Removing A Disk Drive; Changing The Device Addition Policy - HP 4400 Replacement Instructions

6. For an impending failure, you must ungroup the disk before you
remove it:
NOTE:
You should 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.
CAUTION:
When selecting Ungroup in background, a
dialog box is displayed indicating 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 field
Figure 10 Monitoring ungroup progress
.
When the ungroup is complete, continue with the next step.
NOTE:
The ungrouping process may take up to several
hours to complete. The time 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 begin flashing to help you locate the

version.
