Editing the options file dsm.sys

Edit online

The options that you define in the dsm.sys file for the space management client affect automatic migration, reconciliation, and recall.

About this task

You must have root user authority to set the options in your dsm.sys file.

In the dsm.sys file, group your options into stanzas for each server that your client node contacts for backup, archive, and space management services.

Options are processed following this order:

  1. Options that are defined on the server with server-enforced client options (the client cannot override the value)
  2. Options that are entered locally on the command line
  3. Options that are defined on the server for a schedule
  4. Options that you enter locally in your options file
  5. Options that are received from the server with client options that the server does not enforce (the client can override the value)
  6. Default option values

For options that you can set in the dsm.sys file, see Options files reference

Note: You can specify both a default server and a migration server in the dsm.sys file. Use the defaultserver option and the migrateserver option. If you do not specify migration server and default server, the server that you specify in the first stanza of the dsm.sys file becomes the default server. If you specify a migration server with the migrateserver option, it overrides the server that you specify with the defaultserver option.

Procedure

  1. Obtain the server information from your IBM Storage® Protect administrator.
  2. Edit your dsm.sys file to include the server to which you want to connect for space management services.
  3. Assign a name to the server that you want to contact for space management services. For each servername entry, include a commmethod entry to specify the communication method to use for client and server communications.
  4. Issue a value for each option and remove the leading asterisk (*). You can specify options for more than one server.
