3-22 Preparing for Cross-OS File Exchange Operations

Hitachi USP V Cross-OS File Exchange User’s Guide

Creating FXoto Volumes Using the FMT Utility

After the FAL/FCU software has been installed on the open-system host(s),

you can format the FXoto volumes using the FX Formatter (FMT) utility. This

enables you to allocate FXoto intermediate datasets. The FMT utility for UNIX

is a UNIX command executed from the UNIX command line. The FMT utility for

Windows 2000/2003/Windows NT is a GUI.

Note: FCU version 01-01-42 or later is required for the FMT utility.

The FX FMT utility defines the size of the OPEN-x volume in cylinders. The

maximum number of cylinders allowed by FMT is shown in

Table 3-8.

Note 2: XX = 1 or 2; YY,x = number; ZZ<2x

Note 3: For Solaris, the data cylinder must be less than or equal to 32767.

When using a LUSE volume, the geometry parameter is different, so the

number of cylinders should be calculated as follows:

Cylinder (specified to FAL formatting) <= (A*B*C) / (15*96) – 5

A: Head (Geometry parameter)

B: Block/Track (Geometry parameter)

C: cylinder (Geometry parameter)

Note 4: Vc = OPEN-V cylinder value (MAX.:49160 cylinders using FAL)

The FMT utility can be used on standard-size OPEN-x volumes and on Virtual

LVI/LUN (VIR) volumes.
