Basic DLT question - d350 / 4000s

[HP System Handle Owner]

I am trying to add a dlt400s to a d350.

I have stape and tape2 in the kernel, but when I connect the device and issue an ioscan -fnCtape, it is not reporting reported either CLAIMED or UNCLAIMED. I know that the device works as it has come from a K server. I have tried issuing an insf, but it does not see the device. The device is attached to the single ended port on the back. I have tried another dlt4000 unit and have the same issue. Both have scsi id's of 0

I have attached an ioscan -fn, and the /stand system file for reference. I don't really want to have to reboot if possible.

Cheers in advance

Russell

I think you've got a F/W device connected to a SE port. Check how they were connected on the K - I think you'll find that the port was F/W. They won't work on SE, you've got a SCSI conflict and that's why the devices aren't being recognised.

Hi Russell,
DLT4000 is not a single ended device, use this on a fastwide SCSI controller then you'll be able to see the device properly.

Chaps,

Thanks for your replies.

I'm not so sure that is is F/W though. The tape unit has 2 x 50 pin connectors on the back and it was connected to the Hp-PB SCSI (SE) card in the K box. (It does not have 68 pin connectors on it)

Bit more info, the model number of the unit is CTS 2210-HP. It is connected to (8)/16/5

Cheers

Yes, please check if it's HVD or not and DO NOT connect it to SE if it's HVD.
Your server has only one HVD adapter at 8/4, and looks like it's already overloaded with disks (I guess there's Jamaica box connected). I suggest to add one mode HVD adapter to connect the tape drive. If it's not possible... then connect it to this one (daisy chain with Jamaica), but remember: your root/swap/boot disks are on this bus!

[Eugeny Brychkov]

Ok, there's only one SE adapter
ext_bus 1 8/16/5 c720 CLAIMED INTERFACE Built-in SCSI
which already has device with SCSI Id=0 connected
tape 0 8/16/5.0.0 stape CLAIMED DEVICE HP C1533A
so please change DLT's SCSI Id to 1 (for example) first

Youve got to plug it into 8/16/5 (50 pin SE controller) and change the scsi id - scsi 0 is alread used for the DDS drive. Change it to anything except 0, 2 (CD) or 7 (scsi controller).

Thanks all, I was sure it wasn't F/W !!

Changing the scsi id to 1 made me able to see a line in ioscan, so i did an insf and now I can see it and backup to it using fbackup.

Many thanks to all for your help

Points assigned out !
