IOS upgrade

I have been reading up on upgrading our 6509 from 12.1(13)E8 t0 12.1(20)E2.

When I do a "dir bootflash:" I get this.

Directory of bootflash:/

1 -rw- 1693168 May 22 2003 00:29:45 c6msfc2-boot-mz.121-8a.EX

2 -rw- 13087784 May 22 2003 00:29:58 c6msfc2-psv-mz.121-13.E6.bin

31981568 bytes total (17200360 bytes free)

When I do a "dir sub-bootflash:" I get this.

Directory of sup-bootflash:/

1 -rw- 23689456 Oct 08 2003 19:13:13 c6sup22-dsv-mz.121-13.E8

31981568 bytes total (8291984 bytes free)

My running config shows this for the boot system.

hostname Cisco6509

!

boot system sup-bootflash:c6sup22-dsv-mz.121-13.E8

And my "sh bootvar" show this

Cisco6509#sh bootvar

BOOT variable = sup-bootflash:c6sup22-dsv-mz.121-13.E8,12

CONFIG_FILE variable =

BOOTLDR variable =

Configuration register is 0x2102

The way I understand all this is that

bootflash is the MSFC internal SIM

sup-bootflash is the Supervisor internal SIM

bootsystem in my configuration is set to use c6sup22-dsv-mz.121-13.E8 loaded on the supervisor internal SIM

Configuration register 0x2102 causes the 6509 to use the load specified by the bootsystem in config

If all of this is correct I believe I should format the bootflash to remove the c6msfc2-psv-mz.121-13.E6.bin and c6msfc2-boot-mz.121-8a.EX.

Then copy the new IOS 12.1(13)E8 t0 12.1(20)E2 to bootflash and change the boot system in configuration to bootflash: c6sup22-dsv-mz.121-20.E2

Thanks, Ken

Re: IOS upgrade

The IOS code can not be booted from the MSFC bootflash. It must be booted from either the sup-bootflash or a PCMCIA slot.

The reason for this is because the MSFC is not powered initially during the boot process. The supervisor rommon is in control of the boot process and can only load the images from flash devices that is has direct control of (sup-bootflash: or slot0:)

In order to upgrade, you will need to copy the new file to sup-bootflash: and change you boot system command in the configuration to boot from sup-bootflash: and not from bootflash.

Please check the note on the following link.
