58 Adding and removing a node

Removing a node from a cluster

4

Remove 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

.

5

Write the new VCS configuration to disk:

# haconf -dump -makero

6

Edit

/etc/llthosts

on the remaining nodes of the cluster, and remove the

entry corresponding to the node being removed.

7

Edit

/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.

8

Login to system03 and remove the following files:

# rm /etc/vxfenmode

# rm /etc/llthosts

# rm /etc/llttab

# rm /etc/gabtab

9

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

# rm /etc/vxfentab

# rm /etc/vxfendg

10 If 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

-n

N option, where N is the number of

cluster systems. If the command has the form

/sbin/gabconfig

-c

-n

N,

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.

11 Change to the

install

directory:

# cd /opt/VRTS/install
