Access point are not coming up after upgrade image of WLC

[Sunil Patil]

Hi,

I have AIR-WLC4402-50-K9 WLC i that current IOS is 7.0.98.218 and i upgraded with 7.0.116.0 IOS but after upgrading and reboot the WLC from 15 access point 3 access point are not coming up and 12 are coing up and working fine (4 1142 and 11 1131 series access point) 3 which are not coimg is 1131 series access point. when i login with console to 3 access point its rebooting 2 times and coming on ap: prompt.

In between that i reloaded the WLC one more time because from 15 acess point only 4 aceess point are came up and i also cleck the show boot on wlc its output is

7.0.116.0 (default)

7.0.98.218 (active)

so i reload  the wlc and checked out of 15 acess point now 12 acess point are up and still 3 are not. And i also checked the output of show boot command its

7.0.116.0 (default)(active)

7.0.98.218

So i things its because of when 2nd time i reload the wlc the remaining 3 access point are getting image from wlc but because of reload its connection should be loss and error loading flash error are coming on acess point.

After that i recover the IOS for access point and convert into autonomus and from autonomus convert into Leightweight Access point. I also attached the procedure for recover the ios of access poing

But my question is why this 3 access point are not coming up is this happen's after upgrading wlc can any one please send me Step by Step WLC S/W Upgrade' process and if this this happens some time please send me any doccument related to this.

Sunil,

     When you rebooted the controller did you do it from the Web GUI, the CLI, or did you physically reboot the controller? I believe and maybe incorrect but if your getting the ap:  < prompt > that means that there is no firmware on the unit. If you have restored these to functioning autonomous unit and then re-converted them to Lightweight and it's still happening then we need to look at a debug output of what is happening when those AP's attempt to join the controller.

The capture you attached shows that it appears to join the controller and get a config, but are you saying that when it reboots again it stops working?? the other thing I would reccomend is clear out the flash memory since your capture shows the possibility that there are several copies stored there.

Hope this helps.
