Managing Serviceguard 13th Edition, February 2007

Building an HA Cluster Configuration
Creating the Storage Infrastructure and Filesystems with LVM and VxVM
Chapter 5 219
# mkdir /logs
3. Mount the volume:
# mount /dev/vx/dsk/logdata/log_files /logs
4. Check to make sure the filesystem is present, then unmount the
filesystem:
# umount /logs
Deporting Disk Groups
After creating the disk groups that are to be used by Serviceguard
packages, use the following command with each disk group to allow the
disk group to be deported by the package control script on other cluster
nodes:
# vxdg deport <DiskGroupName>
where <DiskGroupName> is the name of the disk group that will be
activated by the control script.
When all disk groups have been deported, you must issue the following
command on all cluster nodes to allow them to access the disk groups:
# vxdctl enable
Re-Importing Disk Groups
After deporting disk groups, they are not available for use on the node
until they are imported again either by a package control script or with a
vxdg import command. If you need to import a disk group manually for
maintenance or other purposes, you import it, start up all its logical
volumes, and mount filesystems as in the following example:
# vxdg import dg_01
# vxvol -g dg_01 startall
# mount /dev/vx/dsk/dg_01/myvol /mountpoint
NOTE Unlike LVM volume groups, VxVM disk groups are not entered in the
cluster ASCII configuration file, and they are not entered in the package
ASCII configuration file.
