Implementation depends upon which type of RAID. What manufacture of the hardware, or the Linux software. Should I kow how to implement Linux software RAID when I am using Adaptec hardware? How about if I am using the IDE RAID with the binary only modules? This is where I have a problem on testing. If the questions relate to levels of RAID, eg: What is level (choose one -> 0, 1, 4, 5, or 10 ) RAID a: mirroring b: striping c: mirroring & striping d: non of the above (Lots of questions can be made that are generic, just no specifics such as how do you configure the software RAID driver in the 2.2.x kernels.) Then it makes sense to do this at L2, however to ask how to configure software RAID as currently in the kernel is not appropriate at L2 it could be a test at L3. As of today in the 2.2.14 kernel I count 3-4 RAID cards and software RAID also. This does not include SCSI to SCSI RAID nor the IDE RAID systems. > > DM>but I disagree that we should test for specific RAID information, hardware > DM>or software. > > Should we *ever* ask specific stuff...? e.g. (now here's a silly question): > > Is there a Linux driver in the kernel for the DAC960? Perhaps it is a silly question but it does make the point what is here today may not be tommorow and what is not here today may be here tommorow. Do you make the test specific to a kernel? Bringing it all back together. I feel that generic questions are good at L2 but for specific hardware and software methods those are tests for L3 and for some things you just don't test at all (SCSI to SCSI and IDE). The market will either provide training or will ask specific questions.
