AP3802 8.5.135 => 8.10.121 : "no space left"

[michael14]

Hi,

my AP3802 are running with 8.5.135, when trying to update them via mobility express update function i can see that all APs successfully download the new tar via tftp but fail with "no space left".

Even fully clearing /storage or flash: doesn't make a differance. Maybe because flash is just 57.5M and the tar 66.2M (AIR-AP3800-K9-ME-8-10-121-0.tar):

Filesystem Size Used Available Use% Mounted on
flash 57.5M 164.0K 54.3M 0% /storage

Even downgrading to 8.2.161.0 capwap (ap3g3-k9w8-tar.153-3.JC8.tar) as some on the net suggest doesn't work out.

Also other versions like 8.8.100 (AIR-AP3800-K9-ME-8-8-100-0.tar) show "no space left"

Any idea on how i can update the APs?

have you tried to load image from tftp using the mode button?

or convert mobility express

[michael14]

sure, neither mode button (>20s) nor 'ap-type mobility-express tftp://<tftp server ip-address>/<filename of TAR file with path from root on the TFTP server>' worked out, both load the image which seem not to fit into storage...
guess i'll stay with 8.5.135 :-/

You need to extract the tat file and then use the appropriate image. That is why it is failing.

[michael14]

Thats what i did with the e.g. AIR-AP3800-K9-ME-8-10-121-0.zip

the corresponding file inside the dir is ap3g3, same as AIR-AP3800-K9-ME-8-10-121-0.tar

Inside both archives are the following files:

- btldr.img

- file_hashes 

- final_has

- info

-info.ver

-iosap_info

- me_image

- part.bin (=> 63,5MB > flash size)

But, part.bin is bigger than internal flash storage

These files are also available on tftp in root folder, how do i update the APs with these files? One by one? Or is ist enough to transfer part.bin, but how do i tell to install oder flash?

Sry, I'm a bit lost...thank for your help so far

On the WLC you need to install 8.8.x first, before going to 8.10. I wonder if that is also valid for the ME APs.
Can you show a dir of the AP? It's possible that some old directories were left over, with (large) files inside.

[michael14]

Hi, looks like I've to set up an WLC :-/ but all it does is like ME does, tell APs to use tftp to downlad tar...

Here the output of show flash:

but it also fails when flash is completely empty:

flash                    57.5M    164.0K     54.3M  0% /storage

[michael14]

sadly not, guess i've to setup an wlc

output of dir flash
Filesystem Size Used Available Use% Mounted on
flash 57.5M 164.0K 54.3M 0% /storage

looks like it's simple to less space in flash

I had the same problem when tryed to upgrade directly to 8.10.x.

The workaround I used was to convert AP to ME 8.5 using only the ap3g3 image extracted from the .tar file, and then upgrade to ME 8.10.

made it!

archive download-sw /reload tftp://[IP]/ap3g3-k9w8-tar.153-3.JJ1.tar
archive download-sw /reload tftp://[IP]/AIR-AP3800-K9-ME-8-10-121-0/ap3g3

thank to all!!! in particular Jesus :-)

[wujunwang]

Thank you so much, it worked for me.

[cquesadacyl]

Jesus, I have 2 AP3802i and I am new using this model. I try to convert to ME but have the same issue, not enough space. Both have 8.5.103 version. Could you help me step by step?

[JPavonM]

@cquesadacyl ths is detailed upgrade process:

Download Lightweight AP tar file (ap3g3-k9w8-tar.153-3.JJ1.tar) and upgrade the AP with:

archive download-sw /reload tftp://[IP]/ap3g3-k9w8-tar.153-3.JJ1.tar

Download latest Mobility Express 8.10 train version with all zipped AP images (AIR-AP3800-K9-ME-8-10-171-0.zip);

Extract ALL fileS from inside zip; update AP with ap3g3 image using:

archive download-sw /reload tftp://[IP]/AIR-AP3800-K9-ME-8-10-171-0/ap3g3

Download latest 8.5 Mobility Express image (AIR-AP3800-K9-ME-8-5-182-0.tar) and upgrade AP with:

ap-type mobility-express tftp://[IP]/AIR-AP3800-K9-ME-8-10-171-0.tar

Reload AP and after booting check version with show version command to validate:

The AP Image type is now MOBILITY EXPRESS IMAGE
The AP Configuration is now MOBILITY EXPRESS CAPABLE

How do I get the Release 15.3.3-JJ1 if I do not have a contract?


Could I get a contract? How do I get the contract? I got the Aps as second hand.
