System : SS10 with SunOS 4.1.4

I just purchased a new Quantum -XP32150 SCSI drive and ran into a problem formatting it. The drive's rpm is at 7200 and, from my understanding, any Solaris 2.x or SunOS 4.1.3 or higher is able to handle this rpm. But when I tried to format the drive at rpm 7200, the system returned a "out of range" error. It did, however, accepted rpm = 5400. Where do I probe/change/reconfig to get it to accept rmp of 7200 ??? Does anyone have a working /etc/format.dat setup for this drive ?? Thank you much

Solutions:

1.

/etc/format.dat entry

disk_type = "Quantum-XP32150" \
    : ctlr = SCSI : fmt_time = 5 \
    : trks_zone = 10 : atrks = 0 : asect = 10 \
    : ncyl = 3850 : acyl = 2 : pcyl = 3907 : nhead = 10 : nsect = 109 \
    : rpm = 7200 : bpt = 64092

partition = "Quantum-XP32150" \
    : disk = "Quantum-XP32150" : ctlr = SCSI \
    : c = 0, 4196500

2.

The 3000rpm - 6000rpm limit is enforced only
if the parameters are entered interactively when running format.
In order to solve this problem you should enter data in the
/etc/format.dat file.

3.

format will only accept a maximum value of 6000, however the good news
is that the speed seting doesn't make any significant difference as far
as formatting or performance is concerned, so just set it to the max
value (6000) and enjoy your new disk...
