Changing the VxVM or CVM Storage Configuration

3.Edit clconfig.ascii and delete the line(s) specifying the NIC name and its IP address(es) (if any) from the configuration.

4.Run cmcheckconf to verify the new configuration.

5.Run cmapplyconf to apply the changes to the configuration and distribute the new configuration file to all the cluster nodes.

6.Runolrad -dto remove the NIC.

Changing the LVM Configuration while the Cluster is Running

You can do this in Serviceguard Manager, or use HP-UX commands as in the example that follows.

NOTE: If you are removing a volume group from the cluster configuration, make sure that you also modify any package that activates and deactivates this volume group. In addition, you should use the LVM vgexport command on the removed volume group; do this on each node that will no longer be using the volume group.

From the LVM’s cluster, follow these steps:

1.Use the cmgetconf command to store a copy of the cluster's existing cluster configuration in a temporary file. For example: cmgetconf clconfig.ascii

2.Edit the file clconfig.ascii to add or delete volume groups.

3.Use the cmcheckconf command to verify the new configuration.

4.Use the cmapplyconf command to apply the changes to the configuration and distribute the new binary configuration file to all cluster nodes.

NOTE: If the volume group that you are deleting from the cluster is currently activated by a package, the configuration will be changed but the deletion will not take effect until the package is halted; thereafter, the package will no longer be able to run without further modification, such as removing the volume group from the package configuration file or control script.
