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.

Note: The VIR OPEN-xdevices can also be called custom volume size (CVS) devices (e.g., OPEN-3-CVS). When formatting a VIR OPEN-xLU, use the number of cylinders defined for VIR minus seven (e.g., use 993 cylinders for a VIR device defined with 1000 cylinders). The cylinder size is: one cylinder = 15 tracks, one track = 96 sub-blocks, one sub-block = 512 bytes. Table 3-9shows the relation between block length and write available capacity per track. The actual data capacity per cylinder = (write available capacity per track) ⋅ (15 tracks).
