I have 4 hard drives, 3 are member of Adaptec 131U2 Raid 5 and 1 is the spare.
=================
A while ago, ID1 & ID3 were down, ID2 is OK.
In fact, ID1 motor stopped and NOW it comes back. How do I force the ID1 down status back online? I should reconstruct the Raid from ID1 and ID2.
=======================
By the way, all the command CI/O is gray and I can reconstruct hard drive and reactivate the offline array.
============================
Is there one unversal Raid utility for all the different Raid controller card?
--------------------
Are any more flexible and better Raid card to allow me to force to turn down hard drive to up, force to turn offline array to online manually as I know ID1 is OK physically?

--------------
Thanks

From my experience, if you are having problems with more than 1 drive in a RAID 5 configuration, you will probably not be able to rebuild. If your RAID software doesn't let you put an array online it might be because of a hardware issue. Sorry I can't help you here much.

In fact, ID1 motor stopped for a while and NOW it comes back as normal. How do I force the ID1 down status back online?
====================
I know that IBM Raid Configuration disk can force the Array online. But Adaptec one does not or I do not know how.
=====================
I should reconstruct the Raid from ID1 and ID2 as they are OK physically.
