I may have to give that a try. Only issue is our support contract expired in October - not sure what happened, but looks like we no longer have a relationship with the reseller, so we didn't get a renewal notice. Our RAM put us in contact with another reseller and the new invoice has been sitting on management's desk since December. I still have inventory of controllers, APs, and licenses, so not a big concern with any hardware failures at this point.
Canceled my upgrades last night, rebooted Airwave and created a smaller batch (3 controllers). They all downloaded from the FTP server and upgraded within 10 minutes.
Queued up 7 more and they just sat there. Looked at the controller info in Airwave and it had messages about errors with Telnet/SSH, along with confirmation of file transfer initiated. Confirmed settings (username and PW in Airwave), ability to SSH into controller (from laptop client, as well as from Airwave server via command line), FTP server up and accepting connections, and bandwidth to/from the site. Everything seemed fine. Upped the Telnet/SSH Timeout from 10 to 20 seconds and canceled first "stuck" controller from the job.
Went to bed.
Came in today and found they had finished (1 failed), but seemed to be almost exactly 2 hours between each controller (1:04, 1:06, 3:06, 5:07, and 5:08).
Seems like it works fine unless it hits a problem, then maybe it continues to try and doesn't fail and move on to the next for 2 hours? Can't seem to find any settings that would indicate any sort of wait time.
Tried again this afternoon - 3 controllers with no users. Less than 2 minutes per transfer and controllers upgraded without any issue. Again queued up 7 more. Have time stamps on those of 2:42, 2:45, 4:45, 4:47, 4:49, and 4:51pm.
The 4:45 is still "in progress" but have yet to see it hit the FTP server and I see this listed in the Recent AMP Device Events:
Fri Feb 8 16:45:11 2013 | System | Attempted firmware upgrade to 6.1.3.6 (6.1.3.6 for 6xx controllers) |
Fri Feb 8 16:45:11 2013 | System | Firmware Upgrade: Error transfering the file. |
Fri Feb 8 16:45:11 2013 | System | Telnet/SSH Error: command timed-out |
Fri Feb 8 15:45:10 2013 | System | Telnet/SSH Error: command timed-out |
Fri Feb 8 14:45:09 2013 | System | Firmware Upgrade: Initiating file transfer. |
Fri Feb 8 14:45:08 2013 | System | Needs firmware update |
The 7th controller says "in progress" but no time stamp, and nothing on the FTP server. Waiting to see if this will be like the others and complete 2 hours after the last.....guess I will know at 6:45.
I suppose I could do 3 at a time, but have a feeling this is not working as intended.....just not sure if it's something on our side. Can't find anything to lead me to believe it's an issue with Airwave, but just stumped on where to look.
Also looks like it doesn't matter if I use external FTP, Airwave will only process 1 transfer at a time? I guess the only reason to use external FTP would be to reduce traffic from the server - currently monitoring 540 devices at the moment......we don't use Airwave for configuration changes - mainly just for VisualRF. Everything is in Monitor-only.
Nothing critical with the upgrades, just trying to get up to the latest for the newer features (and have a box of APs that aren't compatible with 5.x.x code). If anything, this is giving me a reason to finally read the manual!
Will play around with it some more and see what happens. Will delete FTP server from group settings and just use AMP and see if it helps. If not I'll schedule some time to call support next week, or see if our SE is available to come in for some training.
