I got this message:<br />“unable to install log files”<br />“errno=13”<br /><br />After that I tried to reload my system but i got stuck on "Status 90: Loading Boot Loader". After reading some documentations I assume that the problem is in my BIOS which got corrupted and I suspect this is because the upgrade process because from what I know, upgrading your NX-OS also means upgrading the BIOS. CMIIW.<br /><br />But since my upgrading process failed at the very first step (if i didn't forget, it failed on the uncompressing image file step) I assume that the BIOS didn't changed and I have tried to check my NX-OS version after those two attempts and found that my NX-OS version still at 6.1(1) which convince me that the upgrade process really really failed.<br /><br />I have tried to ask this before to Michael McNamara but unfortunately he never experienced the same problem like mine so he can't give me any advice. Can you help me in this matter? or maybe give me some clues to help me troubleshooting this problem. <br /><br />I have plan to contact Cisco TAC support on tommorow Monday, but I think before doing that, I have to try to figure out what's the root of this problem.<br /><br />I hope you can help me in this matter.

Also be aware that ISSU checks for network stability and won't perform if STP TCNs are being received either.
