Unity 680F failed upgrade on one node (0x6000014) / 'Peer_Did_Not_Upgrade'

Question

Hi,

Trying to get a Unity upgraded from 5.3 to 5.5, and everything looked to be going perfectly until it started on the second node. It failed to update and I'm not sure what I can do from here. Uemcli won't let me cancel the operation, and when I resume/retry it, it just fails again. What else can I try? I'm afraid to attempt a reboot as I'm not sure what the status will be when it comes back alive. This is not yet in production so anything destructive is just fine (as long as I can get the license file off first)
TIA

Hi,

Thanks for your question.

Are there any other errors? Do the LEDs on the SP show faults? Dell EMC Unity: SP LED status indicators - Understanding colors and states for troubleshooting | Dell US

Let us know if you have any additional questions.

you can check upgrade log to find what wrong with the upgrade process.

Mtexter · Answer

One SP shows faulted (the one which failed the upgrade), the other is alive and well with the white 'do-not-remove' hand illuminated.  I will dive into the logs and see what I can glean from that.

Mtexter · Answer

@tianchou​ doesn't seem to show much.  /event/log show -severity critical shows nothing, error shows just 'the software upgrade failed', and warning shows me 4 messages:  I'm not sure how useful any of that is, but I'm getting nowhere.

Mtexter · Answer

@DELL-Josh Cr​ the LED behavior is indicating this node is in service mode (SPA)

I also have no options to do anything other than retry the upgrade from the GUI (which fails after a minute or two). It won't let me close the upgrade wizard, so I guess the only way forward is via the CLI.

You can try running it from cli https://www.dell.com/support/kbdoc/en-us/000022755/dell-emc-unity-how-to-upgrade-dell-emc-unity-oe-code-user-correctable

@DELL-Josh Cr​ No dice.  SSH is disabled by default, and this is the message I get when trying to enable it:'The system was unable to connect to the storage server. (Error Code:0x100000a)'

DELL-Josh Cr · Answer

You may need to direct connect to the serial port on the SP https://www.dell.com/support/kbdoc/en-us/000208170/dell-unity-how-to-connect-to-unity-xt-platforms-via-serial-connection

PeteM3 · Answer

Hello, @DELL-Josh Cr , I am helping @Mtexter with this, this Unity does not appear to have the option for a direct connection via serial port. It is a Unity 650F not a 680F.

DELL-Josh Cr · Answer

In that case you are going to need to call phone support so they should be able to get it to bypass the health check so the upgrade can run.

Mtexter · Answer

@DELL-Josh Cr​ does that require a support contract?  We do not have one.  If it costs more than $0 we can't do it with this unit unfortunately.

DELL-Josh Cr · Answer

Yes, it requires a support contract. You can try clearing service mode and rebooting the SP. svc_rescue_state -c svc_shutdown -r
