Firmware update fails 5406zl

[Brian_O]

I'm trying to update my firwmare from 14.83 to 15.08.  My Bootrom is 12.22 so there should be no issues.  I always get invalid image or corrupt file message and the update fails.  Any thoughts?

Thanks,

Brian

Well, anytime I have had that issue, I re-downloaded a "fresh" copy of the image file and tried again...generally that worked.

How do you update the switch(es)? By web-gui or tftp or what?

I recently upgraded 2 5412zl's and 4 5406zl's and I had this problem on 2 of them. The solution was simply to reboot the switch before upgrading.

So no I always reboot a switch before i start the upgrade-process and have no problems.

I always execute the commands via CLI, and for ProVision, Comware5, and Cisco, do image updates via tftp.

I cannot remember ever having to reboot a switch before a software update.

I have experienced what the original poster has, but when I d/l the image again and tried, it worked.
