IOS XR Release 5.3.4 for ASR9000 and CRS

IOS XR Release 5.3.4 Introduction

IOS XR release 5.3.4 is a supplemental Extended Maintenance Release for the ASR9000 and CRS platforms. The previous EMR 5.3.3 maintains the EMR status. IOS XR release 5.3.4 is the Cisco suggested software release for all ASR9000 and CRS deployments.

The driver for XR release 5.3.4 was to provide a leaner 5.3.x SW package for the older generation of ASR9000 and CRS cards because beyond XR release 5.3.x these older generation cards are not supported. The end goal is much more than that: XR release 5.3.4 enhances the quality of 5.3.3 release by:

• Hardening target areas:
• A9K-VSM-500 infrastructure
• BNG:
• special attention to PWHE and Satellite as subscriber access interfaces
• Geo-Redundancy
• FPD
• EnvMon on ASR9K
• Infrastructure hardening on CRS
• Integrating selected SW fixes:
• Released 5.3.x Production SMUs
• Selected customer found SW defects (bug scrub, early trial, 5.3.x deployments)
• fixes for SW bugs found during 5.3.4 test cycle

XR Release 5.3.4 Content and Delivery

Feature content of XR release 5.3.4 is identical to 5.3.3.

Hi

Kindly assist here

I am trying to upgrade from 5.1.3 .to 5.3.4 and i get the below error

The intsall operation failed due to a system error,

Node failed to respond when completing disk checks

See attached

First verify whether the pies were correctly copied by verifying the md5 sum. If that checks out fine, try restarting the instdir  and insthelper processes and repeat the install.

hope this helps,

Hi Alek

Thanks for your prompt response

Kindly advice with the commands i should run step by step so i can troubleshoot properly

[Aleksandar Vidakovic]

If you have copied over the pies to the harddisk on the router, use "show md5 file <file>" to check the md5 sum. Compare that to what you see on CCO (https://software.cisco.com/download/navigator.html).

To restart the instdir and insthelper processes on the active RP, run:

process restart instdir location 0/RSP<n>/CPU0

process restart insthelper location 0/RSP<n>/CPU0

If this doesn't help, please collect "admin show tech-support install" and open a TAC SR.

Hi, Aleksandar:

I've been looking for a couple of days for the upgrade procedure document for a CRS (from 4.3 to 5.3.4). You guys usually post it here:

https://www.cisco.com/web/Cisco_IOS_XR_Software/index.html

It's not there (and the 5.3.3 link is broken). Any chance you can provide the 5.3.4 doc for a CRS upgrade?

Thanks!
