module loading

[Fred Ruffet]

I have an IBM LTO driver. Problem is that, at boot time, stape is affected to this LTO device instead of atdd IBM driver.

atdd module is loaded, but I'm looking for a way to affect atdd to this device.

I tried unloading and loading the module back, without success.

any ideas ?

Fred,
Ddi you isntall the pre-rquisiste pathces ?
Did you do the configuration in /etc/rc.config.d/atdd.cfg ?
There is a section on how to troubleshoot this in the ATdd driver manual from IBM ..
Here is the steps for your exact problem,

Run # lsdev to check that the atdd is in the current kernel: 1. If the atdd isnâ t in the output, rebuild the kernel or reinstall atdd;
2. If the atdd is in the output
a. rebuild the system I/O configuration:
1) Remove /stand/ioconfig and /etc/ioconfig after to backup the files;
2) Reboot the system;
3) On System Console, enter # /sbin/ioinit -c while the autobooting is halted;
4) Run # /sbin/insf -e
5) Enter # ^D to exit the I/O configuration
b. Consider reinstalling the HP-UX operating system if the system is new or this is a new update.

I solved it :)

Here is the problem :
atdd module from IBM starts with a script in /sbin/init.d, referencing a config file wich is NOT in /etc/rc.config.d as every start script should do, but in /var/tmp (!).

Someone shot the file, and as script sources the file, it exits.

I saw in the file the way to manually affect the module to the HW path (atdd_claim), and it now runs perfectly.

I put the config file in /etc/rc.config.d to be sure the next time... :)

Thanks,

Fred

That's strange indeed.. a config file in /var/tmp ..!!!!

That is just strange...
You may try modifying a the ibm script in /sbin/init.d to look for a config file in /etc/rc.config.d/ directory.

May admins clear up /tmp peridically, and you may run into the problem again.

Preapare the backup of the file, before you start wokring on it.

RAC,

That's what I did. Config file is now at the right place (/etc/rc.config.d) for the 5 servers I run this module on.

All I can do is to suggest every one running this driver (LTO driver for TSM) to do the same.

Regards,

Fred
