Creating the Disk Groups
Initialize the disk group from the master node.
1. Find the master node using vxdctl or cfscluster status
2. Initialize a new disk group, or import an existing disk group, in
shared mode, using the vxdg command.
•For a new disk group use the init option:
vxdg -s init logdata c4t0d6
• For an existing disk group, use the import option:
vxdg -C -s import logdata
3. Verify the disk group. The state should be enabled and shared:
vxdg list
NAME STATE ID
logdata enabled, shared, cds 11192287592.39.ftsys9
NOTE If you want to create a cluster with CVM only - without CFS, stop here.
Then, in your application package’s configuration file, add the
dependency triplet, with DEPENDENCY_CONDITION set to
SG-DG-pkg-id#=UP and DEPENDENCY_LOCATION set to SAME_NODE. For
more information about these parameters, see “Package Parameter
Explanations” on page 287.
Creating the Disk Group Cluster Packages
1. Use the cfsdgadm command to create the package SG-CFS-DG-ID#,
where ID# is an automatically incremented number, assigned by
Serviceguard when it creates the package. In this example, the
SG-CFS-DG-ID# package will be generated to control the disk group
logdata, in shared write mode:
cfsdgadm add logdata all=sw
2. With Veritas CFS, you can verify the package creation with the
cmviewcl command, or with the cfsdgadm display command. An
example of cfsdgadm output is shown below:
