Installation of a new 18GB HDD in my Compaq Proliant ML350server

[Bosa Henry]

I have a Compaq Proliant ML 350 server with two mirrored 9.1 GB HDD's. I wish to install an additional 18GB scsi HDD but I am having problems. When I mount the new HDD the machine will not boot. I have tried to use the profile Floppy and the smartcd but they have all failed. Can anyone help?

NB. I do not want to lose the data on the smaller HDD's because I want to install windows 2003 server software on the new HDD using the user info. on the old HDD's.

Hi,

Since the server is working with OS as preconfigured. What we need to do is touse ACU (Array configuration utility ) Install the Hdd and start the server under OS then under Windows We can configure our driver under RAID.

We can use ACU to add a new Array and assign it as radi 0 and use the HDD since we have one 18 GB hdd only.

Information regardgin the ACU is avaible at following link

Hi Peshant,

Please note that the moment I install the new 18GB HDD even with the old HDD's present, the machine will not boot i.e I cannot access windows.

Bosa, are these drives hot plug or non hot plug drives? and are they connected to an array controller or to the SCSI controller?

[Bosa Henry]

Vijay, they are hot pluggable and it has a scsi controller.

[Vijay_44]

So you are using SW raid. Did you ID the new drive? When the server posts do you see unique ID's for the 3 drives. Try setting the id of the new drive to be higher that the two existing drives.

[Vijay_44]

....actually since these drives are hot plug drives. the slot position in the drive cage determines the scsi id of the drive

[Bosa Henry]

Vijay, I will try this and confirm tomorrow thanx.

Bosa,

It may be failing or hanging due to installing the new disk at a lower SCSI ID thn the other disks in the hot-plug bays.

The SCSI controller may see the new drive as the first hard disk when it scans the SCSI bus and try to boot from it. If you install it at a higher SCSI ID then the original disks will be seen first and things should be OK.

Please see the attached diagram which shows that the SCSI ID's on the hot-plug bays begin at 0 from the bottom - example is ML350G2 tower model.

I hope this helps.

Hi guys,

I now have tried Vijay's suggestion but without success. Before I install the new drive, the server posts ID0 and ID2 as the scsi ID's for the old 9.1GB drives. When i install the new 18GB HDD the server posts "ID0 failed" but continues to detect ID2. Moreover, I install the new drive on the connector furthest from the scsi cable lock.

Thanx Brian for the diagram but my HDD mountings are vertical not horizontal.
