3850 Switch Stack won't auto upgrade newly added switch

We had 2 3850-48P-S Switches in a stack running version 03.06.06E IOS.  I added a 3rd switch running 03.06.05E and after enabling auto upgrade with the "software auto-upgrade enable" command I rebooted the 3rd switch expecting it to upgrade to 03.06.06E but it reboots back into 03.06.05E.  It is not showing any errors in the stack but I know it is best to keep the stack software at the same version.  I would rather not reboot the whole stack either but need to know why the 3rd switch doesn't auto upgrade or what the easiest way to upgrade it to match software would be without disrupting the first 2 switches in the stack.  What do you think?

Re: 3850 Switch Stack won't auto upgrade newly added switch

Hmmm ... 3.6.6, eh? How's the CPU like?
Have a look at this very "popular" bug: CSCuo14511.

Re: 3850 Switch Stack won't auto upgrade newly added switch

CPU Usage doesn't look bad to me at all. 

 

Since CPU isn't high and that bug is related to CPU usage I don't see why that bug would apply and prevent auto upgrade of IOS from working.  

 

3850-Stack#show process cpu
Core 0: CPU utilization for five seconds: 10%; one minute: 11%; five minutes: 11%
Core 1: CPU utilization for five seconds: 1%; one minute: 2%; five minutes: 2%
Core 2: CPU utilization for five seconds: 2%; one minute: 3%; five minutes: 2%
Core 3: CPU utilization for five seconds: 0%; one minute: 3%; five minutes: 2%

Read between the lines:  Avoid using early release of 3.6.X because of the bug.  Kindly consider upgrading to the latest 3.6.X (if there is a "must" to use 3.6.X).

Check the graph: sh proc cpu h

Re: 3850 Switch Stack won't auto upgrade newly added switch

Some CPU cores show high historical utilization but others look ok to me (see below).  I'm not stuck with 3.6.x as this stack is just an access switch for a building and changing code shouldn't be an issue as the only features I am using are vtp, and trunking.  
 
What version would you recomend upgrading to?

Re: 3850 Switch Stack won't auto upgrade newly added switch

Hello

The easiest way would I guess to copy the new iOS off flash1/2 onto sw3

copy flash1:xxx06.03.06e.bin flash3:

 

verify /md5 flash3:xxx06.03.06e.bin

Re: 3850 Switch Stack won't auto upgrade newly added switch

That's what I just tried, however I think I may have made things worse as we were running in install mode and when I ran the software install command using the .bin file I received an out of space warning.  Before trying again I did a reboot on the 3rd switch and when it came back up it now shows the switches in bundle mode which makes me think the 3rd switch booted directly to the .bin file.  I'm wondering if I should take and format the flash-3: file sysem for the 3rd switch then re-run the software install on the .bin file for switch 3.  Not sure if this will put the other switches back into install mode though.  Any thoughts?

Re: 3850 Switch Stack won't auto upgrade newly added switch

Hello

If you haven’t the space on the flash3; then

I am sure you can make the space

Can you:

dir  flash1:

dir flash3;

 

If the above didn’t work tou could also just remove thr switch switch from the stack - erase the config and  install the new iOS and then re-add it to the stack

Re: 3850 Switch Stack won't auto upgrade newly added switch

I formatted the flash-3: on the 3rd switch to free up space and then tried to install the 3.6.6E IOS and received an error about unable to determine free memory on switch 3.  I'm trying to figure why that is occuring and where to go from here.  The 3rd switch is not in production yet, but the first 2 switches are, but I still don't want to reload the 3rd switch without any ios as it currently stands.  What can you recomend, is there a way to get rid of the memory error or bypass it and get the 3rd switch to the same version?

Re: 3850 Switch Stack won't auto upgrade newly added switch

Hello

Not had that before -however as you ah e now formatted the flash on sw3 and your receiving that error - I would now personally remove it from the stack and re-cable the remaining production switch so you ha e a full stack- ring then with sw3 I would try to  format it agiajn and re-install the iOS

I've seen this error message before.   This error message appears when the stack has a very high up time. Here's the fix:
1. Make sure the BIN files are in each of the switch members.
2. Reboot the entire stack.
3. Perform a "software clean force switch all".
4. Convert Bundle Mode to Install Mode:  software install file flash-1:IOS_filename.bin new force verb
5. [OPTIONAL] Reboot the stack.

I'm not stuck with 3.6.x as this stack is just an access switch for a building and changing code shouldn't be an issue as the only features I am using are vtp, and trunking.

The latest 16.6.X will do fine for a stack doing nothing but Layer 2.
To keep things simpler, STAY AWAY from 16.9.X and later.  This is because Smart Licensing is enabled is enabled starting from 16.9.X and later.
