Orienting on an unfamiliar AIX LPAR before you type anything else
AIX 7.2/7.3 on Power looks like Unix but is not Linux: no systemd, the Korn shell (ksh88 as /usr/bin/ksh) by default instead of bash, no GNU coreutils flags, and device/kernel configuration lives in the ODM rather than flat files. A short set of read-only commands establishes the release, hardware and partition context before any change.

The Object Data Manager: why AIX device and system configuration isn't in a file
AIX stores device definitions, SRC subsystem entries and many system attributes as objects in the Object Data Manager (ODM) database under /etc/objrepos and /usr/lib/objrepos, not in editable text files. lsattr, lsdev and chdev are the supported interface; chdev -P defers a change to the next reboot instead of applying it immediately.
