firmware upgrade on Csco UCS c220 m3 failing

[hingole]

Iam trying to upgrade the cisco firmware to latest one for Cisco 220 M3s using ucs-c220-huu-2.0.8g.iso but the upgrade is failing while loading the the disk.

Iam using KVM console to upload the firmware ISO while looking at the background process(using f2 key).

I see below error 

~~~

dracut: Starting plymouth daemon 

/sbin/disco_platform.sh : platform identifier [UCSC-C220-M3S]

[: 250:C220: unexpected operator

/sbin/disco_platform.sh: platformstr=C220

[: 335: C220: unexpected operator

copying live image to RAM

(this may take few minutes)

it gets stuck there.

Greetings.

What is your current CIMC version you are upgrading from?

Have you tried doing a CIMC reboot (admin tab, utilities, reboot CIMC), and then rerun the HUU?

Are you on the same LAN as the CIMC, when you are connected via the vKVM/web interface?

Thanks,

Kirk

I have the same problem. Did you solve this?

Greetings.

Common issues we see impacting HUU upgrades:

• Existing CIMC memory leak.  Reboot the CIMC before booting into the HUU ISO.
• Low bandwidth between Web-browser where virtual KVM is running, and actual CIMC (i.e. over VPN)
• If using dedicated MGMT interface, check the upstream switchport to make sure the CIMC and switch didn't negotiate a mismatched config (100 half duplex), or see huge number of CRCs on connection.

Thanks,

Kirk..

Kirk, thanks a lot!

Recently I had the same problem and I fixed by rebooting CIMC and disabling network throughput throttle for the VM I was using to map the ISO file. I did both at the same time so I'm not sure which one did the trick.

Thanks
