59.3.9.56 HSM MD5 Checksum

Action Description
The HSM MD5 Checksum T-workflow action allows you to select combinations of codec and media pools at a designated meta device and perform a validity check on the content before restoring the media content to the database.

Action Parameters
HSM_MD5_Checksum
Provide the required information to fulfil the validity check:
•Name: Give a name to identify the T-workflow action in HSM.
•Select Codecs: Select the type of codec to be checked.
•Select Source Mediapools: Select the media pool where the content originated.
•Select destination meta device: Select the final destination to which the media content would be restored.
•Priority: Set a priority for the T-workflow action, e.g. High, Normal or Low.
•Select HSM Server to perform restore: Select the HSM Server to execute the restore operation.

NB: The MD5 Checksum can be performed on LTO and Linear tape file systems (LTFS). The destination meta device parameter is not required if you do not want to distinguish the archives on different libraries.

How to use it
Before you start using the T-workflow action, launch the T-workflow designer module to include the action in the T-workflow.

Once the action is added to the T-workflow, HSM Headquarters will schedule the T-workflow action “HSM MD5 Checksum” to perform a validity check on mounted media.

Next, the HSM Data Pump would execute the scheduled operations in HSM Headquarters and update the MD5 Checksum status. You can view the MD5 Checksum status in the T-workflow Log.

At the end of the T-workflow action, you can also view the MD5 Checksum status from the Technical Data tab in MAM’s Media Library, where the files successfully passed the MD5 Checksum validity check is indicated with a green arrow in the MD5 Checksum column.
