NFS problem

Hello

This is not 100% Solaris related problem, but I hope that someone more
experienced with RPC can help me. In a fact I am writing this question
here because everything is working fine with file system shared on
Sun/Solaris box, while it is not working with file system shared on
EMC/Celerra.

I am using disk less clients that boots RedHat 8.0 over BOOTP and mount
root file system over nfs. But I got stuck with mounting root file
system shared on EMC/Celerra. Everything works fine when root file
system is shared on SUN/Solaris box.

This is how boot process ends when I use Celerra as NFS server :

Looking up port of RPC 100003/2 on aaa.bbb.ccc.xxx
Looking up port of RPC 100005/1 on aaa.bbb.ccc.xxx
call_verify: server accept status: 5
call_verify: server accept status: 5
call_verify: server accept status: 5
RPC: garbage, exit EIO
Root-NFS: Server returned error -5 while mounting /BOOTP/redhat/8.0/
VFS: Unable to mount root fs via NFS, trying floppy.

This is how it looks (all options are same, except for NFS server IP and
share path, all files are identical on shared file systems) when root
file system is shared on SUN/Solaris :

Looking up port of RPC 100003/2 on aaa.bbb.ccc.yyy
Looking up port of RPC 100005/1 on aaa.bbb.ccc.yyy
VFS: Mounted root (nfs filesystem).

I can mount file system using command line "mount
aaa.bbb.ccc.xxx:/BOOTP/redhat/8.0 /mnt" shared on EMC/Celerra when
RedHat is up and running. I can access all files there - no problems at
all. The problem is only to mount root file system during OS boot.

Can you give any tip what is wrong and what are possible ways to fix it
  ? What is meaning for status 5? If I would know what exactly is wrong
- maybe I would be able to fix it. What are major diffrences between
Sun/Solaris and EMC/Celerra NFS shares ?

Any help would be highly appreciated.

With best regards
Martynas
