Waiting 15 seconds for SCSI devices to settle *groan*

the most antiquated SCSI peripherals that actually do need 15 seconds 
;) ) If yes, I'll just shut up about this.


my cd writer does.  but i have the delay set to 3 secs, and it just 
reports in later, no big deal.  so i'm basically for reducing this timeout.

Still needed for large arrays, when staggered spin-up is used to reduce 
PS load.
Modern drives generally are designed to ramp-up more gently anyway,
so using it is not always required.

As an inveterate SCSI user, I would still vote for shortening the time 
to *zero* anyway.
The diminishing universe of SCSI users may then rebuild if/as/when 
needed with a longer period.

Optioning the SCSI device (HDD, anyway) to start at power-ON means it 
will usually be
ready well before the MB BIOS and other devices have finished POST, so 
it is seldom an issue
even with multiple hardware RAID.

YMMV,
