I have a NM-WAE running WAAS software version 4.0.17.b.14. I have ticked the box in the GUI to enable disk encryption and rebooted the device a couple of times, but the disk is still not encrypted (I checked using show disk detail). If I check that immediately after a reboot the output reports that the disk is not encrypted. If I wait a few minutes and check again it usually says "Disk encryption feature is disabled" (and checking the running config shows that there is no disk encryption command). If I wait a while (5 - 10 minutes) it reports that Disk encryption is currently disabled, but will be enabled after reload." If I reload the module again I get the same result. Waiting over a weekend makes no difference (so it is not a matter of just waiting).
I have tried deleting it from the Cisco WAAS configuration manager and de-registered it and added it again. That made no difference. I also tried making the change via the command line and got the same result. The device is currently talking to the CM box (when I do a show cms info it shows synchronisation times within the last 10 minutes every time I look). According to the documentation the only things that I need for encryption to work is a working link to CMS and a reboot. Does anyone have any other ideas?
Thanks in advance,
