I support a bunch of 3575 tape lib's on AIX servers
and all of them always return an errno 46 when closing
a drive device with tapeutil. Usually this has no
relationship to readiness from a *SM point of view,
though.
Since it sounds like you are a veteran AIX'er, I guess
I don't have to tell you how to run diags against the
drives, now do I? I don't know what the L-06 models
support from the front panel, but I would definitely
try the equivalent of a "Configure Library" on an L-18.
I would also try to shut down *SM and attempt to write
and read from the devices in question using tar, cpio,
etc. just to make sure there are no driver/cfgmgr/ODM
issues. Removing the devices and running cfgmgr to
rediscover them might also be helpful.
Good luck!
