[f-nsp] Hitless upgrade on MLXe

[Youssef Bengelloun-Zahr]

Hello community,

A quick follow-up on this one.

We upgraded yesterday from 540a to 540b and decided to try the hitless
procedure.

We were not able to use it for some kind of reason, here are the message we
hit :

(With new OS in primary and secondary flash)

er01-par01#hitless-reload mp primary lp primary
Are you sure? (enter 'y' or 'n'): y
Running and Flash Images Mismatch.
Hitless OS Upgrade Aborted.
Please refer to Release Notes for Hitless OS Image Version compatibility.

er01-par01#hitless-reload mp secondary lp secondary
Are you sure? (enter 'y' or 'n'): y
Active MP and LP (slot 1) Flash Images Mismatch.
Hitless OS Upgrade Aborted.


(With new OS only on the secondary) :

er01-par02#hitless-reload mp secondary lp secondary
Are you sure? (enter 'y' or 'n'): y
Running and Flash Images Mismatch.
Hitless OS Upgrade Aborted.
Please refer to Release Notes for Hitless OS Image Version compatibility.

We carefully respected the procedure. Provider is going to look into it.

BTW, simplified upgrade procedure is a blessing ;-)

My 2 cents.

Y.
