Modifying a Disk-to-Disk Policy Class

Manual Disk-to-Disk Relocation

Creating a Disk-to-Disk Policy Class

source /usr/adic/.cshrc

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 -ioption (MinRelocTime), the default relocation time of seven days is used.

If only one affinity is listed with the -aoption, no relocation occurs because a destination affinity is not defined. The first affinity listed after the -aoption 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.
