ASR 1001-HX Upgrade Procedure 1 RP

[joeldoetsch]

Hello,
I have a couple of ASR 1001-HX devices, each with only 1 RP.  I've been trying find documentation on how to perform an upgrade (going from 16.9.5 to 17.3.4), but all the documentation seems to point to ISSU, which as far as I can tell is not possible without 2 RPs.

Is there a documented procedure similar to those of the past, where I simply pull the new image to the device, change the bootflash variable, and reload?  I so far have been unable to find a non-issu upgrade procedure in Cisco's documentation.

Thanks in advance,
Joel Doetsch

Hi Marce,

That's the same document I've been finding for upgrades, but unfortunately it does not seem to apply to my situation.  From documentation: "Consolidated packages can only be upgraded using ISSU in dual Route Processor configurations. ISSU is not supported for consolidated package upgrades in single Route Processor configurations."

We are running with a singer Route Processor configuration.  Unless I'm missing something, that means we can't use ISSU.  Looking for the method for upgrade that doesn't involve ISSU. 

Thanks,
Joel Doetsch

Have a read of this document:  Cisco ISR & ASR 1k Routers: IOS-XE/Firmware Upgrade (Install Mode)

Hope this helps.

This is an incredibly useful document, and I'll be bookmarking it.

Thanks so much for writing that up!

Cheers,
