Hi all, I am trying to purchase a server from DELL Computers. I need about
500gb Raid capacity. Dell thinks I should not purchase this server. I need
large drives and I cannot get enough of them in a 6 bay drive enclosure.
So I was trying to buy there add on drive enclosure.following is the
internal correspondences. Seems there may be a SCSI problem using an
external card cage with there controller. Is there anyone who could
enlighten me on this, as I really need the server... I do not know the date
of this correspondence so Im hoping this has been fixed. thanks in advance
all....
Q:
I am getting a validator error with the
PE4400 with a "Drive Cage" and Linux no matter
if I am using a second channel on the raid
controller or scsi on the cage. Is there an issue
with Linux or Dell mfg or is this bogus?
A:
The error is due to a
restriction placed against Linux and the Cage. The way the Linux OS
initializes, it does not recognize the multimedia bay
drives. I do not have an updated
status on this but as I recall, it was contigent on the next release of
Linux. I am calling my development contact
now and will update ASAP.
--------------------------------------------------
Q:
Does this also mean that Linux will
not recognize external storage like the PV200s on a seperate raid/scsi
channel or is it just the media cage?
A:
I just spoke to the development engineer and
found out that there is a 50/50 chance that the media bay will be
recognizable by Linux in the next release which is scheduled for the August
/ September time frame. Red Hat owns this corrective action and is working
it. As far as the external storage, it wll work fine. The issue is with the
embedded controller being "split" and Linux can not hack it. A separate
controller works fine.
---------------------------------------------------
Q:
If I am understanding this correctly.
The restriction is due to the controller being split. In this paticular
The backplane is connected to an add-in Perc3/DC and the cage is connected
to scsi controllers. Shouldn't that work if the cage is connected to dual
scsi or a single scsi port?
A:

The way the mother boards are configured
with the embedded controllers, Linux errors and will not recover. It is all
quite confusing but it is an unfortunate fact that we will have to
deal with until it is resolved by Red Hat and the Linux OS. The fact that
you have add on controllers really will not make any difference as it is an
issue
during initialization of the OS.
