Managing Serviceguard Eighteenth Edition, September 2010

NOTE: Because the CVM system multi-node package automatically starts up the
Veritas processes, do not edit /etc/llthosts, /etc/llttab, or /etc/gabtab.
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
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. You can verify the package creation with the cmviewcl command, or with the
cfsdgadm display command. An example of cfsdgadm output is shown below:
cfsdgadm display
Node Name : ftsys9 (MASTER)
DISK GROUP ACTIVATION MODE
logdata off (sw)
Node Name : ftsys10
DISK GROUP ACTIVATION MODE
logdata off (sw)
3. Activate the disk group and start up the package:
cfsdgadm activate logdata
