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.

scconf_quorum_dev_netapp_nas
scconf_quorum_dev_netapp_nas(1M) System Administration Commands scconf_quorum_dev_netapp_nas(1M)NAME
scconf_quorum_dev_netapp_nas - add and remove shared Network Appliance network-attached storage (NAS) quorum devices and change various NAS
cluster quorum configuration properties or states.
SYNOPSIS
scconf {-a|-c|-r} -q name=devicename otheroptions
DESCRIPTION
Note -
Beginning with the Sun Cluster 3.2 release, Sun Cluster software includes an object-oriented command set. Although Sun Cluster software
still supports the original command set, Sun Cluster procedural documentation uses only the object-oriented command set. For more infor-
mation about the object-oriented command set, see the Intro(1CL) man page.
A Network Appliance NAS device can be configured as a quorum device for Sun Cluster. The NAS configuration information consists of:
o a device name, which must be unique across quorum devices
o
a filer name, which defaults to the device name if not specified
o a LUN ID, which defaults to 0 if not specified
To provide support for NAS devices as quorum devices, the administrator must install the quorum device support module provided by Network
Appliance. If this module is not available, scconfprevents the addition of the quorum device. See Sun Cluster With Network-Attached Storage
Devices Manual for Solaris OS for instructions about obtaining the support module.
Additionally, the iSCSI license must be valid for the Network Appliance device.
OPTIONS
The following options can be used for NAS quorum devices. See scconf(1M) for the list of supported generic options. See scconf_quo-
rum_dev_netapp_nas(1M) for options that are specific to shared disk quorum devices.
The add and remove forms of the command are used to add and remove NAS quorum devices to or from the configuration. The change form of the
command is used for changing various properties of cluster quorum configuration.
Before you add a quorum device, you must set up and configure the device and the logical unit number (LUN) on the device to be configured
as a quorum device. For detailed procedures, see your Network Appliance documentation. For Sun Cluster requirements of device setup, see
Sun Cluster With Network-Attached Storage Devices Manual for Solaris OS. After the quorum device is added, you cannot change the type.
Add a NAS quorum device:
-q -a name=devicename,type=netapp_nas[,filer=filer-name][,lun_id=0]
Change a NAS quorum device's configuration:
-q -c name=devicename,{maintstate | reset}
Remove a NAS quorum device:
-q -r name=devicename
The -q option supports the following Network Appliance NAS-specific suboptions:
filer=filer-name
Specifies the name of the device on the network that you can use to access the NAS device when you are using rsh or telnet.
lun_id=0
Specifies the LUN ID on the NAS device that will be a NAS quorum device. The LUN ID defaults to 0.
When scconf is interrupted or fails while performing quorum-related operations, quorum configuration information can become inconsistent in
the cluster configuration database. If an inconsistency occurs, either run the same scconf command again or run it with the reset option to
reset the quorum information.
EXAMPLES
Example 1 Adding Network Appliance NAS Quorum Devices
The following scconf command adds the Network Appliance NAS quorum device qd1.
-a -q name=qd1,type=netapp_nas,filer=nas1.sun.com,lun_id=0
Example 2 Removing Network Appliance NAS Quorum Devices
The following scconf command removes the Network Appliance NAS quorum device qd1.
-r -q name=qd1
