I am trying to do an ISSU on Cisco 4k switch.
1) I booted both of the supervisor of the switch with the same image.
2) I also used the
boot system bootflash command with both of the image names, setting the boot variable. So when I do
sh bootvar from privilege mode I am getting both of the images name in the bootvar variable and the value of the conf-reg as 2922
3) I have loaded both of the image the one which switch is running and the one to which i want to upgrade in the bootflash of the switch and also in the slave bootflash which may not be necessary.
4) I have also set one rommon mode variable
5) When i do
show redundancy the switch is in the SSO mode.
6) When i do
sh bootvar it contains only two images the one which is running and the one to which i want to upgrade.
7) I have also set the switch to be in auto-boot mode one of the pre-requisite of ISSU, From the
configure terminal mode I have used the command
conf-reg 0x2102 but it is taking the value as 2922 by itself which I am unable to figure out, but i guess that must be fine cause the last value is 2.
But when I run the
issu loadversioncommand I get this message
%Active boot variable is Invalid.
How can I resolve this problem?
