Upgrading the DMF software is essentially the same procedure as the one described in Procedure 5-1.
You need to be aware of the following differences from an initial installation:
When you start to edit the configuration file for the new version of DMF, you are prompted as to whether you want to use the existing configuration file or one of several sample files.
When you select Activate to make the new revision of DMF active, you may receive a warning that the current version of DMF is running and will have to be stopped. You must click OK if you want the activation to continue.
After installing and testing a new revision of DMF, you most likely will want to remove the previous revision of DMF. Select the previous revision using the Selected Version: list box, then select Remove. You will be prompted for confirmation before the revision is actually removed. If the revision being removed is the active revision, then DMF will be stopped and all symbolic links will be removed.
Before upgrading to a new release, please read the following information and be sure that your site is able to accommodate the process. Failure to do so can cause major problems when the DMF is initialized.
DMF supports both OpenVault and the Tape Management Facility (TMF). You must acquire these facilities before you can upgrade. Support for the tape MSP Autoloader API has been dropped.
TMF is available to all DMF licensed customers for no charge. If you want TMF, order product SC4-TMF-XL. This will grant TMF, free of charge, to any existing DMF-licensed customers.
DMF is licensed for several different architectures based on the number of CPUs, and DMF does enforce a node locked license. However, it does not enforce licenses based upon the size of the machine.
