Failure adding 3rd hard drive

[Carlitos71]

I am adding a third SCSI drive to a Dell PE 1600SC on SCO 5.0.7 and I am running into a problem. After running the second invocation of mkdev hd I am getting this error...

/etc/fdisk: cannot open /dev/rdsk/2s0 for reading: No such device or address (error 6)
/etc/fdisk failed.

The system has two existing 36gb hard drives and the third is a 72gb. I am using "mkdev hd 2 SCSI-0 0 lsil 0" to add the hard drive. There is no 2s0 in /dev/rdsk, but if I remember correctly, I did not have to add the 1s0 for the 2nd hard drive that was added about 1 1/2 years ago.

Any help is appreciated. Thanks.

Carl.

Why have you said to the mkdev script that you had another lsil adapter ?

Hope This Helps, PH.

I did not think that was what I was doing. I could not find my notes from last time, so I went with what was in mkdev hd -u. From what I understood, that was just giving the Host Adapter type of the drive.

Well, I removed the 3rd drive out of the system using TA #105052 and then ran just "mkdev hd" by itself. But, I am still getting the same error as above. The drive is spining when it tries to run fdisk, but that is as far as it will go. Do you have any other ideas on what I may possibly doing wrong? Thanks.

Is the drive installed onto the same SCSI adapter and channel as the existing drives? You can run "mkdev .scsi" to display the existing values for your 2 drives. Sometimes that helps answer the questions presented in the "mkdev hd" script. Do not perform any other actions on the "mkdev .scsi" menu. Just display the info and exit.

Are you certain that the third drive is being seen by the adapter? Does it appear during the boot process? If there is a tape drive on that same channel, it might be sitting at SCSI ID=2. What SCSI ID did you set for this new drive?

 

[Carlitos71]

Motoslide,
sorry, I was sidetracked most of yesterday.

The drive is on the same adapter. But, I realized that I had put the drive on the same ID as the tape drive. Make sense now that I didn't get a good backup....d'oh.

I am going to remove the drive out, but I am wondering if I am going to have to do a mkdev tape since the tape drive is not working now. Any thoughts? Thanks.

I suspect the tape drive will be fine once the disk is removed from that channel. You will need to run through the "mkdev hd" process again, using SCSI ID=3 (or whatever).

Good luck!

Damn, damn, damn....
The third drive has been added, but it is only showing as a 4gb partition in divvy.
On bootup, it does show the entire 72gb
The drive is a Seagate Cheetah ST373307 and I am not sure if a geometry statement is needed or what. If so, how do you stipulate it as a drive on ID 3? Thanks for all of the help.

You may have to change the Int13 option in the SCSI adapter BIOS.

Hope This Helps, PH.

You get to pick the partition layout before you get to divvy (in the fdisk routine). On that screen, all you are presented with are cylinder values. What values did you select? There isn't a 4GB limitation in 5.0.7, so you should have been able to utilized the entire disk.
You stated that you already are using 36GB drives on the same adapter, so I wouldn't expect an adapter setting to give you grief. There's an O/S patch which improves performance on large filesystems. You will want that patch.

Moto,
I did not change anything from the default value, which I noticed afterward was only 4gb. I am planning on using the whole drive and not partition it.

I uninstalled it again and got the same size.

PHV, I changed the Int13 option but that did not help either.

I was going to try to manually set the cylinders, heads, and sectors with dkinit but it said the disk was not present.

Any other help would be appreciated.
