I’m familiar with Irix’s confidence test for perriferals, I was wondering what tools Irix has to test a drives integrity or a JBOD raid device. 

I have purchased a few Medéa raids and was able to initialize and mount the raid devices with no issue, but I have no idea if there are any bad sectors.

If this is a hardware RAID then it presents itself to the IRIX system as a single block device. You can exercise it with 'fx'. Assuming your volume is SCSI ID2 on controller 1:

Code:

4# fx -x
fx version 6.5, Jul 20, 2006
fx: "device-name" = (dksc)
fx: ctlr# = (0) 1
fx: drive# = (1) 2
fx: lun# = (0)
...opening dksc(1,2,0)
...drive selftest...OK
Scsi drive type == COMPAQ  BD30088279      HPB4

fx/exercise/sequential: modifier = (rd-only)
fx/exercise/sequential: starting block# = (0)
fx/exercise/sequential: nblocks = (585937500)
fx/exercise/sequential: nscans = (1)
sequential pass 1: scanning [0, 585937500] (585937500 blocks)
0%

... and then you wait a long time until it reached 100 %


The rd-only test is sufficient as a basic confidence test. The wr-only test will erase the device. I often do that with 'new' (to me) disks. Any other option will cause significant head movement and make everything much much slower.
