HP Serviceguard Extension for RAC (SGeRAC) manual Using CVM 5.x or later, # cmapplyconf -C clm.asc

Using CVM 5.x or later

This section has information on how to set up the cluster and the system multi-node package with CVM—without the CFS filesystem, on HP-UX releases that support them. See “About Veritas CFS and CVM from Symantec” (page 15).

Preparing the Cluster and the System Multi-node Package for use with CVM 5.x or later

The following steps describe how to prepare the cluster and the system multi-node package with CVM 5.x or later only.

1.Create the cluster file.

#cd /etc/cmcluster

#cmquerycl -C clm.asc -n ever3a -n ever3b

Edit the cluster file.

2.Create the cluster.

# cmapplyconf -C clm.asc

•Start the cluster.

#cmruncl

#cmviewcl

The following output will be displayed:

CLUSTER STATUS

ever3_cluster	up
NODE	STATUS	STATE
ever3a	up	running
ever3b	up	running

3.Configure the Cluster Volume Manager (CVM).

To configure and start the CVM stack, you need to configure the system multi-node package, SG-CFS-pkg. The SG-CFS-pkgdoes not restrict heartbeat subnets to a single subnet and supports multiple subnets.

Use the cmapplyconf command:

#cmapplyconf -P /etc/cmcluster/cfs/SG-CFS-pkg.conf

#cmrunpkg SG-CFS-pkg

When CVM starts, it selects a master node. From this node, you must issue the disk group configuration commands. To determine the master node, issue the following command from each node in the cluster:

#vxdctl -c mode

The following output will be displayed:

mode: enabled: cluster active SLAVEmaster: ever3b

or

mode: enabled: cluster active MASTERmaster: ever3b

•Converting disks from LVM to CVM.

Use the vxvmconvert utility to convert LVM volume groups into CVM disk groups. Before you can do this, the volume group must be deactivated, which means that any package
