A 6500 has been upgraded from CatOS to IOS. And image was installed on bootflash (not in slot0). All upgrade procedures were followed and image was re-installed on sup-bootflash.
Here is the BOOT variable after upgrade:
Router#remote command switch show bootvar
BOOT variable = bootflash:c6sup22-jsv-mz.121-26.E8.bin,1
CONFIG_FILE variable =
BOOTLDR variable = bootflash:c6msfc2-boot-mz.121-11b.E4.bin
Configuration register is 0x0 (will be 0x2102 at next reload)
Should "BOOT varialbe = sup-bootflash:c6sup22-xxx.xxx" format instead of "BOOT variable = bootflash:c3sup22-xxx.xxx".
Dir show no c6sup22-xxx.xxx on bootflash but has c6msfc2-xxx.xxx and other.
PS. switch was rebooted a couple times and everything looks fine.
