3. Check whether there are already volume groups defined on this
node. Be sure to give each volume group a unique name.
vgdisplay
4. Create separate volume groups for each Serviceguard package you
will define. In the following example, the LUNs /dev/cciss/c0d1p1
and /dev/cciss/c0d2p1, which are defined earlier as physical
volumes, are added to volume group vgpkgA and
/dev/cciss/c0d3p1 is added to vgpkgB:
vgcreate /dev/vgpkgA /dev/cciss/c0d1p1 /dev/cciss/c0d2p1
vgcreate /dev/vgpkgB /dev/cciss/c0d3p1
Figure 5-1 shows these two volume groups as they are constructed
for the MSA500 Storage.
