Question: Can I boot my new IOS by simply putting the system into the flash card and issueing command router(config)# boot system disk0:filename?
Do I need a bootloader?
Do I need an msfc boot image?
How do I easily zero out the current boot variable so that I don't get a string of boot variables when I do a show boot?
When I do a copy run star, on the machine, will the disk0:filename value be copied over to the redundant sup?
SITSF-Central-Cat#sh boot
BOOT variable = sup-bootflash:,1;sup-bootflash:c6sup22-psv-mz.121-19.E1.bin,1;sup-booten,1;disk0:c6sup22-psv-mz.121-26.E8.bin,12
CONFIG_FILE variable =
BOOTLDR variable = bootflash:c6msfc2-boot-mz.121-13.E3.bin
Configuration register is 0x2102
Standby is up
Standby has 227328K/34816K bytes of memory.
Standby BOOT variable = bootflash:,1;bootflash:c6sup22-psv-mz.121-19.E1.bin,1;booten,1;disk0:c6sup22-psv-mz.121-26.E8.bin,12
Standby CONFIG_FILE variable =
Standby BOOTLDR variable = bootflash:c6msfc2-boot-mz.121-13.E3.bin
Standby Configuration register is 0x2102
Solved! Go to Solution.

startup-config should cover it. Make sure to issue a 'wr mem' so the running-config will be transferred to the startup-config.
Good luck tonight and please post results.

"Can I boot my new IOS by simply putting the system into the flash card and issueing command router(config)# boot system disk0:filename?"
Yes.
"Do I need a bootloader?"
No.
"Do I need an msfc boot image?"
No.
"How do I easily zero out the current boot variable so that I don't get a string of boot variables when I do a show boot? "
You need to remove all the boot system flash ... from the running-config. Keep only the one from the current IOS.
"When I do a copy run star, on the machine, will the disk0:filename value be copied over to the redundant sup?"
Let'see the output from typing 'show redundancy'.

Thanks for the help.
I still don't understand how to delete the BOOT variable, prior to loading the new pointer to the new IOS image. i.e. geting rid of the old "boot system" value.
Here is the show redundancy:

Slot 2 : Standby

You are running a very old IOS version there.
Please follow this link:
http://www.cisco.com/univercd/cc/td/doc/product/lan/cat6000/12_1e/swconfig/redund.htm
and configure auto-sync startup-config.
Are you running hybrid (CatOS/IOS) or native IOS ?

I got the redundancy right = rpr+ (best you can do with Sup 2 blades). I didn't set the autosync though - didn't notice that part, but it looks like it has a default setting anyway. I did a show run and found the following already set:
redundancy
mode rpr-plus
main-cpu
auto-sync running-config
auto-sync standard
See command:
Router(config-r-mc)# auto-sync {startup-config | config-register | bootvar | standard}
standard
Automatic synchronization of the startup-config, BOOTVAR, and config-registers.
(Standard mode apparently covers all parameters except running-config????.)
I am native (part Cherokee and Chakta), I believe. That is where I want to be, i.e. I am not running CatOS on the supervisor and IOS on the MSFC. It is all just one big happy IOS with rpr+, and autosync stuff (thanks for that).
I am doing the upgrade tonight and will post the results.

Upgrade went well.
I needed to remove some items in the boot string:
router(config)# no boot system bootflash:
router(config)# no boot system sup-bootflash:
There was also a 5 minute outage when the forced failover was done. This couldn't be avoided because the supervisors were running two different IOS versions and couldn't do hot standby.
Good commands:
router# sh red
router# sh red stat
router# sh ver
router# hw-module module module# reset (this command boots the new IOS)
router# redundancy force-switchover (this command makes the standby sup, with the new IOS running, the active sup.)
When you do the force-switchover, you go down for 5 minutes and then come back up with the new version running.
Thanks for all the help.

Some other good commands:
router# Show log
router# term mon
router# show boot
It may have saved failover time if I had full diagnostics turned off.
