ioscan shows the tape and schgr devices. The tape drive functions, but the exchnager does not. Using the "mc' command, we "no device".
Is there a special set up for these libraries?
Solved! Go to Solution.

Re: MSL6030
The schgr has a device file like
/dev/rac/c8t0d0
mc command is
mc -p /dev/rac/c8t0d0 -r ISDM (to check inventory)
mc -p /dev/rac/c8t0d0 -s S1 -d D1 (to load a tape)
mc -p /dev/rac/c8t0d0 -s D1 -d S1 (to unload a tape)

Re: MSL6030
Have you rescanned everything yet?
ioscan -fn
insf -e
Is it still claimed then?
Double check also your scsi cables.

Re: MSL6030
Can you run this:
ioscan -fn > ioscan.output
and then post the output?
Have you created a device file for the robot with the mknod command that uses the sctl driver?

SolutionSince it may be hard to find, here's a summary on how to make the sctl device file:
The following command is used to create the device file for the sctl driver to the robotics:
mknod /dev/scsi/
where
The minor_# is of the format "0xIITL00" is determined by looking from the ioscan output. They are as follows:
II -> The Instance number of the SCSI bus interface (NOT of the device). This is reported by the ioscan -f output is in the second column, labeled with "I".
T -> The SCSI address of the library robotics.
L -> The LUN number of the library robotics.
00 -> Two hexadecimal zeroes.
Here is an example:
> ioscsan -fn | more
ext_bus 48 0/4/0/0.1.23.255.0 fcpdev CLAIMED INTERFACE FCP Device Interface
target 18 0/4/0/0.1.23.255.0.0 tgt CLAIMED DEVICE
autoch 2 0/4/0/0.1.23.255.0.0.0 schgr CLAIMED DEVICE HP MSL6000 Series
/dev/rac/c48t0d0
tape 43 0/4/0/0.1.23.255.0.0.1 stape CLAIMED DEVICE HP Ultrium 2-SCSI
tape 44 0/4/0/0.1.23.255.0.0.2 stape CLAIMED DEVICE HP Ultrium 2-SCSI
ctl 52 0/4/0/0.1.23.255.0.0.3 sctl CLAIMED DEVICE HP NS E1200-160
In the example, the instance number is 48, so we must enter 0x30 as hexadecimal digits, (i.e. 30). The SCSI address and Lun for MSL robot below are 0 and 0. (the last two digits of device path).
The command would tehrefore be:
> mknod /dev/scsi/MSL6000 -c 203 0x300000

Re: MSL6030
Your suggestion work 100%. Thanx - points awarded. Does ask the question as to why this is not configured automatically.

Re: MSL6030
For automatic detection, you create a device file in /dev/sctl instead of /dev/rac.(using mknod command)
It will automatically detect and configure robot as well as tape drive.
