Managing Disk Groups and Mount Points Using Legacy Packages
To manage disk groups and mount points in a Serviceguard cluster using CVM/CFS, create disk
group and mount point packages. These packages are configured for activating disk groups and
mounting the volumes. The applications that use CVM/CFS require the disk group and mount point
packages to be up and running.
Creating a File System and Mount Point Package
1. Create a file system:
newfs -F vxfs /dev/vx/rdsk/logdata/log_files
version 6 layout
1-048576 sectors, 1048576 blocks of size 1024, log size 16384 blocks
largefiles supported
2. Create the cluster mount point:
cfsmntadm add logdata log_files /tmp/logdata/log_files all=rw
Package name “SG-CFS-MP-1” is generated to control the resource.
You do not need to create the directory. The command creates one on each of the nodes,
during the mount.
3. Verify with cmviewcl or cfsmntadm display. This example uses the cfsmntadm
command:
cfsmntadm display
Cluster Configuration for Node: ftsys9
MOUNT POINT TYPE SHARED VOLUME DISK GROUP STATUS
/tmp/logdata/log_files regular log_files logdata NOT MOUNTED
Cluster Configuration for Node: ftsys10
MOUNT POINT TYPE SHARED VOLUME DISK GROUP STATUS
/tmp/logdata/log_files regular log_files logdata NOT MOUNTED
4. Mount the file system:
cfsmount /tmp/logdata/log_files
This starts up the multi-node package and mounts a cluster-wide file system.
5. Verify that multi-node package is running and file system is mounted:
cmviewcl
CLUSTER STATUS
cfs_cluster up
NODE STATUS STATE
ftsys9 up running
ftsys10 up running
MULTI_NODE_PACKAGES
PACKAGE STATUS STATE AUTO_RUN SYSTEM
SG-CFS-pkg up running enabled yes
SG-CFS-DG-1 up running enabled no
SG-CFS-MP-1 up running enabled no

6. To view the package name that is monitoring a mount point, use the cfsmntadm
show_package command:
cfsmntadm show_package /tmp/logdata/log_files
