Instead of using DNS to repoint traffic to the backup host, you can disable the ip on the primary node, then reassign the ip to the backup node. Only delay will the the arp requests in this scenario. Multiple ip's can be assigned to both hosts to ensure the machines stay network accessible:
During normal operation (primary active):
hostA (primary):
trunk0: 10.1.1.100, 10.1.1.101
hostB (backup):
trunk0: 10.1.1.111
During failover operation (backup active):
hostA (primary):
trunk0: 10.1.1.101
hostB (backup):
trunk0: 10.1.1.100, 10.1.1.111
Your DNS would then have an A record for the following:
remedy_primary.company.com -> 10.1.1.101
remedy_backup.company.com -> 10.1.1.111
Your users would simply log in to remedy.company.com, regardless of which node is active.
To access the servers using other tools (ssh, sftp, telnet, etc), you can use the other hostnames (e.g., remedy_primary).
