A problem with 4.8 reported by myself and Aaron D. Gifford. Anyone in -stable who knows more? ******** I'm assembling a Compaq 1850R with attached storage system. For the built in scsi controller (sym), there are three drives internally on channel 1 + 5 drives externally on channel 2. During boot, I can see all disks being identified first by the machine itself and then in the early part of the process (something scrolls by talking about BIOS drive numbering). However, the result is not 8 drives but 5 in total in a mix between the channels, see below. da0 at sym0 bus 0 target 0 lun 0 da0: <COMPAQ AB00931B92 3AS8> Fixed Direct Access SCSI-2 device da0: 40.000MB/s transfers (20.000MHz, offset 15, 16bit), Tagged Queueing Enabled da0: 8678MB (17773500 512 byte sectors: 255H 63S/T 1106C) da4 at sym1 bus 0 target 4 lun 0 da4: <COMPAQ MAB3091SC 0814> Fixed Direct Access SCSI-2 device da4: 40.000MB/s transfers (20.000MHz, offset 16, 16bit), Tagged Queueing Enabled da4: 8678MB (17773500 512 byte sectors: 255H 63S/T 1106C) da2 at sym0 bus 0 target 2 lun 0 da2: <COMPAQ AB00931B92 3AS8> Fixed Direct Access SCSI-2 device da2: 40.000MB/s transfers (20.000MHz, offset 15, 16bit), Tagged Queueing Enabled da2: 8678MB (17773500 512 byte sectors: 255H 63S/T 1106C) da3 at sym1 bus 0 target 3 lun 0 da3: <COMPAQ AB00931B92 3AS8> Fixed Direct Access SCSI-2 device da3: 40.000MB/s transfers (20.000MHz, offset 15, 16bit), Tagged Queueing Enabled da3: 8678MB (17773500 512 byte sectors: 255H 63S/T 1106C) da1 at sym0 bus 0 target 1 lun 0 da1: <COMPAQ AB00931B92 3AS8> Fixed Direct Access SCSI-2 device da1: 40.000MB/s transfers (20.000MHz, offset 15, 16bit), Tagged Queueing Enabled da1: 8678MB (17773500 512 byte sectors: 255H 63S/T 1106C) Aaron D.

Under 4.7, the sym driver would see all 5 SCSI drives. But after a CVSupdate and build/install of world and reboot, the machine failed to boot because the first drive, the root drive, was no longer visible to the kernel. The FreeBSD boot loader could still see the drive, but the kernel would never detect it. At first we couldn't figure out what was going wrong. After some hours including an attempt to install 4.8-RELEASE on another drive that also failed because of the disappearing drive problem, we reinstalled 4.7-RELEASE and have been running RELENG_4_7 since. I think our old system uses the NCR 875 chipset. Anyone know what changes between 4.7 and 4.8 to sym might be responsible for the disappearing drive trick?
