How do I reset SonicWall CDP device when disk is full?

I have a SonicWall CDP device that no longer allows me to connect with the Enterprise Console or an HTTPS browser.

I've connected a monitor, and the SonicWall appears to boot correctly.

I believe the problem is that the drive is full.  SonicWall online has no documentation on how to fix this and they want $800 to renew my support contract on this unreliable POS.

Anyone out there know of a solution?

Thanks!

Can you ping the IP address?  If it is full then the device should still allow you to connect - especially via HTTPS.

When connecting the monitor it will display the IP address of the unit.  Double check its right.

The device is pingable.  HTTPS as well as the enterprise manager client would not allow login.

SonicWall tech support spent about three hours remotely deleting data and log files.  Then they rolled back the firmware and finally were able to login.

I have not been back on site to test yet, so I'm not positive that it's resolved.

However, a couple of things that I've learned/revisited during this experience.

1. DO NOT EVER let the CDP drives fill completely.  There is NO WAY an end user can fix the problem, and if you don't have a support contract, you're SOL.

2. If you fill a Volume Quota, that backup process simply stops.  It doesn't delete old versions of files dynamically.  You have to delete ALL the old versions of files, thus erasing all of your backups.  I had the tech support person from Sonic change the number of old versions that the CDP stores.  I cut it in half.  Again, this is a setting that should be, but is not, user configurable.  You need tech support to connect to the box and make the change.

I like the concept behind the CDP, but even after having been out for a year, the firmware is still at Beta level, in my opinion.

Wait until November.  If you have a support contract with SonicWALL then you should be updated to the latest version which I believe has amazing updates that gives us more control over finalling making these devices really good.  Also in Q1 of next year a new version of CDP is out that allows you to inter-swap hard drives and make space up to about 28Tb.... not holding my breath!

Glad you're sorted out mate.

I know this has already been "answered" but you can login to the device locally if you have a mouse/keyboard/monitor.

I would HIGHLY recommend a decent knowledge of linux based systems before you attempt anything here.


Before it boots from grub edit the config, edit the line that starts with kernel, change 'ro' to 'rw' and add 'init=/bin/bash' to the end. Press return to save the changes then b to boot. From the shell you can go in and delete the old database files (it's the database change logs that fill up the drive, apparently they didn't count on the root partition getting full.)
