User response
Run mmcommon recoverfs fileSystem to
ensure that the GPFS™ configuration
data for the file system is current. If some disks are still in a
non-ready state, display the states of the disks in the file system
using the mmlsdisk command. Any disks in
an undesired non-ready state should be brought into the ready state
by using the mmchdisk command or by mounting
the file system. If these steps do not bring the disks into the ready
state, use the mmdeldisk command to delete
the disks from the file system.
