Stopping/starting NFS (stopsrc -g nfs/startsrc -g nfs) to make new or modified shares known to the outside world or to remove shares is not appropriate, or better, it does nothing in regard to exporting/unexporting shares.

You'll have to run "exportfs", be it with the "-a" flag (re-export, or export if new, everything listed in /etc/exports) or
"exportfs /path/to/share" (re-export, or export if new, the named share) or with  "-u /path/to/share" (unexport the named share). "exportfs -u -a" will unexport everything listed in /etc/exports (!!)

During reboot the NFS startup script "/etc/rc.nfs" will not only start the NFS services but will also perform "exportfs".

Please be careful when running on AIX 5300-12-04-1119. regarding NFS this Version/TL/SP combo will every now and then not fully behave as expected!

Unix is a multitasking, multi-user computer operating system originally developed in 1969 at Bell Labs. Today, it is a modern OS with many commercial flavors and licensees, including FreeBSD, Hewlett-Packard’s UX, IBM AIX and Apple Mac OS-X. Apart from its command-line interface, most UNIX variations support the standardized X Window System for GUIs, with the exception of the Mac OS, which uses a proprietary system.

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.

Linux is a UNIX-like open source operating system with hundreds of distinct distributions, including: Fedora, openSUSE, Ubuntu, Debian, Slackware, Gentoo, CentOS, and Arch Linux. Linux is generally associated with web and database servers, but has become popular in many niche industries and applications.

Linux

Operating systems perform basic tasks, such as recognizing input from the keyboard, sending output to the display screen, keeping track of files and directories on the disk, and controlling peripheral devices such as disk drives and printers. For large systems, the operating system makes sure that different programs and users running at the same time do not interfere with each other. The operating system is also responsible for security, ensuring that unauthorized users do not access the system. Operating systems provide a software platform on top of which other programs, called application programs, can run.
