Linux OES - File Protocol error occurred: cannot open the NSS version file on the selected server

After a fresh Linux OES SP2 installation I receive:

Error: 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.

when I try to manage NSS using iManager.

NSS is installed. The server has two RAID5 arrays - the first one (300GB) is
used for the OS - the second one will be dedicated to NSS.

Any ideas?
