Managing Serviceguard Eighteenth Edition, September 2010

TIP: Set the logical volume timeout to an integral multiple of any timeout assigned
to the underlying physical volumes. Otherwise, the actual duration of the I/O request
can exceed the logical volume timeout. For details on how to change the I/O timeout
value on a physical volume, see the manpage for pvchange (1m).
Creating File Systems
If your installation uses filesystems, create them next.
NOTE: You can create filesystems by means of the cmpreparestg (1m) command.
See “Using Easy Deployment Commands to Configure the Cluster” (page 211) for more
information. If you use cmpreparestg, you can skip the procedure that follows, and
proceed to “Making Physical Volume Group Files Consistent” (page 238).
Use the following commands to create a filesystem for mounting on the logical volume
just created.
1. Create the filesystem on the newly created logical volume:
newfs -F vxfs /dev/vgdatabase/rlvol1
Note the use of the raw device file for the logical volume.
2. Create a directory to mount the disk:
mkdir /mnt1
3. Mount the disk to verify your work:
mount /dev/vgdatabase/lvol1 /mnt1
Note the mount command uses the block device file for the logical volume.
4. Verify the configuration:
vgdisplay -v /dev/vgdatabase
Distributing Volume Groups to Other Nodes
After creating volume groups for cluster packages, you must make them available to
any cluster node that will need to activate the volume group. The cluster lock volume
group must be made available to all nodes.
