Hi, daemon folks! I hope this isn't FAQ or already in progress - but I wonder whether it is possible to turn off a scsi harddisk automatically after a certain time of no operation - recent ide drives can handle this. I know, *SOME* older scsi drives knew a vendor specific command which performed the same - but I tried this with my (newer) harddisks and it didn4t work :-( My question is: Can someone help me to find out the *RIGHT* scsi commands for my disks or is there some code in the scsi/filesystem stuff that I missed? I suppose turning off a scsi harddisk with the scsi(8) command and START/STOPUNIT crashes the whole system rather than reducing noise ;-) My configuration P100, NCR825 with ST31230N and Q Fireball on narrow cable running 2.1R. If it helps tell me to be more specific. ANY suggestions are welcome. Fare You Well! ---- I will not trust you, I, Nor longer stay in your company. Your hands than mine are quicker for a fray: My legs are longer though, to run away. William Shakespeare, A Midsummer Night`s Dream, 1596
