[c-nsp] Upgrading VSS switches, modular-monolithic ios??

[Simon Morand]

Hi list,
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
Basically we can't ssh into the switches so we're planning on upgrading the switches to fix it.

The current image is "sup-bootdisk:s72033-ipservicesk9_wan-mz.122-33.SXI3.bin" and we would 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!!
