Tivoli Storage Manager for Sun Solaris Quick Start


Creating a New Policy

The TSM default policy specifies how TSM manages client files. For example, it specifies that TSM retains up to two backup versions of any file that exists on the client (see Installation and Setup Results for details). Two versions may be enough for most clients. However, if some clients need the last ten versions to be kept, you can do either of the following:



Attention

Storing Directly to Tape

Under the default policy, client files are stored directly to disk. You can also define policies for storing client files directly to tape. In a copy group, simply name a tape pool as the destination. Note, however, that if you store directly to tape, the number of available tape drives limits the number of client nodes that can store data at the same time.

To create a new policy, you can start by copying the policy domain, STANDARD. This operation also copies the associated policy set, management class, and copy groups. You then assign clients to the new domain.

  1. Copy the default policy domain, STANDARD, to the new policy domain, NEWDOMAIN.


    Admin Command Line

    +--------------------------------------------------------------------------------+
    |                                                                                |
    |copy domain standard newdomain                                                  |
    +--------------------------------------------------------------------------------+

    OR
    Web Icon

    1. Select Policy Domains.
    2. Select STANDARD domain.
    3. From Operations, select Copy Policy Domain.
    4. Enter the domain information and Finish.

    This operation copies the policy domain, and all associated policy sets, management classes, and copy groups. Within the policy domain named NEWDOMAIN and the policy set named STANDARD, you have:

    For our example, you update only the backup copy group.

  2. Update the backup copy group by specifying that ten versions of backed up files are to be kept.


    Admin Command Line

    +--------------------------------------------------------------------------------+
    |update copygroup newdomain standard standard standard -                         |
    | type=backup verexists=10                                                       |
    +--------------------------------------------------------------------------------+

    OR
    Web Icon

    1. Expand Policy Domains, Policy Sets, and then Management Classes.
    2. Select Backup Copy Groups.
    3. Select the NEWDOMAIN STANDARD STANDARD STANDARD copy group.
    4. From Operations, select Update Copy Group.
    5. Enter the copy group information and Finish.
  3. Validate and activate the STANDARD policy set in NEWDOMAIN.


    Admin Command Line

    +--------------------------------------------------------------------------------+
    |validate policyset newdomain standard                                           |
    |activate policyset newdomain standard                                           |
    +--------------------------------------------------------------------------------+

    OR
    Web Icon

    1. Expand Policy Domains and then select Policy Sets.
    2. Select NEWDOMAIN STANDARD policy set.
    3. From Operations, select Validate Policy Set and then Finish.
    4. From Operations, select Activate Policy Set and then Finish.



    Trouble Shooting

    The following conditions result in warning messages during validation:
    • A destination storage pool is not a defined storage pool.
    • The default management class does not contain a backup or archive copy group.
    • The current ACTIVE policy set names a management class that is not defined in the policy set being validated.
    • The current ACTIVE policy set contains copy groups that are not defined in the named policy set.
    • A management class specifies that a backup version must exist before a file can be migrated from a client node, but the management class does not contain a backup copy group.

  4. Assign client nodes to the NEWDOMAIN policy domain by either updating existing client nodes or registering new nodes. For example, to update client node mercedes, do either of the following:


    Admin Command Line

    +--------------------------------------------------------------------------------+
    |update node mercedes domain=newdomain                                           |
    +--------------------------------------------------------------------------------+

    OR
    Web Icon

    1. Expand Clients.
    2. Select Client Nodes.
    3. Select the desired node.
    4. From Operations, select Update this Node.
    5. Enter the node information and Finish.

    TSM will now keep up to ten versions of backed up files for client node mercedes because it is assigned to the NEWDOMAIN policy domain.
