WHOA. OK, my bad for not reading the recovery disk details, but geez, at least 
include this information in the field notice. At least something that says, 
“hey - you need to read the recovery release notes for up to date information, 
but be prepared to have to rebuild the server after you recover.”

Geeeez.

Hello all,

Just wanted to throw this one back out there to the group. I’m upgrading our 
lab emergency responder from 12.0 affected to 12.5(1)a. This upgrade failed for 
some reason I’ve yet to determine with TAC, but part of the process during the 
upgrade is to roll back to the previous version and reboot if there is a fault 
during upgrade.

Once this rebooted I got dumped into the condition described in the field 
notice and have to recover.

TAC also advises that if you use the recovery ISO that you rebuild the server 
afterwards. CER for sure has said this before in the documentation, but others 
do as well:

Rebuild Server After You Use the Recovery Disk

Cisco recommends that you rebuild the server, after you use the recovery disk 
to bring a server with a corrupted file system into a bootable and 
semifunctional state. For more information, see

________________________________

You may notice missing directories, lost permissions, or corrupted softlinks, 
if you do not rebuild the server.


I would claim here that this is not a corrupted file system, but in going back 
to re-read the field notice, I wonder if the action it is prescribing is to use 
the recovery ISO to repair the boot image for the appliance before you run into 
trouble and need to work out of it. That’s unclear to me. I did not expect the 
upgrade to fail and put me in this boat – if you are planning to upgrade out of 
the affected versions I suppose have the recovery software handy.

Happy loading.
