By the way, I found another case. First, some background. Some of our SCSI strings are double-ended, i.e., have two SCSI adapters on both ends. Due to physical constraints, they don't have external terminators. So they use the SCSI adapters' termination. This setup works pretty well normally, even when one machine is rebooted (Justin, thanks for fixing a problem of unexpected bus resets a few years back). However, if one of the machines is brought down (the "press any key to reboot" prompt), I start seeing timeouts on the other machine. === (da33:ahc2:0:1:0): SCB 0x17 - timed out in datain phase, SCSISIGI == 0x44 SEQADDR == 0x110 SSTAT1 == 0x2 (da33:ahc2:0:1:0): BDR message in message buffer (da33:ahc2:0:1:0): SCB 0x17 - timed out in datain phase, SCSISIGI == 0x54 SEQADDR == 0x110 SSTAT1 == 0x2 (da33:ahc2:0:1:0): no longer in timeout, status = 34b === I'm assuming this is because the termination went away. After I hit return to reboot it, the other machine recovers as if nothing happened. So, my question is: is it possible to keep the termination settings even when the operating system shut down, or is this just the way the adapters are designed?
