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.
Note: The VIR OPEN-x devices can also be called custom volume size (CVS)
devices (e.g., OPEN-3-CVS). When formatting a VIR OPEN-x LU, 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 3-9
shows the relation between block length and write available capacity per track.
The actual data capacity per cylinder = (write available capacity per track) ×
(15 tracks).
