upgrading 6509 in VSS mode

Hi guys,

we have two 6509 running in VSS mode and we encountered the bug described here

https://tools.cisco.com/Support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId=CSCtc41114

so basically we can't ssh into the chassis.

So we're planing on upgrading the chassis to fix it, which I couldn't practice in lab...

The current image is "sup-bootdisk:s72033-ipservicesk9_wan-mz.122-33.SXI3.bin" and we wou'd like to upgrade to s72033-ipservicesk9_wan-mz.122-33.SXI8.

I read the guidelines for upgrading here http://www.cisco.com/en/US/docs/switches/lan/catalyst6500/ios/12.2SX/configuration/guide/vss.html#wp1172503

but I noticed something I'm not familiar with :

eFSU Upgrade on an Installed Modular Image Example

This example shows how to perform an an eFSU upgrade on an installed modular image:

Router# copy ftp://172.18.108.26/s72033-advipservicesk9_wan-vz.122-33.SXI2 sup-bootdisk:s72033-advipservicesk9_wan-vz.122-33.SXI2.bin

Router# copy ftp://172.18.108.26/s72033-advipservicesk9_wan-vz.122-33.SXI2 slavesup-bootdisk:s72033-advipservicesk9_wan-vz.122-33.SXI2.bin

Router# install file sup-bootdisk:s72033-advipservicesk9_wan-vz.122-33.SXI2.bin sup-bootdisk:/newsys

Router# install file slavesup-bootdisk:s72033-advipservicesk9_wan-vz.122-33.SXI2.bin slavesup-bootdisk:/newsys

The thing is, the install command is not available on my switch :

ecore#ins?

% Unrecognized command

So I guess I'm not running a modular IOS.

I read a bunch of things about monolithic and modular IOS but I'm kinda lost here...

Could you tell me how can I tell the difference between a modular and a monolithic image?

And in my case, what should I do after copying the image on the sup-bootdisks?

Is there any other impact on the upgrade process?

Thank you for your answers!!
