Script to check one command and if it fails moves to other command

Input is list of Server's, script is basically to remove old_rootvg, So it should check first command "alt_rootvg_op -X old_rootvg" if it passes move to next server and starts check and if it fails moves to other command "exportvg old_rootvg" for only that particular server. I came up with below, but its running both the commands on all the server's, which i dont want to.

Code:
#!/usr/bin/ksh
# set -x
ofile=/old_rootvg_cleanup_logs/old_rootvg-cleanup.$$
for server in `cat host_list.txt`
do
remove_old_rootvg=`ssh $server alt_rootvg_op -X old_rootvg`
if [ $? != 0 ]
then
echo "Command Failed at $server"
else 
export_old_rootvg=`ssh $server exportvg old_rootvg"
fi
echo " $server   |   $remove_old_rootvg  |    $export_old_rootvg" >> $ofile
done

bup-on(1)						      General Commands Manual							 bup-on(1)

NAME
bup-on - run a bup server locally and client remotely SYNOPSIS
bup on <hostname> index ... bup on <hostname> save ... bup on <hostname> split ... DESCRIPTION
bup on runs the given bup command on the given host using ssh. It runs a bup server on the local machine, so that commands like bup save on the remote machine can back up to the local machine. (You don't need to provide a --remote option to bup save in order for this to work.) See bup-index(1), bup-save(1), and so on for details of how each subcommand works. This 'reverse mode' operation is useful when the machine being backed up isn't supposed to be able to ssh into the backup server. For example, your backup server can be hidden behind a one-way firewall on a private or dynamic IP address; using an ssh key, it can be autho- rized to ssh into each of your important machines. After connecting to each destination machine, it initiates a backup, receiving the resulting data and storing in its local repository. For example, if you run several virtual private Linux machines on a remote hosting provider, you could back them up to a local (much less expensive) computer in your basement. EXAMPLES
# First index the files on the remote server $ bup on myserver index -vux /etc bup server: reading from stdin. Indexing: 2465, done. bup: merging indexes (186668/186668), done. bup server: done # Now save the files from the remote server to the # local $BUP_DIR $ bup on myserver save -n myserver-backup /etc bup server: reading from stdin. bup server: command: 'list-indexes' PackIdxList: using 7 indexes. Saving: 100.00% (241/241k, 648/648 files), done. bup server: received 55 objects. Indexing objects: 100% (55/55), done. bup server: command: 'quit' bup server: done # Now we can look at the resulting repo on the local # machine $ bup ftp 'cat /myserver-backup/latest/etc/passwd' root:x:0:0:root:/root:/bin/bash daemon:x:1:1:daemon:/usr/sbin:/bin/sh bin:x:2:2:bin:/bin:/bin/sh sys:x:3:3:sys:/dev:/bin/sh sync:x:4:65534:sync:/bin:/bin/sync ...
