Basically, you should also ask - went into Defined state from what.

FYI (although you may know this already) - Defined means, simply, that there is an entry in the CuDv (Customized Device) ODM file. Available means there is "also" a system driver/kernel extension that is associated with the device.

An Available device can be made Defined by using the command
rmdev -l devName
And made available using the command
mkdev -l devName

AND: this needs to all be happening via the ODM
Code:

root@x107:[/export/lpp/7102/installp/ppc]lsdev -C | grep et0       
et0        Stopped         IEEE 802.3 Ethernet Network Interface
inet0      Available       Internet Network Extension

In short, what I hope to point out - defined is a particular - and often NORMAL state for devices listed by lsdev. Especially if the device is being managed "manually" rather than via ODM (aka cfgmgr).

I hope this clarifies (helps) with understanding device states on AIX. Smilie
