while I follow the document of iFolder3 until
6.2 Configuring the iFolder Enterprise Server
iFolder data, use iManager to create the NSS volume, then create a
directory on the volume.
For information, see Managing NSS Volumes in the Open Enterprise Server.

so I goto "Managing NSS Volumes" document to do the rest until
"13.3 Creating and Configuring Unencrypted NSS Volumes with iManager"
In iManager, click Storage > Volumes.
Then I enter into the Wizard but while I new a pools,
a error occured as below

Error: CIMOM error occurred: cannot write to the given file.

Please help!
Thanks a lot!
