Hi guys, yesterday I've upgraded my -current from march to a current -current and now /sbin/camcontrol negotiate da4 -R 10 -qac >/dev/null 2>&1 is'nt working as expected anymore. I've used this, to keep an old bad Quantum drive working, that triggers SCSI Bus hangs if it is running at the full negotiated 20Mhz speed. With the current camcontrol, I can switch tagged queueing on and of, but I can't change the bus speed anymore: # /sbin/camcontrol negotiate da4 -R 10 -vac Current Parameters: (pass6:sym0:0:6:0): sync parameter: 12 (pass6:sym0:0:6:0): frequency: 20.000MHz (pass6:sym0:0:6:0): offset: 16 (pass6:sym0:0:6:0): bus width: 16 bits (pass6:sym0:0:6:0): disconnection is enabled (pass6:sym0:0:6:0): tagged queueing is enabled sym0: SIM/HBA version: 1 sym0: supports tag queue messages sym0: supports SDTR message sym0: supports 16 bit wide SCSI sym0: supports MDP message sym0: HBA engine count: 0 sym0: maximum target: 15 sym0: maximum LUN: 7 sym0: highest path ID in subsystem: 0 sym0: initiator ID: 7 sym0: SIM vendor: FreeBSD sym0: HBA vendor: Symbios sym0: bus ID: 0 sym0: base transfer speed: 3.300MB/sec Unit is ready New Parameters: (pass6:sym0:0:6:0): sync parameter: 12 (pass6:sym0:0:6:0): frequency: 20.000MHz (pass6:sym0:0:6:0): offset: 16 (pass6:sym0:0:6:0): bus width: 16 bits (pass6:sym0:0:6:0): disconnection is enabled (pass6:sym0:0:6:0): tagged queueing is enabled The controller is an Tekram DC39x (have to look at it for the correct model) and the disk is an QUANTUM VIKING 4.5 SCA 880R. J"org Wunsch (joerg@freebsd.org) can reproduce this. I have an new disk here, but I can't get the data from the old drive, the tape rewinds after BDR.
