Dear Team,
There are two servers pwd01.us.com and pwd02.us.com.
d01 is the prod server and d02 is the Disaster recovery(DR) backup server.
Both are Red Hat Enterprise Linux 7.0 on Virtual boxes.
My manager wants to do a DR test on d01.
I put the following steps and it was rejected

Unix SA to do failover of  zone (pwwmap01) from the Prod node (pwd01.us.com) to the DR node (pwd02.us.com)..
hagrp –switch pwd01.us.com –to pwd02.us.com
tail /var/VRTSvcs/log/ engine_A.log to check for errors and/or successful completion, Check with:
hagrp -state d01
zlogin d01 check all SMF services have started correctly
svcs –xv

Open in new window


To which the Unix SA's commented:
Give better, more meaningful instructions other than "DO a DR test on the Pre-prod server : d01.us.com and d02.us.com If you mean a failover, then show which zone is to be failed over.  The DR Plan relates to Solaris zones, whereas the server you mention (d01) is a Linux machine. So completely different operating systems. In fact, VCS isn't even running on that machine.

I am not sure what unix commands are needed to do a DR test and what applications should be used for the same.
Please help

The test is n switching from prod to dr all applications should continue to operate.

Best way, you first have to have a full understanding of which applications, dependencies exist for prod server, then on transition, you will check to make sure those applications continue to function.

Redhat has their own, cluadmin I think.....
Presumably you have access to both systems.

DDNS server can also be an option.
