Dual Core, Dual Sup 720 6500 IOS Upgrade

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.

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
