2.2.1.5 Verifying Physical Drive Configuration

Check your system for critical, degraded, or failed disks.

To verify physical drive configuration, use the following command to verify the database server physical drive configuration:

Note:

If you are running Oracle Exadata System Software 19.1.0 or later, substitute /opt/MegaRAID/storcli/storcli64 for /opt/MegaRAID/MegaCli/MegaCli64 in the following commands:

/opt/MegaRAID/MegaCli/MegaCli64 -PDList -aALL | grep "Firmware state"

The following is an example of the output for Oracle Exadata Database Machine X4-2, Oracle Exadata Database Machine X3-2, and Oracle Exadata Database Machine X2-2:

Firmware state: Online, Spun Up
Firmware state: Online, Spun Up
Firmware state: Online, Spun Up
Firmware state: Online, Spun Up

The drives should show a state of Online, Spun Up. The order of the output is not important. The output for Oracle Exadata Database Machine X3-8 Full Rack or Oracle Exadata Database Machine X2-8 Full Rack should be eight lines of output showing a state of Online, Spun Up.

If your output is different, then investigate and correct the problem.

Degraded virtual drives usually indicate absent or failed physical disks. Critical disks should be replaced immediately to avoid the risk of data loss if the number of failed disks in the node exceed the count needed to sustain the operations of the system. Failed disks should be replaced quickly.
