Exactly. AIX stores information about devices generally in the ODM. Since this is updated only by a run of cfgmgr (in fact that is the very purpose of this command) it might be that a device is still defined in the ODM (because once it was available but is not any more now) describes a device that is already removed (or not working for some other reason). These devices will be in state "Defined". Re-plung them in and they become "Available" automatically. Delete them from the ODM (via rmdev and they will be gone forever - only to return after being replugged and cfgmgr is run again.

You need to use a driver that works (duh! ;-)) ). It does not only depend on a disk if a driver works or not but also on the nature of the connection LUN<->host system, the storage subsystem involved the type of fabric you use and so on.

I hope this helps.

DESCRIPTION
mic-livecd-iso-to-disk can convert a livecd image to a live USB image and write it to a USB disk or partition, it is different from mic- image-writer which is just a safer dd with progress bar. mic-livecd-iso-to-disk can detect all the removable USB disks and let you select one of them, if you didn't insert any USB disk, it will ask you to insert until a USB disk is available, it can decide if your USB disk need to be formated and if your USB disk has an appropriate partition for this livecd image, all the operations are interactive and have warnings f they will damage your old data on your USB disk. mic-image-manager has a GUI tool for it.
