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).

Note: The write available data per track includes the four-byte RL information and four-byte BL information for each record. When transferring variable- length records, make sure to take this extra required space into account.

WARNING: The FX FMT utility erases all data on the OPEN-xLU being formatted. If necessary, back up the data on the OPEN-xLUs prior to FMT formatting.
