Ultrium 230 on Redhat 7.3

Vinesh Dhevcharran — Tue, 21 Jan 2003 06:52:13 GMT

Hi,

New Linux user on board so expect a flood of stupid questions....

We have just got an IBM 255 server running Redhat 7.3. We have an HP Ultrium 230 also installed. We have don a default install of the OS.

The machine sees the Ultrium as per the /etc/sysconfig/hwconf. I have the following problems/questions:

1. What is the equivalent to ioscan -funC tape on Linux? (kudzu?)
2. Will the above command tell me the device name to use e.g. /dev/rmt/c0t4d0BEST ?
3. Is there anything that I would need to see this device from the OS (additional patches etc)?

Many thanks.
Vinesh

Hi !
kudzu is a hardware detector, which'll detect new hardware installed on your machine and ask for instructions if found.
From gui, you can use hardware browser which'll let you see your hardware.
Through this, you'll also see how it is referenced /dev/something).
lspci -v will also let you see PCI devices (if it is the case for your tape Which I do not know).
Hope it helps.

1) ioscan:
have a look at /proc/ file system, in particular the 'ioports', 'interrupts' files, as well as 'scsi/scsi' etc.

If you just want to look at SCSI devices, you can actually use 'cdrecord -scanbus'.

Otherwise, 'lspci', 'lsusb', 'lspnp' might help.

2) device names:
not really. If you look at the output of 'dmesg' (or /var/log/dmesg), you'll see the device names. For a tape however, it will be /dev/[n]st0.

3) other:
Assuming the kernel modules are installed (they are by default), as soon as a tape drive is detected, the 'st' module will be inserted (lsmod, look for a line starting with 'st').

Devices is accessable after this.

Hi,

The Linux device naming is described in /usr/src/linux-/Documentation/devices.txt.

Good luck.
