Hi Sittichai,

Could you explain in more details on why do you want to change redunancy mode to none? Do you use IOS process redundancy on it?

Also, please post "show platform" command output here.

Generally, if you do not care about service impact due to the router reload, on any ASR router you can change the boot string to point to new image, save configuration and reload the router.

For less service impact, you should use ISSU procedure, which you can see in the following guide:

current I used ASR1002 1 unit version Version 12.2(33)XNF2   IOS-XE :asr1000rp1-advipservicesk9.02.06.01.122-33.XNF1.bin

and redundancy mode sso

but, I need to single process , I can be upgrade  asr1000rp1-advipservicesk9.03.04.03.S.151-3.S3.bin in ASR1002 ?

and I refer by command issu runningversion and result

ASR#issu runversion
--- Starting local lock acquisition on R0 ---
Finished local lock acquisition on R0

FAILED: Operation runversion cannot be performed: no install in progress

I just need redundancy mode none  and upgrade IOS-XE from 12.33 to 15.1-3 

PS. now :bootflash:/IOS-XE/packages.conf   ,

I will change bootflash:/IOS-XE/asr1000rp1-advipservicesk9.03.04.03.S.151-3.S3.bin and change redundancy mode none and reload for take router  ---- but I don't sure after tranfrom 12.33 to 15.1

please make sure to me.

Thank you,

Hi,

If you want to change to single process, config the following:

     Router# configure terminal

     Router(config)# redundancy

     Router(config-red)# mode none

     Router(config-red)# end

     Router#

There is no need to run "issu runversion". Since you are doing service impacting upgrade with router reload, you just need to change the boot string and reload:

     Router#show run | i boot     //find the current boot string, e.g. "boot system bootflash:/IOS-XE/packages.conf"

     Router# configure terminal

     //remove the old boot string now, using the output you got above, e.g.:

     Router(config)# no boot system bootflash:/IOS-XE/packages.conf

     //add new boot string, specify correct path

     Router(config)# boot system bootflash:/IOS-XE/asr1000rp1-advipservicesk9.03.04.03.S.151-3.S3.bin

     //save config

     wr

     //reload to load new image

     reload

Note that this is service impacting upgrade!

You can also use ISSU packages upgrade procedure but that requires 2 IOS processes to be configured:
