    I have an Adaptec ASR-51245 RAID controller with 8 drives in a RAID-5 array.

    With the array in good condition, if I shut the system down and then restart, the last drive is most often not detected on power-up. Once the system is back up in degraded mode, I can force a "re-scan" to pick up the last drive and the array is then rebuilt over the next 8 hours or so.

    I have set the "spin-up" limit to 1 in the hope that this would prevent the problem, but it still persists.

    Does anyone have an ideas as to what might be wrong or can be done to resolve this?

    Thanks, David
