Use the fsaddclass command to create a new policy class by typing the 

following:

/usr/adic/TSM/exec/fsaddclass <policy_class_name> -a 
<default_affinity> <destination_affinity> -i <relocation_time_in_days>

For example: /usr/adic/TSM/exec/fsaddclass dtdclass1 -a Aff1 Aff2 -i 1
The list of affinities includes the same affinities that were defined through 

the GUI. 
If you do not use the -i option (MinRelocTime), the default relocation 

time of seven days is used.
If only one affinity is listed with the -a option, no relocation occurs 

because a destination affinity is not defined. The first affinity listed after 

the -a option is the default affinity.

Use the fsmodclass command to modify an existing policy class by 

typing the following:

/usr/adic/TSM/exec/fsmodclass <policy_class_name> -a 
<default_affinity> <destination_affinity> -i <relocation_time_in_days>

For example: /usr/adic/TSM/exec/fsmodclass dtdclass1 -a Aff1 Aff2 -i 1

Use the fsrelocate command to perform manual disk-to-disk migration. 

You can use this command to relocate a file from the current affinity to 

another affinity, provided it meets these criteria:

• The file must be a non-zero sized file
• The file cannot be truncated
• The file cannot be specifically excluded from relocation via the 

fschfiat

 command

For example:

/usr/adic/TSM/exec/fsrelocate /stornext/snfs1/data1/file1 -a Aff2

In the previous example, the file /stornext/snfs1/data1/file1 will be 

relocated to affinity Aff2.
