In general, yes, you should worry about it. I would keep a close eye on the drive. Look for any more error messages. If you keep getting error messages, you may want to call IBM and inquire about it. They may be able to tell you what part of the drive "field replaceable unit 1" is. If they would put their manuals on their web site like Quantum and Seagate, you might be able to find out for yourself. > Here is the relavent part of my dmesg: > > ahc0 <Adaptec aic7895 Ultra SCSI adapter> rev 4 int a irq 12 on pci0:20:0 > ahc0: aic7895 Wide Channel A, SCSI Id=7, 32/255 SCBs > ahc1 <Adaptec aic7895 Ultra SCSI adapter> rev 4 int b irq 11 on pci0:20:1 > ahc1: aic7895 Wide Channel B, SCSI Id=7, 32/255 SCBs > > Sending WDTR! > (probe20:ahc1:0:5:0): Sending SDTR!! > da0 at ahc1 bus 0 target 5 lun 0 > da0: <IBM DGHS09U 0350> Fixed Direct Access SCSI3 device > da0: 40.0MB/s transfers (20.0MHz, offset 8, 16bit), Tagged Queueing Enabled > da0: 8748MB (17916240 512 byte sectors: 255H 63S/T 1115C) > > I just have the one scsi device. You might want to check and see if it is running too hot. Here's a script that might do that, depending on whether your firmware supports it. (I've tried it on the 18G version of that drive, with firmware version 03B0, and it works fine.) ======================================== #!/bin/ksh TEMPC=`camcontrol cmd -n da -u 1 -c "4D 0 76 0 0 0 0 0 20 0" -i 32 "s9 i1"` TEMPF=`echo " 2 k $TEMPC 9 * 5 / 32 + p" | dc` echo "The temperature is: $TEMPF F" ======================================== I think the default temperature threshold (before it starts spewing errors) is 60C. Ideally, though, you'll want to run a good bit cooler than that. You'll need to change the '-u 1' above to '-u 0' for your drive.
