Hitachi MK-96RD647-01 manual Creating FXoto Volumes Using the FMT Utility, FMT Utility Values

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-xvolume in cylinders. The maximum number of cylinders allowed by FMT is shown in Table 3-8.

Table 3-8 FMT Utility Values

OPEN-V	not	not supported	not supported	65534	(min(Vc*n*128/
	supported				96-7,65534)
					(see Note 4)

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-xvolumes and on Virtual LVI/LUN (VIR) volumes.
