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.
