HP Disk Drive Replacement Instructions (5697-1679, June 2012)

4. Verify the disk operational state. If a hard
failure has occurred, the operational state
appears as (Failed). A disk with an
impending failure indicates Good status until
the condition of the disk drive degrades
enough to become a hard failure.
5. Verify that the Requested usage and Actual
usage boxes display Ungrouped
(Figure 9 (page 4)).
Figure 9 Verifying disk group status
CAUTION: Both fields must display
Ungrouped before you remove the
disk drive.
If both fields display Ungrouped, proceed
to Step 7.
Otherwise, continue with Step 6.
6. For an impending failure, you must ungroup
the disk before you remove it:
Only ungroup one disk at a time. Before you
ungroup a disk, verify that leveling is not in
progress and that sufficient free space is
available. After you ungroup the disk, verify
the status of the disk group before continuing.
For more information about leveling and free
space, see the Enterprise Virtual Array
configuration best practices white paper for
your array model.
a. Click Ungroup.
b. Click Ungroup in background.
A dialog box indicates that the
Operation succeeded. This indicates that
the ungroup operation has been
initiated. You can monitor the progress
of the ungroup on the Disk Drive
Properties window.
c. Click the Disk Drive tab and monitor the
ungroup progress in the Migration
progress box (Figure 10 (page 4)).

When the ungroup is complete, continue
with Step 7.
The ungrouping process can take up to
several hours to complete. The duration
depends on the capacity of the disk and the
level of storage system activity.
If, after attempting to ungroup the disk, the
Requested usage and Actual usage boxes do
not display Ungrouped or the Migration
progress box does not display 100%, contact
your HP-authorized service representative for
assistance.
7. Click Remove to prepare the disk for
removal. The status indicators on the disk will
flash to help you locate the disk. You can
now proceed to “Removing a disk drive”
(page 5).
