<div>Not sure if this is anything. BUT, is the 0-4 pair the 1st pair in the list? Is it possible that that pair is some how a master, or control pair for the other arrays? ... You might want to see if the array mapping is mirrored on any other pair besides the 0-4 pair, that could be a setting somewhere.</div> <div> </div> <div>I've had old hardware (DEC Alpha) that would not boot off a raid 5 on the initial drives - you could mirror them but nothing past that. If you took the total set of drives and created a single raid 5 the unix/linuz varient would not recognize it (windows liked it though) - I ended up creating two arrays, the OS boot disks ended up living out side the data array for monitoring and configuration. Not the most efficient usage of the disk drive space. This was the dark ages though and more modern hardware might be better at working around this issue.</div> <div> </div> <div>Joe

Whenever I pull a drive from the 1-5, 2-6, and<BR><BR>3-7 pairs and then reseat the drive again, that particular array <BR>rebuilds itself quite nicely. However, BOTH drives in the 0-4 pair <BR>(which is my OS array on these particular servers), go red (ie the red <BR>error lights come on). My question is is that I am not understanding <BR>why a drive pulled in one array should affect the drive(s) in another <BR>totally different array.<BR><BR>Any ideas anyone can give me at this point would be greatfully <BR>appreciated as Adaptec technical support is pretty much useless at this<BR><BR>point. Hopefully I didn't give too much detail here :)<BR><BR>TIA!<BR><BR>--<BR>Robert Wolfe<BR>Systems Administrator<BR>LocalNet Corp.<BR>CoreComm Internet Services<BR>(517) 664-8924<BR><BR>_______________________________________________<BR>nflug mailing
