today I tried to update WLC 5008 to software version 126.96.36.199. 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:188.8.131.52 to 184.108.40.206 failed. Failure Cause:Unable to open image tar file..
AP with MAC: xx:xx(xxxx) upgrade image from verion:220.127.116.11 to 18.104.22.168 failed. Failure Cause:Error access flash file system..
// Sorry for my bad English, I hope my problem is understandable.
