[c-nsp] Software versioning on SUP720s

[Geoffrey Pendery]

If your goal is to intentionally run different code on your two
supervisors, with a cold standby to take over in case some bug in SXH5
causes a supervisor crash, then no it's not a problem you've got it
operating as planned.

But few people do it that way, I assume you want the whole system to
be running SXH5, and have a Hot standby who will take over quickly in
the event of hardware failure.  If that's the case, then like Matthew
said, you need to get the SXH5 code on your standby sup, and reboot it
on that code ("redundancy reload peer" IIRC).  They should show up
with the same IOS in the "show module" command, and should be Standby
Hot, not Standby Cold.

You mention booting off a CF card.  If that's your desired method, you
need a second CF card plugged into the second supervisor, with the
same code on it.  Otherwise you can boot from the sup-bootdisk, but
you still need a copy on both supervisors.  Any filesystem (disk0,
bootflash, sup-bootdisk, etc) can be reached on the backup Supervisor
by calling it slave[name of filesystem], like slavedisk0: or
slavebootflash:
