How to manully configure a node to add existing cluster on Solaris 10 and SFHA5.1

Problem

When you rebuild a node, you might need to manually configure VCS.

Solution

1. Copy below files from running cluster node.  All files should be identical except llttab.

Under /etc
llthosts
llttab  <----------- Change node name, and check nic device.
gabtab
vxfenmode
vxfendg
vcsmmtab <----- this is only for SFRAC
 

 

2. If VCS services are under Solaris 10 SMF control, then you need to enable all below services.

Modify below files, and change START_XXX=1 and STOP_XXX=1.  XXX is below VCS services, such as gab.

/etc/default/
llt
gab
vxfen
vcs

Then, enable services:

# svcadm enable XXX

 

For SFRAC, you need to start service for odm and vcsmm:

# svcadm enable vxodm

# svcadm enable vcsmm

 

Please make sure all services are enabled:

# svcs -a|grep XXX

 

 

3. For 5.1, you need to have cluster uuid, and you can copy from existing cluster node.

# /opt/VRTSvcs/bin/uuidconfig.pl -clus -copy -from_sys<existing node>  -to_sys <new node>

 

 

4. Finally, start cluster on new node

# hastart
