Using Serviceguard Extension for RAC, 4th Edition, February 2007

Serviceguard Configuration for Oracle 10g RAC
Creating a Storage Infrastructure with CFS
Chapter 2 77
CAUTION Once you create the disk group and mount point packages, it is critical
that you administer the cluster with the cfs commands, including
cfsdgadm, cfsmntadm, cfsmount, and cfsumount. If you use the general
commands such as mount and umount, it could cause serious problems,
such as writing to the local file system instead of the cluster file system.
Any form of the mount command (for example, mount -o cluster,
dbed_chkptmount, or sfrac_chkptmount) other than cfsmount or
cfsumount in a HP Serviceguard Storage Management Suite
environment with CFS should be done with caution. These non-cfs
commands could cause conflicts with subsequent command operations on
the file system or Serviceguard packages. Use of these other forms of
mount will not create an appropriate multi-node package which means
that the cluster packages are not aware of the file system changes.
Deleting CFS from the Cluster
Halt the applications that are using CFS file systems.
1. Unmount CFS Mount Points
# cfsumount /cfs/mnt1
# cfsumount /cfs/mnt2
# cfsumount /cfs/mnt3
2. Delete Mount Point Multi-node Package
# cfsmntadm delete /cfs/mnt1
The following output will be generated:
Mount point “/cfs/mnt1” was disassociated from the
cluster
# cfsmntadm delete /cfs/mnt2
The following output will be generated:
Mount point “/cfs/mnt2” was disassociated from the
cluster
# cfsmntadm delete /cfs/mnt3
The following output will be generated:
