Unable to pre download images from WLC

[xsturma01]

Hi,

today I tried to update WLC 5008 to software version 7.6.120.0. Everything went ok, but when I tried to predownload images to AP, some of the AP's failed during the predownload operation. Predownload was completed successfully to all (36) AIR-CAP1602I-E-K9 AP, but all (40) AIR-CAP2602I-E-K9  failed. The reason of failure is following:

AP with MAC: xx:xx(xxxx) upgrade image from verion:7.4.110.0 to 7.6.120.0 failed. Failure Cause:Unable to open image tar file..

and then 

AP with MAC: xx:xx(xxxx) upgrade image from verion:7.4.110.0 to 7.6.120.0 failed. Failure Cause:Error access flash file system..

Any advices?

Thanks. M.

Maybe the APs were loaded with MESH IOS?

I had the same issue: CISCO TAC toild me it's cisco bug on 7.6.120.0, that causes predownload issue with 2600 series AP's.
