Error during vault creation

I was able to install the slicestor and the accessor.  They were both installed on the same server.  When trying to create my first vault, I got an error.  The error is stated below:

[root@testsrv1 bin]# ./dsnet-create-vault --name="dsnetvault" --descriptor="/usr/local/bin/dsnet-accesser/conf/vault-descriptor.xml"
Error creating vault on access server
Could not create vault object
Could not create vault object
Could not create vault object
Could not create vault object

below is my vault-descriptor.xml file:

[root@testsrv1 bin]# more /usr/local/bin/dsnet-accesser/conf/vault-descriptor.xml

Question on configuring the vault-descriptor.xml:

1.  If I leave it as the default 8(num-slices) X 6(threshold) configuration do I change the port value from 5000-5007?

2.  If I leave the file as the default, does it mean I'm running multiple intances? do I have to comment line #4 on the wrapper-server.conf file? 

Any help would be appreciated.
