3-10 Preparing for Cross-OS File Exchange Operations
Hitachi USP V Cross-OS File Exchange User’s Guide
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-x FMT 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-x devices 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).
