Hi folks,
i just recently upgraded my IOS version from 16.3.5b to 16.6.8. This is upgrading IOS on install mode
The only thing I’m unsure on is how critical the boot variable is:
Set Boot Variable
Step 4
Use the boot system flash:packages.conf command to set the boot variable.
Switch(config)# boot system flash:packages.conf
Switch(config)# exit
Use the write memory command to save boot settings.
Switch# write memory
Use this command to verify BOOT variable = flash:packages.conf
Switch# show boot system
We’ve rebooted a 2nd time as when I do a ‘show boot’ command it tells me at next boot it will update but a 2nd reboot didn’t.
Switch#sh boot
---------------------------
Switch 1
---------------------------
Current Boot Variables:
BOOT variable does not exist
Boot Variables on next reload:
BOOT variable = flash:packages.conf
Manual Boot = no
Enable Break = no
Boot Mode = DEVICE
iPXE Timeout = 0
The switch was upgraded to 16.6.8 is install mode, just unsure what this component and if it is essential

Hi,
I understand. You are concern about this:
BOOT variable does not exist
And I know you only have one switch and not a stack but every switch has a number. In this case, it is switch 1. So maybe try this:
boot system switch 1 flash:packages.conf
and test again.

Hi,
Try this:
boot system switch all flash:packages.conf
after reboot, you should see this in show boot output:
BOOT variable = flash:packages.conf;

Hi Reza,
As seen on the output shown BOOT variable = flash:packages.conf
What we are concern about is the below still not updating after the second reboot that the BOOT variable does not exist and it is still showing Boot Variables on next reload:
BOOT variable = flash:packages.conf
Current Boot Variables:
BOOT variable does not exist
Boot Variables on next reload:

In addition this is only a single switch we are upgrading not a stack of 3850 switches.
Thanks

That is what I would look out for.
