group to be imported:
		mkdir /dev/vg_ob2cm
	b. List all existing volume groups on the system to look for the next
		available minor number:
		ll /dev/*/group
	c.	Create a group file for the volume group:
		mknod /dev/vg_ob2cm/group c 64 0x010000
	d. Import the volume group with map file /tmp/lvm_map:
		vgimport -m /tmp/lvm_map -v /dev/vg_ob2cm
		/dev/dsk/c0t1d0 /dev/dsk/c1t2d0
	2. Set volume group properties according to the cluster documentation,
	with the following steps:
	a. Mark the volume group for the cluster use:
		vgchange -c y /dev/vg_ob2cm
NOTE	If this is a cluster lock disk and you are using a later version of
	MC/ServiceGuard like 11.09, this is done automatically.

b. Use the volume group in the exclusive mode: vgchange -a e /dev/vg_ob2cm

3. Mount the logical volume to the mount point directory, with the following steps:

a. Create the same mount point directory as you have created on the Primary Cell Manager (/omni_shared):

mkdir /omni_shared

b. Mount the filesystem to the mount point directory: mount /dev/vg_ob2cm/lv_ob2cm /omni_shared

4. Configure the Secondary Cell Manager:
