HP XP P9500 Storage - Manual (Page 96)

NOTE:
FCU version 01-01-42 or later is required for the FMT utility.
The FMT utility defines the size of the OPEN-x volume in cylinders. The maximum number of cylinders
allowed by FMT is shown in
Table 39 on page 96.

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)

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 (for example,
OPEN-3-CVS). When formatting a VIR OPEN- x LU, use the number of cylinders defined for VIR minus
seven (for example, 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
40 on page 96 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).
