We also use force perfect terminators just to be sure evetrything works smoothly. System has complained a lot of drives 0:0 0:1 0:2 and these we had replaced twice also used low level formatting. ---clip clip--- Setting Device Termination Power All of the SCSI drives connected to the DAC960P Series should be shunted to apply power on the SCSI TERMPWR line, as well as having any of their builtin terminators disabled or removed. It is important that all drives supply termination power, so that power is applied to the SCSI bus even if drives are removed or replaced. The same rules also apply to non disk SCSI devices connected to any of the DAC960P Series SCSI channels. -- SUN Microsystems Oy PL 112, Lars Sonckin kaari 12, 02601 ESPOO, Finland Tomi Vainio (System Support Engineer) +358 9 52556300 hotline email: Tomi.Vainio@Sun.COM +358 9 52556252 fax To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
