VOLSER reconciliation

If you have updated VOLSER data in the HCM configuration in stand-alone mode, there might be a mismatch between the VOLSER data in an HCM configuration file and its corresponding IODF on the host.

The next time you open your configuration file in HCM in online mode by using Open... or Open Special... from the File menu, differences between the VOLSERs stored in your HCM configuration file and those stored in the IODF will be detected. These differences must be unified, or reconciled, and so HCM will present the VOLSER Reconciliation dialog to resolve the differences before displaying the configuration diagram.

VOLSER Reconciliation dialog. This dialog is accessible from the HCM product and includes accessible help information.

The listbox contains one line for every device in the configuration for which the VOLSER value in the IODF on the z/OS host and the associated configuration file on the PC differ. On entry, all lines are preselected. But you can also work with only one or several devices by clicking on the appropriate lines.

Each line of the listbox shows the device ID, the device type and model, the serial number, and the VOLSER values for the configuration file and the current VOLSER recorded in the IODF on the host.

You can process the selected lines in the listbox as follows:

Click the button with the >> symbol to accept the HCM VOLSER value for the selected device. This button symbolically sets the direction of the VOLSER transfer for the selected lines and copies the HCM VOLSER values into the IODF.
Click the button with the << symbol to reject the HCM VOLSER value for the selected device. This button symbolically sets the direction of the VOLSER transfer for the selected lines and copies the IODF VOLSER values into the HCM configuration file.

Once a line has been processed, the selected lines are grayed and a >> or << symbol is inserted between the HCM VOLSER value and the IODF VOLSER value.

To unprocess your selection you can use the Reset button to mark all the lines in the listbox as requiring processing again. The lines can now be reprocessed again.

When you have processed every item in your listbox, click on the OK button. HCM then updates the local and/or the remote database with the accepted VOLSER changes.

Note: HCM offers a "Prime the IODF with Sensed Data" utility in the Utilities menu. Using this utility, sensed data can be stored in the IODF. See Priming the IODF with sensed data for details.
