NOTE: If you are using disk arrays in RAID 1 or RAID 5 mode, omit the -m 1 and
-s g options.
Creating File Systems If your installation uses filesystems, create them next. 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
data, 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.
Deactivating the Volume Group At the time you create the volume group, it is active
on the configuration node (ftsys9, for example).The next step is to unmount the file
system and deactivate the volume group; for example, on ftsys9:
umount /mnt1
vgchange -a n /dev/vgdatabase
NOTE: Do this during this set-up process only, so that activation and mounting can
be done by the package control script at run time. You do not need to deactivate and
unmount a volume simply in order to create a map file (as in step 1 of the procedure
that follows).
Distributing the Volume Group Use the following commands to set up the same
volume group on another cluster node. In this example, the commands set up a new
volume group on ftsys10 which will hold the same physical volume that was available
on ftsys9. You must carry out the same procedure separately for each node on which
the volume group's package can run.
To set up the volume group on ftsys10, use the following steps:
1. On ftsys9, copy the mapping of the volume group to a specified file.
vgexport -p -s -m /tmp/vgdatabase.map /dev/vgdatabase
