Clarification needed on upgrading IOS image on stack switches (3750)

Hello,

I am upgrading new IOS image on a stack switches of 9 (3750G-48TS) for enabling faeture of SSH as it is currently lacking SSH login feature. I came across through cisco documentation that I can upgrade the new IOS image on all 9 switchs of a stack with a single command. Below is the link for your reference:

http://www.cisco.com/en/US/products/hw/switches/ps5023/products_configuration_example09186a00804799d7.shtml#cfbin1

Right now all switches have the new IOS k9 image copied. Attached file you will find the switch details with current and new IOS image for your reference:

I have a doubt like, if i proceed with the above cisco documentation on step 4 as "boot system switch all flash:/
c3750-advipservicesk9-mz.122-52-SE.bin

Switch(config)#exit
Switch#write memory

will it boot with the new IOS image on all member switches or on only master switch will reboot with the new IOS.

Kindly share the expereinces with a similar situation realted to the stack 3750G-48TS switches.

Much appreciating your response

Regards,

Mohammed

If you reload the master then whole stack will reload and boot up with the new image. You can also try reloading one member switch at a time by using  'reload slot stack-member-number'

Thanks for your reply.

I'll try this as well for an alternative.

cisco documentation that I can upgrade the new IOS image on all 9 switchs of a stack with a single command

Sure you can.  But it's a heart-stopping experience when the switch of this huge stack because it will "pause".  The command is "arch download-sw /dest 1 /dest 2 /dest 3" ...

I have a doubt like, if i proceed with the above cisco documentation on step 4 as "boot system switch all flash:/
c3750-advipservicesk9-mz.122-52-SE.bin

I never use this command unless I have more than one IOS in a switch.  The 3750G-12S, for example, does not have enough flash space for two full IOS.

How many IOS do you have in your switch?  If you have only one, then disregard this.

We have two IOS image on the switches as depicted below:

Re: Clarification needed on upgrading IOS image on stack switche

Re: Clarification needed on upgrading IOS image on stack switche

Do you still need 12.2(25)SEE3?  If not, delete the file and subdirectory using the command "delete /f /r flash1:c3750-ipbase-mz.122-25.SEE3" and so on.

Looks like you need someone to eyeball the switch.

Re: Clarification needed on upgrading IOS image on stack switche

... OR maybe it may just take a little while because you are upgrading from 12.2(25) to 12.2(52) which requires the new IOS to upgrade the Bootstrap and require to boot TWICE.

Re: Clarification needed on upgrading IOS image on stack switche

might be i have to check. As of now i have rollback on the old ios image and the switches are running normal. I need to figure it out tommorow morning.

One way in my mind is that I can break the stack and give the boot variable on individual 9 switches. But I think there is also a way that we can upgrade

IOS and can have the boot variable on the stack switches without breaking stack.

Any help would be appreciated in this regard.

regards,

Mohammed
