58Adding and removing a node

Removing a node from a cluster

4Remove system03 from the system list attribute of the CVM and SFCFS service groups:

#hagrp -modify service_group SystemList -delete system03

#hagrp -modify cvm SystemListf -delete system03

where service_group is the command that displays the service groups by hagrp -dep cvm.

If an error message similar to the following is displayed by either of the above commands:

VCS:10456:Configuration must be ReadWrite. (’hagrp

-modify ...

-delete(0x10f)’,Sysstate=RUNNING,Channel=IPM,Flags=0x0)

Repeat step 3 and the command that failed in step 4.

5Write the new VCS configuration to disk:

#haconf -dump -makero

6Edit /etc/llthosts on the remaining nodes of the cluster, and remove the entry corresponding to the node being removed.

7Edit /etc/gabtab on the remaining nodes of the cluster and edit the gabconfig command to reflect the correct and new number of nodes in the cluster.

8Login to system03 and remove the following files:

#rm /etc/vxfenmode

#rm /etc/llthosts

#rm /etc/llttab

#rm /etc/gabtab

9If fencing was enabled on the cluster, run the following commands:

#rm /etc/vxfentab

#rm /etc/vxfendg

10If necessary, modify the /etc/gabtab file. No change is required to this file if the /sbin/gabconfig command has only the argument -c, although Symantec recommends using the -nNoption, where N is the number of cluster systems. If the command has the form /sbin/gabconfig -c-nN, where N is the number of cluster systems, then make sure that N is not greater than the actual number of nodes in the cluster, or GAB does not automatically seed.

Modify /etc/llthosts file on each remaining nodes to remove the entry of the leaving node.

11Change to the install directory:

# cd /opt/VRTS/install
