Sintomi

On attempt to run "install all" command, the switch returns the message "Pre-upgrade check failed. "Return code -1."

No indications of what is wrong, md5sum of the firmware files are good. Enough space on the bootflash: and also on the standby supervisor but still the "install all" command fails with "Return code -1."

Causa

The command 
"show incompatibility-all system bootflash:m9700-sf2ek9-xxxx.bin"

 runs fine.

The command 
 "show install all impact kickstart bootflash:m9700-sf2ek9-kickstart-mz.xxxx.bin system bootflash:m9700-sf2ek9-mz.xxxx.bin" fails with "Return code -1."

(This is the same message as the "install all" command.)

Risoluzione

Workaround:
  1. Perform a "system switchover" command to failover to the second supervisor. Wait until the command completes. Use the command "show system redundancy status" to confirm the action completes.
  2. Perform a second "system switchover" command to go back to the previously active supervisor where the upgrade code currently resides. 
  3. Rerun the "install all" command and upgrade should complete.
