We have 2 x MDS 9124 switches at the core of our SAN and as part of our DR testing I have to replace one of the switches with a new unit i.e. restore the swtich config from a backup to a new unit.
We use Kiwi CatTools to backup the config (basically copy run tftp).
Are the basic steps:
1. Upgrade/downgrade replacement switch to same OS as running on failed switch
2. Connect all cables as per failed unit
3. Add basic network commands to get on LAN
4. copy tftp start to get backup config onto new switch
5. Add any licence keys
6. Reload and check
Are there any unique values in the backup config that must be replaced (e.g. WWN's) before doing the restore?
Is there a Cisco DR document that covers this issue?
