Firmware update in irf stack

[Sandeepani]

HI

I have an issue with updating firmware of the irf stack. I wanted to know how to updatee the firmware of the stack with out getting whole stack down.  When configuring the stack we doesent config one by one as that have there any method to upgrade the whole stack with out rebooting all the switches in the stack?

Thank you

You didn't provide much valuable information about your IRF Stack (HPE SKUs of involved switches, sanitized running configuration, software version currently running, software version you want the IRF stack be upgraded to...and so on)...so, generally speaking (but you need to have some sort of familiarity with IRF management/CLI console), you can verify if your IRF Stack supports ISSU feature or not: ISSU is a method of updating your IRF software stack in a sequenced mode so your stack is never down entirely.
