Cisco 6509-E VSS Replace Supervisor

[leonardo_liberati]

Good Morning,

we have to replace the sup720 of a vss bundle.

I've read the how-to on cisco.com web site:

http://www.cisco.com/en/US/products/ps9336/products_configuration_example09186a0080a64891.shtml

but I have some questions about the replacement:

When we perform the recovery procedure is likely to malfunction despite one of the two nodes VSS is currently up and running?

What kind of impact we can have?

May occur during recovery procedure a fault on the running machine?

In the event of a fault which these cases the recovery process and especially the estimated timing?

Note: We have a VSS with FWSM (one for each 6509) and with WISM (two for each 6509).

Thanks a lot

Leonardo

Jon we have these two images:

s72033-adventerprisek9_wan-mz.122-33.SXI4.bin

s72033-adventerprisek9_wan-mz.122-33.SXI3.bin

There was a blackout in our enviroment...but this VSS never gave us problems!!! I suppose for a faulty supervisor but...at this point...i don't know...    

Anyone can help me?

But which one of those images is the active supervisor running, ie. you copied SX14 but is your active supervisor running SX13 ?

If you are sure the image is compatible then have a look at this link -

it may help.

I have already red that page...but I've not gave that error... I don't know if is correct to deploy that synch in this case.

Both Supervisor cards need to run the same IOS version and same feature set.
