Which two options should be used to identify a damaged or failing flash card on an X6 Database Machine highcapacity storage server?
A.
Using the CELLCLI CALIBRATE command on the storage server after logging in as the root user
B.
Using the CELLCLI LIST LUN DETAIL command as the celladmin user
C.
Using the CELLCLI CALIBRATE command on the storage server after logging in as the celladmin
D.
Hardware monitoring using the storage server ILOM
Explanation:
The CALIBRATE command runs raw performance tests on cell disks, enabling you to verify the disk performance before the cell is put online. You must be logged on to the cell as the root user to run CALIBRATE.
Oracle ILOM automatically detects system hardware faults and environmental conditions on the server. If a problem occurs on the server, Oracle ILOM will automatically do the following:
Illuminate the Service Required status indicator (LED) on the server front and back panels.
Identify the faulted component in the Open Problems table.
Record system information about the faulted component or condition in the event log.
