disk instalation

[Vogra]

Hi All!
I need to install a more one disk on D270/2 HP9000.
I have one disk running (disk 1). The second disk (disk 2)is same of the first (barracuda-seagate - st32550n). Disk 1 is P/N HP, disk 2 is P/N Compaq.
When I install both, the server don't recognize the new disk.
The only difference that I saw is:
on back of the disks are pins like this:
--first-------------second----
::::||:::| ---- ::::::::::
------------------------------
on disk 1 the pins 5,6 and 10 are jumped; on disk 2 neither.
The question is: it's possible configure disk 2 to run ?
thanx in advance.
Lima.

This could be a SCSI ID issue. If you check the label on top of the disk, the SCSI ID pattern will be written there.

Set both disk on different SCSI IDs, then it will start working. Make sure that the IDs you are setting is not clashing with any other devices on the same BUS (like tape drives).

Find out the SCSI IDs already set through ioscan. Then set the SCSI ID of the disk. It has to be unique in that SCSI chain. Look around the disk abt how to set the SCSI ID.

I suspect that you have a SCSI conflict. The 2nd disk is set to 0; that is the normal SCSI ID setting of the DAT drive on a D-box. Typically, the 2nd drive is set to '5' - jumpers 4 & 6 but you should first do an ioscan -fn with the 2nd drive removed.

OK ..here you go:

Check this document:

http://www.seagate.com/support/disc/scsi/st32550n.html

If you are talking about the "J4" jumpers, then the disk-1 is set for SCSI ID - 6.

Set the second disk as 5, that is 4th and 6th jumpers. Right now the second disk is not set any jumpers, that means it's ID is- 0. This might be clashing with a tape drive (usually ID -0)

Hi,

Your new disk is having a SCSI disk ID 0.

You may already have a tape drive installed on ID 0 and hence it may not get recognized.

Pls set the SCSI IDs properly and try.

When you boot the server, stop the booting sequence and then

execute sea ( search for devices )

There you can check the ID of your current disk and the new disk also. If the disk is getting sensed by sea command then only your OS will recognize ).

Hi Claudio


Try this setting:

1. Leave the first disk as it is.
2. Install a Jumper on the 3rd Pin
::::||:::| ---- :::::::|::

This will set the jumper of the comapq disk to id 4 which should not clash

Hi all!
I changed the scsi id to 5 (it's a long history...)
it was a 4th disk on flat cable.
The "bexiguento" it's ok now.

Thanx so much to all,
Lima.
