Cold standby master server
We are performing Netbackup upgrade including hardware refresh for a customer. The current version is 220.127.116.11 and will be upgraded to 18.104.22.168. The server hardware would also be refreshed.
The question I have is, they are aiming to achieve a cold standby server as an immediate replacement of active master server. The cold standby server will be installed and configured with exactly similar configuration(hostname; IP; hardware; NBU version) and will always remain shutdown unless required to power on. The catalog will be stored on a storage LUN and will be mounted on active master server. In event of active master server crash/disaster we can mount the same LUN on cold standby server and start the services. Required necessary actions will be taken so that the arp cache will be updated to point to new server(as the MAC will be different even if IP is same).
Please let me know if this is a workable option.
