Configure Tape drive on SCO

[Jason Groves]

Hi Bob.
 
Don't know if this helps but on a clients machine running sco openserver
5.0.7 there is no /dev/rmt directory. As far as I know thats a Unixware
directory but they might have added the same functionlity on Openserver 6.
One of my clients Unixware 7.1.3 directories show as follows: the device
major and minor numbers for ctape1 are 283,49.(see below)
 
BRPS-Dev:root:[/dev/rmt] # l
total 0
crw-rw-rw-    1 root     sys      283, 45 May 15  2006 c0s0
crw-rw-rw-    1 root     sys      283, 46 May 15  2006 c0s0n
crw-rw-rw-    1 root     sys      283, 48 May 15  2006 c0s0nr
crw-rw-rw-    1 root     sys      283, 47 May 15  2006 c0s0r
crw-rw-rw-    2 root     sys      283, 45 Jul 22  2007 c1b0t6l0
crw-rw-rw-    2 root     sys      283, 46 May 15  2006 c1b0t6l0n
crw-rw-rw-    2 root     sys      283, 48 May 15  2006 c1b0t6l0nr
crw-rw-rw-    2 root     sys      283, 47 May 15  2006 c1b0t6l0r
crw-rw-rw-    2 root     sys      283, 49 May 15  2006 c1b0t6l0u
crw-rw-rw-    2 root     sys      283, 45 Jul 22  2007 ctape1
crw-rw-rw-    2 root     sys      283, 48 May 15  2006 nrtape1
crw-rw-rw-    2 root     sys      283, 46 May 15  2006 ntape1
crw-rw-rw-    2 root     sys      283, 47 May 15  2006 rtape1
crw-rw-rw-    2 root     sys      283, 49 May 15  2006 utape1
 

The thing is, usually the system installs the devices needed on an
openserver based system, once you run the #mkdev tape command. the
definitions for the different devices are as follows:
ctape1        Non-retensioning rewinding device
ntape1        Non-retensioning non-rewinding device
rtape1         Retensioning and rewinding device   
nrtape1       Retensioning non-rewinding device   
utape1        Unloads on the device close.



Using an openserver based system, you usually have to add the tape device
but on a unixware based system(which it looks like openserver 6 has its
roots. as long as the scsi card is installed ,the tape drive is added
automatically. Put a tape in try using the /dev/rStp0 device, which is the
default device in openserver. so change /etc/default/tar. look for acrhive 8
which is your default tape device to /dev/rStp0. or use # find /etc/hosts |
cpio -vocB -O /dev/rStp0   (or one of the other /dev/rmt"devices" to test)



Hope you come right
Jason

Subject: Configure Tape drive on SCO



I have a DELL Poweredge successfully running SCO 6.  However I am trying to
get the tape drive working.

 

When I do a 'mkdev tape' I get the following:

Mass storage devices are configured automatically

when the system is booted with a new device present.

 

Current tape drive configuration:

 

Alias    - Address  - Inquiry String

--------   --------   --------------

hba6     - c3b0t7   - (adpu320,1) Adaptec Ultra320

ctape1   - c3b0t6l0 - SEAGATE DAT    DAT72-052A16E

 

See st01(7) for information about tape drive device nodes.

 

That's fine however when I look in /dev/rmt I only have:

 

c0s0        c0s0r       c3b0t6l0nr  ctape0      rtape0

c0s0n       c3b0t6l0    c3b0t6l0r   nrtape0     utape0

c0s0nr      c3b0t6l0n   c3b0t6l0u   ntape0

 

So ctape1 does not exist.  I'm not exactly sure why SCO choose ctape1 since
this is the only tape on the system.

 

How do I go about creating the nodes for ctape1?  Do I have to do it
manually(mknod)? If so what are the magic numbers?

 

Any attempt to access any of the existing device nodes results in errors:

 

# tape status /dev/rmt/ctape0

tape: can't open '/dev/rmt/ctape0': I/O error

 

Any help would be appreciated.

 

Thanks

Bob
