Thanks Bob, that's good advice. So, before I open my case, I've currently got 3 SATA drives all the same model, so how do I know which one is plugged into which SATA connector on the motherboard? Is there a command I can issue which gives identifying info that includes the disk id AND the SATA connector number that it is plugged into?
If I type 'format' I get the following info: # format Searching for disks...done AVAILABLE DISK SELECTIONS: 0. c0d0 <DEFAULT cyl 20007 alt 2 hd 255 sec 63> /[EMAIL PROTECTED],0/[EMAIL PROTECTED]/[EMAIL PROTECTED]/[EMAIL PROTECTED],0 1. c1t0d0 <ATA-WDC WD7500AAKS-0-4G30-698.64GB> /[EMAIL PROTECTED],0/pci1043,[EMAIL PROTECTED]/[EMAIL PROTECTED],0 2. c1t1d0 <ATA-WDC WD7500AAKS-0-4G30-698.64GB> /[EMAIL PROTECTED],0/pci1043,[EMAIL PROTECTED]/[EMAIL PROTECTED],0 3. c2t0d0 <ATA-WDC WD7500AAKS-0-4G30-698.64GB> /[EMAIL PROTECTED],0/pci1043,[EMAIL PROTECTED],1/[EMAIL PROTECTED],0 Specify disk (enter its number): ^C # Disks 1, 2, 3 and 3 form my RAIDZ1 pool, but I don't see info relating to the SATA connector number (1 to 6, or 0 to 5 perhaps, as I have 6 onboard SATA connectors on the motherboard). And once a disk id (e.g. c1t0d0) is assigned to a disk, is it guaranteed never to change?
