Tape Drives show as unknown

MikeL_4 — Thu, 07 Oct 2004 08:14:59 GMT

I have an 11.23 server that they attached two tape drives to:
- HP dds3 4mm that can go to 24gb with compression
- Exabyte 85xx 8mm that can go to 12gb with compression

Both are seen with the ioscan but show as unknown:
target 7 0/1/1/1.5 tgt CLAIMED DEVICE
unknown -1 0/1/1/1.5.0 UNCLAIMED UNKNOWN EXABYTE EXB-85
05SMBANSH2
target 5 0/1/1/1.6 tgt CLAIMED DEVICE
unknown -1 0/1/1/1.6.0 UNCLAIMED UNKNOWN HP C1537A

Is there drivers I have to download for these drives and install, and if so where can I find them ??

Thanks

You need to add the tape drivers to the kernel. This is done most easily via SAM.

Invoke SAM, then go to Kernel Configuration and then Drivers. Scroll through the driver list and select 'tape', 'tape2' and 'stape' drivers. The go up to the Actions menu and select 'Add Drivers to Kernel'. When that is done go back to the Actions menu and select 'Process New Kernel'.

This will regen the kernel and force a reboot of the machine. When the machine comes back up, you should see your tape drives and be able to use them.

Mike,

You need to configure the stape driver into your kernel. It's probably easiest to do this with SAM > Kernel Configuration > Drivers.

Mike,

It is tape2 driver in your kernel or 'out'? This is the driver for dds tape drives.

I am not sure about the 8mm drive... It could be the 'stape' driver.

Do a 'grep tape2 /stand/system' and 'grep stape /stand/system' to see.

Hi,

you'll need the "stape" driver here

look if it's there using "kmsystem"

if not then use

kmsystem -c y stape

to configure it into the kernel

Hi,

because this is 11.23 OS there is no kmsystem
command. You can check you driver module
by command kcmodule

kcmodule | grep stape

and you can try:

kcmodule stape=static - it will rebuild kernel

or use kcweb interface
