Shalom Sandeep,

For proper tape drive functionality a driver called stape must be compiled into the kernel

sam
Kernel Configuration
Drivers
Make sure stape is in.

You will be prompted to recompile the kernel and boot the system.

After this assuming there is no SCSI device conflict, you should see the tape drivers and be able to use the tape device.

Hi,

what have you tried till now?
For creating the dev file use:
'insf -C tape'

Hi Sandeep,

If the stape drive is not set to static, set it to static in the kernel using sam or else use command "kcmodule stape=static". Please note that you would require a reboot after this. But if the drive is showing in ioscan, that means the driver is enabled & you probaby have a scsi id problem due to which the device file is not created.
Paste the "ioscan -fnC tape" output here. Also, try changing the SCSI id behind the drive. Note that you will have to remove power to the drive before changing the SCSI ID & then power it on again. It would be better if you remove the scsi cable as well before changing the SCSI ID.

Regards,
Vihang.

Please post the result of

# model
# ioscan -fn

To include the stape driver run

# # kcmodule stape=static

that cannot be applied immediately and which will be held for

Give the output of below command

ioscan -fnC tape

Check stape module to be set as static ( You can use SAM-Kernal configuration)

Do

insf -eC tape
ioscan -fnC tape

Thanks
