56 Adding and removing a node
Configuring SFCFS and CVM agents on the new node
Configuring SFCFS and CVM agents on the new node
You must configure the SFCFS and CVM agents, after rebooting the new system.
To configure SFCFS and CVM agents on the new node
1
Start the VCS server and vxfen on system03.
a
Use hastart on system03 for starting the VCS server.
b
For starting vxfen in the disable mode, run the following commands on
system03:
# echo vxfen_mode=disabled > /etc/vxfenmode
# /sbin/init.d/vxfen start
c
For starting vxfen in the enabled mode:
Copy the following files from one of the existing cluster nodes to
system03:
/etc/vxfenmode
/etc/vxfendg
Run the following command:
2
Check that there are no service groups dependent on CVM, such as SFCFS,
that are still online:
# hagrp -dep cvm
3
If there are any dependencies, take them offline, then take the CVM service
group offline:
# hagrp -offline cvm -sys system01
# hagrp -offline cvm -sys system02
4
Open the VCS configuration for writing:
# haconf —makerw
5
Add the new node to the CVM system list and specify a failover priority of
zero:
# hagrp —modify cvm SystemList -add system03 X
where X is one more than the index of the last system in System list of CVM
service group in /etc/VRTSvcs/conf/config/main.cf.
6
Add the new node to the CVM AutoStartList:
# hagrp —modify cvm AutoStartList system01 system02 system03
7
Node ID can be obtained from
/etc/VRTSvcs/conf/config/main.cf. Add the new node, system03,
and its node ID, #, to the cvm_clust resource:
# hares —modify cvm_clus CVMNodeId -add system03 2
8
Write the new VCS configuration to disk:
# /sbin/init.d/vxfen start
of
CVMNodeId
