Doing a bug scrub on our dual core, dual Sup 720 6500s tonight. We are going from s72033-advipservicesk9_wan-mz.122-33.SXI4a.bin to SXI9. I want to get a second set of eyes on my script since I have not done this for about 1 1/2 years. Following this doc: http://www.cisco.com/en/US/products/hw/switches/ps708/products_configuration_example09186a0080a98f3c.shtml.
Please comment.
Thanx

Script:
Backup
sh ver
remote command switch show version
TFTP image to disk0: (907853824 bytes available, plenty of room)
sh boot
Change boot variable:
no boot system disk0:s72033-advipservicesk9_wan-mz.122-33.SXI4a.bin
boot system disk0:s72033-advipservicesk9_wan-mz.122-33.SXI9.bin
Reload standby
hw-module module 8 reset
redundancy force-switchover
Repeat

This will work fine. Remember when you are ISSU to upgrade, it takes longer because you have to reboot multiple time
1-reboot the stand-by
2-reboot the primary
3-if you want to have the old primary as your primary again, you have to reboot the stand-by one more time.
Or if you have an outage window, you can simply load the new IOS in both Sups, reboot the entire switch.
Primary and stnad-by will be the same slots as before
That is all

I'd use "sh redundancy" instead.
no boot system disk0:s72033-advipservicesk9_wan-mz.122-33.SXI4a.bin
boot system disk0:s72033-advipservicesk9_wan-mz.122-33.SXI9.bin
I am not in your shoes right now but I won't do this. I would let SXI9 be my primary boot string and a "just in case" with SXI4a as a secondary boot string in case SXI9 fails to boot.
boot system disk0:s72033-advipservicesk9_wan-mz.122-33.SXI9.bin
boot system disk0:s72033-advipservicesk9_wan-mz.122-33.SXI4a.bin

Not a bad idea, I can always take the secondary string out of config later.

Exactly!

So my modified script is:
Backup
sh ver
remote command switch show version
sh redundancy
remote command switch sh redundancy
TFTP image to disk0: (907853824 bytes available, plenty of room)
sh boot
Change boot variable:
no boot system disk0:s72033-advipservicesk9_wan-mz.122-33.SXI4a.bin
boot system disk0:s72033-advipservicesk9_wan-mz.122-33.SXI9.bin
boot system disk0:s72033-advipservicesk9_wan-mz.122-33.SXI4a.bin
Reload standby
hw-module module 8 reset
remote command switch show version
redundancy force-switchover
Repeat for module 7

Should be fine.
