Danny,
Aplogies for the lack of information.
Obviously you did not check our resident fool out.
You were right in your assumptions -
Right, obviously the information was there all along if you 'know' your RAIDs.
It is a RAID 1 (mirrored) array,
running 2 80 GB SATA Hard drives. The drives are identical.
AFAIK it is a LSI Logic Raid chip - It's a Fujitsu Siemens Econel 40 Server.
It is certainly an LSI Logic Bios that you go into to configure the RAID.
I did a "rebuild" from the BIOS menu.
Took a good few hours,
That sounds like there is either a problem or that it is using a very slow
method of copying and verifying. Since it won't boot, probably the former.
and then seemed to complete, but did not boot correctly. When you
remove the new drive from the array, then the server boots fine.
Yup, that's what you said earlier.
I am assuming that the array is not properly rebuilding and the data is not
being correctly copied onto the new drive, but it really is an assumption.
It does appear so.
It also suggests that the controller distributes the reads between the drives.
Let me know your thoughts,
Oh no, you don't want his thoughts, trust us.
He can't even setup his newsclient properly.

I'm sorry, you're just not giving enough basic information.
What kind of array is this?
What kind of chip is running it?
You see, what doesn't make sense, is you saying the array isn't
rebuilding properly, but the new disk booted up fine. This leads me
to believe this is a 2 disk RAID 1 array?
Are you saying it didn't RAID all the way? Then why would it boot?
I don't know, I'm confused;
exactly what isn't working?
Maybe you just need to create an array from the one you just built?
Andrew Seatonwrote:Hi All,
I would love a bit of advice on a server that I am looking after.
2 Weeks ago, I noticed that it was slowing down, and after a reboot it
showed that the "raid aray degraded". One of the SATA disks had failed. No
problem, I thought - I'll get an exact copy and rebuild the array.
I got the exact same drive - (exact model number) and replaced it. I then
went into the LSI Raid BIOS and told it to "rebuild" the array. After a good
3-4 hours, all seemed ok. The array showed "online" on both drives. However,
when I rebooted the array it only got to the pre-windows screen and
complained about not being able to find a number of files, and wanted me to
insert my windows 2003 cd to rebuild the server.
I then powered down, unplugged the "new" drive onto which the array should
have rebuild and the server booted fine off the one disk. The server has
been running OK for a week on this one drive *(not ideal, but no choice
really)*. I have looked around for advice but to no avial.
My real question is what am I doing wrong? The manuals are fairly sketchy,
and I really would like some advice on this one, as RAID isn't my strong
point.
I am guessing that for some reason the array isn't rebuilding properly - but
beyond that I am stuck.
Many thanks in advance for your advice,
Regards,
Andrew.
