[cisco-voip] recovery disk - what's it worth?

[Lelio Fulgenzi]

Super! Thanks everyone!

It didn’t help that the PUT process reversed the PLM upgrade and recovery images for v11.5(1)SU2 on me today! I was very confused that the PLM recovery image from PUT was the exact same name and checksum as the upgrade file from CCO.

When I went to get the upgrade image from PUT for PLM, it was the recovery image. Yeesh.

I guess we should think about downloading and storing the recovery images for each of the applications.

The recovery.iso is only good for a variety of boot/disk block and partition issues. It won’t help you if your DR was like .... “UCS server xyz lost 2 disks in a RAID5”. That is an new VM build and a drs restore ... etc (not that other methods don’t exist *nods at Mr. Snapshot and Mr. clone*, but it is the only “fully supported” way).

Recovery disks are used when your CUCM won't boot or you can't login.  There is a file repair utility, as well as a password reset utility, plus something else I don't remember.  It has 4 options on the menu.  In the lab, I've also used it to get into the system as root and mount the partitions, used it to delete logs that were filling up from that nasty vmtools bug we had about a year ago.

You can probably mount that ISO into an empty VM and boot it to see it.

Our disaster recovery plan has always been boot with disk/ios image and restore from latest backup. We’ve tested this on a few occasions and it works well. Well, as good as documentation can be expected.

We typically try to do this as quickly as possible after an upgrade to ensure the bootables we have work and we have the appropriate inline upgrade ISO images. We get the bootables through PUT when required and the upgrades through CCO software downloads. We usually also try to get the bootables published by the TAC for us. For example, PUT only has v11.5(1)SU3b bootables, not SU4.

The question is… what scenarios are the recovery disks used for? Have people used those? Have they worked?

For some reason, I’m flashbacking to wordperfect recovery software that never recovered a single file. 😉
