I need some advice on disaster recovery for a Cisco MCS 7828, Call Manager 6.0.1, Unity Connection 2.1 system.
This system was installed about 5 years ago by a reseller. In a recent disaster planning audit, we discovered that the hardware is at End of Life and we do not have the original installation disks for the software. We are taking a backup of the system on a regular basis using the Cisco disaster recovery tools.
The problem is what happens if we experience one of more disks crashing and they have to be replaced?
We currently have no OS installation disks or Call Manager / Unity Connection installation disks to get the system back up to a point where we could restore the database and other information from our backup.
I would like to get some additional years out of this system (assuming the motherboard stays operational) but could use some advice on how to deal with the need for a complete "cold metal" restore of the OS software.
