[nflug] Adaptec 2230S RAID Woes

[Richard Hubbard]

This is a complete swag, but it sounds like the pair 0-4 is messed up, either one of the drives is bad (but that should show up as a red/orange light), or there might be a glitch on the controller itself.

What your describing on the pairs that aren't 0-4 is exactly how it should work.  Is it still under warranty?  Any possibility of getting it fixed/replaced?

Of course, I could be a little snarky and recommend the EXPRESSPCI UL5D DUAL-CHANNEL, ULTRA320, PCIe  SCSI HOST ADAPTER  from ATTO, (http://www.cdw.com/shop/search/results.aspx?key=+EPCI-UL5D-0R0&platform=All&sr=1&Find+it.x=44&Find+it.y=14  $516 from CDW ) with better tech support, and a second external scsi port, and 2 internal ports..

Ok, to begin with, let me begin by giving a little background.

System:
 http://www.supermicro.com/products/system/2U/6025/SYS-6025B-8R+V.cfm
Motherboard:  
http://www.supermicro.com/products/motherboard/Xeon1333/5000V/X7DVA-E.cfm
SCSI Controller:  
http://www.adaptec.com/en-US/products/scsi/ultra320_pcix/ASR-2230S/index.htm

These servers have 8 73GB SCSI drives in them, numbered 0 to 7 in the 
following order in the servers:

     4 5 6 7
     0 1 2 3

All drives are hot-swappable.

The OS on these servers is Debian 4.0r1 'Etch'.

Motherboard and controller BIOSes have been flashed to the latest rev
 level.

There are 4 RAID arrays with drives paired off in the following manner 
(reference to 'diagram' above):

0-4, 1-5, 2-6, 3-7

Now here is my dilemma.  Whenever I pull a drive from the 1-5, 2-6, and
 
3-7 pairs and then reseat the drive again, that particular array 
rebuilds itself quite nicely.  However, BOTH drives in the 0-4 pair 
(which is my OS array on these particular servers), go red (ie the red 
error lights come on).  My question is is that I am not understanding 
why a drive pulled in one array should affect the drive(s) in another 
totally different array.

Any ideas anyone can give me at this point would be greatfully 
appreciated as Adaptec technical support is pretty much useless at this
 
point.  Hopefully I didn't give too much detail here :)

TIA!
