Creating the Device Files Using the mknod Utility
An important final step in the autochanger installation is creating the device files
required to use the autochanger. Again, you need the SCSI addresses previously
selected for the autochanger.
To create the device files to bind the LDEV numbers to the POSIX device special files,
follow these steps:
1. Create the robotics/”picker” device file as follows:
> mknod/dev/sjid1u1 c 0 30
2. Create the tape device files as follows:
>
mknod /dev/tape31 c 0 31
>
mknod /dev/tape32 c 0 32
>
mknod /dev/tape33 c 0 33
>
mknod /dev/tape34 c 0 34
Where 30, 31, 32, 33, and 34 are the LDEV numbers you assigned in sysgen.
Configuring Tape Devices to Accept Data
To configure tape devices to accept data, use one of the following procedures:
• At the MPE prompt, enter the following command for each tape device:
:
accept data
ldev number
For example:
>
accept data 31
>
accept data 32
>
accept data 33
>
accept data 34
• Place the accept data command in the MPE startup file SYSSTART.PUB.SYS.
• Place the accept data command in the NetWorker startup file
JNSRSTRT. NETWRKR.SYS.
Note: The accept command is executable only from the console, unless distributed to
users with the allow command.
