NSS volumes on OES Linux SP2
iManager 2.6 with latest storage plugins running on another OES Linux SP2

When trying to manage the NSS volumes in iManager 2.6 the following error comes up:

File Protocol error occurred: cannot open the NSS version file on the selected server. The NSS software may not currently be running on this server.

We are trying to set user quotas on the volume and as far as I know this can only be done from within iManager/ConsoleOne or is there a Linux NSS util that can do the job? Anyhow this error should be resolved.
