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 HP service representative installs the desired number
of each type of Data Exchange volume during the storage system installation and configuration.
NOTE:
If you need to change the number of Data Exchange volumes, contact your HP service
representative. Reconfiguring the Data Exchange volumes after storage system installation
may require reformatting entire array groups, depending on the microcode level of the
storage system.
