ISSU upgrade from R2207 to R2308P01

[Jyce]

Hi Gurus,

I tried to upgrade 5920AF Switches using ISSU command but it fails completely. Here is the procedure I applied:

 - Copy R2207H01 Patch on slot1 & slot2.

 - Install the Patch on both switches (using install activate patch & commit)

 - Check patch is correctly installed (using display install active)

 - Check ISSU state (display issu state)

 - Check compatibiliy matrix (issu comp-matrix file ...)

 - Upgrade slave switch using ISSU command (issu load file ...)

After this step, slave switch never join back the IRF stack.

Should I upgrade through an intermediate firmware to have no service interuption ?

Thanks

We did this a while back.  On a 2 chassis system the command set we used was:

issu load file ipe flash:/5900_5920-CMW710-R2208P01.ipe slot 2
display boot-loader
issu run switchover slot 2
issu accept
issu commit slot 1

Hi,

From I can see, it looks like upgrade to R22xx release is compatible while, trying to upgrade to R23xx release isn't and require service interruption.

Thanks for your input.

Hi Jyce

Yes, that's true. Unfortunately ISSU Compatible from 2207 to 2308 is not supported. See the release notes.
