3. Check the disk Node World Wide Name against the error message UUID information recorded

earlier to ensure you have selected the correct disk (Figure 35).

4. Check the disk operational state. If a hard failure has occurred, the operational state should be

Failed. A disk with an impending failure indicates Good status until the cond ition of the disk

degrades enough to become a hard failure.

5. Verify that the Requested usage and Actual usage ﬁelds display Ungrouped (Figure 3 7).

CAUTION:

Both ﬁelds must display Ungrouped before you remove the disk.

If ﬁelds display Ungrouped, continue with Step 7. If you must ungroup the disk, continue with the

following step.

NOTE:

If the ﬁelds do not d isplay Ungrouped after you attempt to ungroup the disk, contact

your HP-authorized service representative for assistance.

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 sufﬁcientfreespaceisavailable.Afteryouungroup
