I'm not an AIX/IBM expert but, talking generically, array degraded always means that there is no resilience because a disk needs replacing, or an array rebuild has failed for some reason e.g. the new disk does not have enough LBA's, has bad sectors, has also failed, or whatever.
Did the rebuild happen? Could you see substantial activity for a period? Or is that rebuild still running?????
Try re-seating the new drive again and initiate another rebuild.

gnome-disk-image-mounter
GNOME-DISK-IMAGE-MOU(1) gnome-disk-utility GNOME-DISK-IMAGE-MOU(1)
NAME
gnome-disk-image-mounter - Attach and mount disk images
SYNOPSIS
gnome-disk-image-mounter [--writable] [URI...]
DESCRIPTION
gnome-disk-image-mounter can be used to set up disk images. Both regular files and GVfs URIs (such as smb://filer/media/file.iso) can be
used in the URI parameter. If no URIs are given and a window server is running, a graphical file chooser will be presented.
Note that gnome-disk-image-mounter will not mount filesystems or unlock encrypted volumes in the disk image - this responsibility is left
to the automounter in GNOME Shell to ensure that the same interactions happen as if the disk image was a regular physical device or disc.
By default the disk images are attached read-only, use the option --writable to change this.
RETURN VALUE
gnome-disk-image-mounter returns 0 on success and non-zero on failure.
