yes we have exported 3 files from the VNX and I can see them on the VNX DM, however from my Linux client I cannot mount them i.e. # mount 10.10.2.108/blackboarddb /blackboard”.

you are trying to mount NFS export from VNX on your local linux/unix client ?

make sure to add colon

mount 10.10.2.108:/blackboardb /blackboard

can you cd into /blackboard and "touch file.out" ?

ok after that we have had an Read /write issue trying to write data into these files..?

yes I can do that then we mount ed the files where we need them and in /usr/home/backup and we are now having permission issues...?

be more specific, what permission issues are you having, what have you done to fix permissions ? (chmod, chown)

we use Blackboard, we actually used to run in on Celerra but now it has been migrated to Isilon. Oracle DB was on block storage (VMAX) but content was on NFS exports. We did not do anything special on Celerra, just regular export where Blackboard server has root, read/write and access permissions.

do you know i there is an EMC white paper for deploying a VNX NFS share for the this application Blackboard this is an education application that uses oracle as a DB, and  is part of this NFS permissions error.

this sound great maybe you can help me here the client is running a procedure called oracle installer and we get this oracle issue has

[root@bbdata]# df

10.10.2.108:/blackboarddb  303200000       608 303199392   1% /usr/local/oracle/oradata

[root@bbdata oracle]# ll

total 16

[root@bbdata local]# chown oracle.oinstall oracle/oradata/

chown: changing ownership of `oracle/oradata/': Operation not permitted

can i just do the following

# chmod g+rw oracle/oradata/     to get this to run...?
