Hitachi MK-96RD647-01 manual Installing and Configuring the FX Volumes

Installing and Configuring the FX Volumes

The FX volumes are installed and configured during TagmaStore USP and NSC installation and configuration. The FX volumes should be dedicated to data exchange operations to avoid accidental overwriting or deletion of important data. The FXmto volumes (-B and -A) contain z/OS data to be transferred to open-system LUs. The FXotm volumes (-C and -A) contain open-system data to be transferred to z/OS volumes. The FXoto volumes contain the intermediate datasets for file transfers between open-system platforms. FX does not support concurrent access to FX volumes by the z/OS and open- system hosts.

To install and configure the FX volumes:

1.Determine exactly how many FXmto, FXotm, and FXoto volumes you will need for your multiplatform data exchange operations. The -A volumes can be used for FXmto, FXotm, and FXoto. The -B volumes are restricted to FXmto. The -C volumes are restricted to FXotm. The OPEN-xFMT volumes are restricted to FXoto. Make sure that the Hitachi Data Systems representative installs the desired number of each type of FX volume during TagmaStore USP and NSC subsystem installation and configuration.

Note: If you need to change the number of FX volumes, please contact your Hitachi Data Systems account team. Reconfiguring the FX volumes after TagmaStore USP and NSC subsystem installation may require reformatting entire array groups, depending on the microcode level of the subsystem.

2.Complete TagmaStore USP and NSC installation and device configuration as specified in the TagmaStore USP and NSC configuration guide for the applicable open-system platform (e.g., the TagmaStore USP and NSC HP-UX Configuration Guide, MK-94RD235).

–Device recognition and device files. For all open-system platforms, you must verify device recognition and device file creation for all FX volumes.

–File system/volume group. Do not create a file system or volume group on any FX volume, including the OPEN-xdevices which will be formatted for FXoto operations. FX volumes can only be accessed as raw devices by the open-system host using FAL/FCU (no mount operation).
