Networker LUS Driver on AIX

Question

I was having device numbering and discovery issues on AIX 5.2, while running NW 7.5.2 I have 2 libraries available via FC to the AIX server. Only one is currently licensed for use with NW. When the primary library failed, I forgot about the secondary library and the library was discovered and moved into networker during a networker dev scan I removed all libraries from networker and also all tape / smc devices from AIX .. now I can only discover the tape devices and single smc from AIX. I am unable to see anything from the inquire command. I believe my error was performing an 'rmdev -dl fcs0 -R' to clean up the AIX devices. This appears to have removed some of the definittions necessary for the LUS driver to load and condigure the Legator library contoler. Any one know the process short of completely trying to Reject the Networker software and re-install? (Or is that valid to do - without lossing any of my media and index data?) Thanks

To my knowledge the LUS driver set is not part of the IBM Atape drivers.

The IBM Atape drivers add information for the IBM LTO and other tape drives, and the SMC driver which is used by other backup software to control the library robotics.

The LUS driver has to be part of the the Storage node Networker package set.

(Cfgmgr)

Hi I just put in the commands for changing the driver since I saw them in my AIX 'cheat sheet'.  I implied, but didn't mean to, that you needed to use those drivers.  Sorry! tl

Hi

I'm certainly not an AIX expert, but here are some commands that I jotted down, for the few times I've needed to test with AIX:

lsdev -Cc tape - shows tape devices found

cfgmgr - scans for hardware changes

Replace AIX Atape driver:
        rmdev -dl rmtX
        /usr/lpp/Atape/deinstl/lpp.deinstal
        installp -acXd /tmp/Atape....bin all
        cfgmgr

Hope some of this helps!

Actually as off as the anwer was it helped alot.

it drove me to /usr/lpp/LGTOnw.node/inst_root

which has the ODM objects to load and unload as well as the methods to configure the LUS device

I ran unodmadd and the odmadd info back followed by the config which brought the device defined and available
