6Save and close the configuration file.

7Use cvadmin to start the file system by typing the following:

/usr/cvfs/bin/cvadmin

snadmin> start <file_system_name> snadmin> activate <file_system_name> snadmin> select <file_system_name> snadmin> show

8Mount the file system by typing the following: mount -t cvfs <file_system_name> <mount_point>

For example: mount -t cvfs snfs1 /stornext/snfs1

9Create an affinity/directory association by typing the following:

/usr/cvfs/bin/cvmkdir -k <affinity_name> <directory_name>

For example: /usr/cvfs/bin/cvmkdir -k data1_aff /stornext/snfs1/ video_data

This associates all data written to /stornext/snfs1/video_data with stripe group Data1 and, therefore, disks CvfsDisk2 and CvfsDisk3.

Creating a Disk-to-Disk Policy Class

Use this procedure to create a disk-to-disk-specific policy class. You must have at least two affinities configured to create a disk-to-disk policy class.

Before initially executing any StorNext command line programs, you are required to source either the .profile or the .cshrc file. This will update the user environment with the StorNext environment variables.

•If you are running sh, ksh, or bash, type:

. /usr/adic/.profile

•For all other shells, type:
