I've recently had a Dell PowerEdge 6300/550 fall into my lap.

It's an older server with four P3 550 Xeon CPUs, double redundant power supplies, 2G RAM and a six SCSI drive RAID 5 array and it works just fine. It has Windows Server 2000, (3?) installed and working in the sluggish, awkward manner that all Windows setups work... or don't... 8\

However, eCS 1.2r installation CD 1 does not acknowlegde that the drive(s) exist, though it does load drivers for the SCSI adapters, (not the controller though... but that's expected).

The manual, (and SCSI RAID sites), say that the RAID 5 container which holds the drives, is transparent to an OS and it/they should appear as one, big drive to the OS WITHOUT the need for any drivers.

I booted DFSee 8 from the CD and it recognizes the one _big_ drive as expected. Still, nothing I do can make eCS detect any drive(s) whatsoever.

I've scanned both Adaptec's, (who makes the controllers), and Dell's websites for a driver, (though, supposedly none is needed), and found nothing, but mis-linked references to OS/2 and this setup.

OS/2 eZine has a reference to a DELL 6650 system working under OS/2, but that's too dissimilar.

I've posted to the newsgroup ecomstation.support.hardware and were talking about it, but nothing concrete has come up.

I've sent two e-mails to the DFSee support group, but the messages haven't shown up... strange.

Has anyone here had any experience with this server? or with using a RAID 5 setup with OS/2 or eCS?

Ben, I do not have any experence with RAID, but have you tried to partition and format the drives with DFSEE,and then try to install ecs 1.2mr?

No. I haven't tried that one yet. If I wipe the drives without the ability to put an OS on it the machine becomes a huge paper weight... pretty much.

I would do it in a flash if I knew that it would work. Do you know, for sure, if that would change anything pertinant?

I mean eCS can't see any drives at all. It would seem logical, (though I'm no master of this), that find drives first, then find partitions.

Do you, (or anyone else), know if partitionings can affect the ability of eCS to see a RAID container?

Hi,

The RAID adapter on this system is likely to be a PERC 2 or a PERC 3 adapter (more likely PERC 2/SC).

Your best chance at getting it working is by using either the OS/2 I2O storage driver (I2ODASD.ADD?) or secondly by using the INT13 IBMINTI13.I13 driver.

Dell produced an OS/2 driver for the original PERC (1) adapter, but not for any others.

Regards,
Moby.

Greetings, Moby.

There is some reason to believe it's the Perc2 as some Perc2 related drivers, (windows), were left on the machine... though the previous owner has about a dozen servers so it could be for something else.

The only driver I could find with any mention of I2O is the;

Intelligent I/O Storage, i960 with IRTOS (I2OSOSM)

This does nothing 8( and the INT13 crashes out the machine.

Have you worked on these machines before?

Hi Ben, I have some experence with SCSI RAID. I went to the DELL site and it shows PERC2 RAID controllers made by both Adaptec and AMI . The AMIs appear to have drivers listed for them. The Adaptec PERC2 controller does not have an OS/2 driver listed.. I have an older PowerEdge RAID (AMI) that I had working with the MegaRaid driver, since the hardware was actually an AMI MegaRaid with BIOS that reported it was a PowerEdge. Maybe you can do the same thing with your Adaptec PERC2? Try using the Mylex RAID driver DAC960.ADD . With luck it will recognize your controller as a Mylex and allow eCS to install. Good luck.

Hi Ben, I was under the ( wrong ) impression that the Adaptec PERC2 was an i960 based controller. Don't bother trying the Mylex driver. Adaptec is using StrongARM processors on these controllers. So far I have not located an eCS driver that will work with this controller. I will keep looking. You may have to get a different RAID controller, if you want to run this server. Good luck

Greetings.

Yes, StrongArm controllers, that's them.

I haven't been able to find anything that works yet either, so it has become a paper weight. 8(

I do appreciate you checking for me though.
