A disk read error has occurred when booting a Dell PowerEdge 2950. Passes all diagnostics. Will run chkdsk from CD. Raid battery was degraded at last reboot but all disks showed to be fine. Raid 1
no raid card stated, no array stated, no type of array stated.
One can put 100s of RAID cards in this server.
both raid cards or HBA cards,(forJBOD)
i can fix any server, but first need to know what is in the box first
you meant the boot disk has errors, right,? boot.
that would tell me the disk IS BAD.
but if and ARRAY , that means you must run SMART tests
on the disks, 1 by 1 to find the bad disk.
if smart shows its bad, or weak its for sure BAD.
on real servers. the server sends you email, (set up right)
telling you disk 3 in a RAID 6 is bad, replace it now.
are you running hardware or software raid, or HBA or
fake raid cards, (4 classes there.!)
the base system new has.
4 port SAS 5/i integrated SAS controller (no RAID_
and optional, from DELL , news.
Optional PERC 5/i integrated SAS/SATA daughtercard controller with 256MB cache,
PERC 4e/DC, PERC 5/e adapter
or any of 1000s of other aftermarket cards there.
I run LSI 9361s (with MSM appl loaded)
this card will tell you what disk failed every time no kidding.
so will the PERCs setup correctly
the PERCs and my LSI and my HP raids
all have installed monitors for the RAID ,a program that runs full time all the time, and reports errors , many ways,
did you load that first and use it? seems not.
as no mention of SMART at all.
Im not sure the names on DELL , MSM like software.
ah its OSA
never run a PERC lacking this APP. or you can not keep the server on line,.
