While we are at it ... could you explain to me, why I can't move harddisks between different flavours of AHA2940 controllers ? I have two scsi controllers: AHA 2940U and AHA 2940 I wasn't able in the past, to boot one disk with a FreeBSD installation created on controller one to boot on controller two. ahc0: <Adaptec 2940 Ultra SCSI host adapter> rev 0x00 int a irq 17 on pci0.13.0 ahc0: aic7880 Single Channel, SCSI Id=7, 16/255 SCBs ahc0: waiting for scsi devices to settle scbus0 at ahc0 bus 0 ahc0: target 0 Tagged Queuing Device sd0 at scbus0 target 0 lun 0 sd0: <IBM DORS-32160 WA6A> type 0 fixed SCSI 2 sd0: Direct-Access 2063MB (4226725 512 byte sectors) sd0: with 6703 cyls, 5 heads, and an average 126 sectors/track st0 at scbus0 target 4 lun 0 st0: <TANDBERG TDC 4222 =07:> type 1 removable SCSI 2 st0: Sequential-Access density code 0x0, 512-byte blocks, write-enabled cd0 at scbus0 target 6 lun 0 cd0: <TOSHIBA CD-ROM XM-5701TA 3136> type 5 removable SCSI 2 cd0: CD-ROM can't get the size ahc1: <Adaptec 2940 SCSI host adapter> rev 0x03 int a irq 16 on pci0.14.0 ahc1: aic7870 Single Channel, SCSI Id=7, 16/255 SCBs ahc1: waiting for scsi devices to settle scbus1 at ahc1 bus 0 ahc1: target 1 Tagged Queuing Device sd1 at scbus1 target 1 lun 0 sd1: <IBM DORS-32160 WA6A> type 0 fixed SCSI 2 sd1: Direct-Access 2063MB (4226725 512 byte sectors) sd1: with 6703 cyls, 5 heads, and an average 126 sectors/track ahc1: target 2 Tagged Queuing Device sd2 at scbus1 target 2 lun 0 sd2: <IBM DORS-32160 WA6A> type 0 fixed SCSI 2 sd2: Direct-Access 2063MB (4226725 512 byte sectors) sd2: with 6703 cyls, 5 heads, and an average 126 sectors/track Probing for devices on the ISA bus: -- Andreas Klemm http://www.FreeBSD.ORG/~andreas What gives you 90% more speed, for example, in kernel compilation ? http://www.FreeBSD.ORG/~fsmp/SMP/akgraph-a/graph1.html "NT = Not Today" (Maggie Biggs) ``powered by FreeBSD SMP'' To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
