Vada,

disks are only thrashing when you are very low in memory and your systems is permanently paging in and out.

Disks being busy up to 70% is normal on AIX and no reason for concern ... are you trying to investigate high IO waits from cpu? What kind of applications do you run?

I agree with DukeNuke, it would be more helpful if we could see your stats to tell you more than fishing in the dark.

NAME
gnome-disks - the GNOME Disks application SYNOPSIS
gnome-disks [OPTIONS] DESCRIPTION
gnome-disks is the command to launch the GNOME Disks application. Disks provides a way to inspect, format, partition and configure disks and block devices. The Disks application is single-instance. What this means is that if the application is not already running when the gnome-disks command is invoked, it will get launched and the command invocation will block until the application exits. Otherwise the existing application instance will be used and the gnome-disks command will exit immediately. OPTIONS
The following options are understood: --block-device DEVICE Switches to the Disks application and selects the block device given by DEVICE (for example, /dev/sda). --block-device DEVICE --format-device [--xid WINDOW-ID] Shows the "Format Volume" dialog for the block device given by DEVICE (for example, /dev/sdb1). If WINDOW-ID is given, makes the dialog transient to the given XID. --help Prints a short help text and exits. AUTHOR
