User bytes/sector (ub/sct)
256 - 744 (even number of bytes only)
Sectors/logical block (sct/lba)
1-8
The lowest sct/lba that satisfies the following rules is used...
1. Block Length is evenly divisible by a number 2-8.
2. Quotient of previous equation is evenly divisible by 2.
3. Quotient must be
≥
256 and
≤
744.
User bytes/logical block (ub/lba)
256 - 5952 (See rules for determining sct/lba above for determining sup-
ported ub/lba values.)
Sectors/track (sct/trk)
(See Table 1 on page 13 or contact an IBM Customer Representative
for other block lengths.)
