I have a Novell Netware 6 Server with Support Pack Revision 05 installed

I have 13 drives in an array configured as 1 volume

I just started receiving the following error
NSS-2.70-5008 Volume Server_Name/Volume had an error
(20012(nameTree.c{45})) at block 38144597(file block - 38144597) (ZID 6).

My drives look fine physically

Can I stop the broadcast message from going out to all users and what is
my problem and how can I fix it?

I know it's a lot to ask, but please HELP!
