if you do this on ASM disks or gpfs disks you are wiping the header. The device will stay up til your next reboot and be beautiful and clean after the reboot so this is a terrible idea.
You do get an output from the commands I listed even with ASM devices and GPFS disks and even from completely unassigned open disks. It might be a cryptic unreadable output but it is an output. If you get nothing or a one-line-error the disks are not open.
But maybe I have a different understanding what open means. Are you trying to find out if the disks are unused? Are you using AIX mpio or any kind of multipathing software? With ASM, before you make ANY changes to the disks, ask the DBAs to backup the disk headers. Strictly speaking by design, AIX has no idea if the disks are used or not - but oracle will hold a lock on them while still allocated - which is a curse and a blessing for above reason - you will STILL wipe the header. For gpfs, the cluster itself should be able to tell you which disks it is using - try
command. For normal disks in VGs, a simple
will tell you which disks are not in use from LVM perspective.

reboot
reboot(8) System Manager's Manual reboot(8)NAME
reboot - Restarts the machine
SYNOPSIS
/usr/sbin/reboot [-dlnq]
DESCRIPTION
When the system is running and multiple users are logged in, use the shutdown -r command to perform a reboot operation. If no users are
logged in, use the reboot command.
The reboot command normally stops all running processes, syncs the disks, logs the reboot, and writes a shutdown entry in the login
accounting file, /var/adm/wtmp.
The reboot command uses the sync call to synchronize the disks, and to perform other shutdown activities such as resynchronizing the hard-
ware time-of-day clock. After these activities, the system reboots. By default, the system starts and the file systems are automatically
checked. If the start-up activities are successful, the system comes up in the default run-level.
You must have root privileges to use this command. Using the -n flag can result in file system damage.
FLAGS
Generates a crash dump of the system before halting it. Can be used with any of the other flags. Does not log the reboot using syslog
Does not sync the disks or log the reboot using syslog Performs a quick reboot without first shutting down running processes; does not log
the reboot using syslog
EXAMPLES
To enable the default reboot action, enter: reboot This command causes the system to stop all running processes, sync the disks, log the
shutdown, and perform other routine shutdown and reboot activities. To shut down the system without logging the reboot, enter: reboot -l
This command shuts down the system and performs all shutdown and reboot activities, except logging the shutdown. To reboot the system
abruptly, enter: reboot -q This command reboots the system abruptly without shutting down running processes.
FILES
Specifies the command path Specifies the login accounting file Specifies the path of the syslog daemon
