Switch Stack version mismatch best way to fix 100s of switches

[scott.knowles]

Hello, I'm looking for best solutions/tools to fix version mismatch on 100s of switch stacks at multiple locations. one or more switches on stacks with mismatch codes. We would like to be proactive and get them fixed before one of the switches gets rebooted for whatever reason and not come back up. The Enterprises network switches are on Solarwinds. We've used scripts in the past for other switch config changes, but wondering is there a better way? In case you're wondering why we have mismatches. We started to move to a new release code and found that the new code had a bug with ISE...., SOOooo we had to back track.

Any suggestions would be appreciated.  TIA

OLD devices you can copy from Master flash to version mismatch device as below :

Example :

OLD :

#copy flash:myimage-file.bin flash4:
#boot system switch 4 flash:/myimage-file.bin
#wr mem
#reload slot 4

sw#archive copy-sw /destination-system 4 1 (from switch 1 to switch)

Cat 9300 and 3850 also work.

Will a v-mismatch switch reboot once auto upgraded in install mode from the 9300 stack in Auto-upgrade enabled?

[balaji.bandi · Accepted solution]

if auto-upgrade is enabled globally (default disabled)  then it upgrades automatically and joins the stack (be patient take 20-25minutes)

but my take, when you see v-mismatch, manually auto-upgrade mismatch switch using same commands.

Later clean up inactive packages from all devices.

Next question - by changing the switch to Install mode from Bundle and enabling auto-upgrade. Will the v-mismatch switch auto-grade? Looking for the least impact to the clinical staff.

[balaji.bandi · Accepted solution]

yes install mode if you put global config auto upgrade it does.
