On LDAP1 Started the cman and rgmanager services <br />

<br />
Checked in /var/log/messages for any error . cman and rgmanager Services started successfully .<br />
<br />
Checked the cluster status <br />

ldap2.pbifmsiwdms.pjb 2 Online<br />
<br />
'''But Services were still not showing.'''<br />
<br />
We have to enable the service manually <br />
<br />
#clusvcadm -e dummy_httpd -m ldap1.pbifmsiwdms.pjb <br />
( where dummy_httpd is the service named defined in /etc/cluster/cluster.conf )<br />
'''But Service dummy_httpd failled''' . <br />
<br />
Checked the log and found '''/etc/init.d/httpd''' , could not start . <br />
<br />
Tried to start httpd service via '''"/etc/init.d/httpd start"''' , but failed .<br />
<br />
Checked the log i.e /var/log/httpd/error_log and found <br />
[Sat May 21 10:14:45 2016] [error] Unable to verify certificate 'Server-Cert'. Add '''"NSSEnforceValidCerts off"''' to nss.conf so the server can start until the problem can be resolved.<br />
<br />
We added '''NSSEnforceValidCerts''' off in /etc/httpd/conf.d/nss.conf in virtualHost context .<br />
<br />
Checked the httpd service via starting it on the cli , it worked successfully . <br />
<br />
Then we stopped this service as it is controlled by cluster process. <br />
<br />
We enabled the service manually again <br />
#clusvcadm -e dummy_httpd -m ldap1.pbifmsiwdms.pjb <br />
'''The services started successfully''' .<br />
