As Jeff Schaller mentions - the cause is probably a missing fileset.
To answer your question - the error message is occurring because
lsdev is trying - and failing to find anything - with something similar to:
odmget -q uniquetype="adapter/pseudo/pkcs11" PdDv
If you can get to installp sources I would expect the fileset
security.acf - as I see 23
odmadd stanzas in that fileset:
root@x062:[/export/lpp/7103/installp/ppc/xx/usr/lpp/security.acf]grep -c "adapter/pseudo/pkcs11" * | grep -v :0
And, if I wanted to install security.pkcs11 I would have to search further - my
installp sources only contain an update. (The
:S: (2nd and 3rd lines) indicates only an update, while
:I: (1st line) indicates a base install
root@x062:[/export/lpp/7103/installp/ppc]installp -d . -L | grep "security\."
