The buttons alert the system to a request to bring the devices online.When the system acknowledges the request, it lights the OK indicators on the DPCC.The impact of validating the RAID devices is minimal.
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. Note: If additional virtual drives or a hot spare are present, then it may be that the procedure to reclaim disks was not performed at deployment time or that a bare metal restore procedure was performed without using the qualifier.
Refer to My Oracle Support note 1323309.1 for additional information and corrective steps.
The steps in the procedure assume that the Grid Infrastructure restart is disabled after the server restart.
The sample output shows Oracle Exadata Database Machine X2-2 database server with four disks.
The virtual device 0 should have four drives, and the state is To verify physical drive configuration, use the following command to verify the database server physical drive configuration: For Linux, use the following command to verify the database server physical drive configuration: . 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 If the output is different, then investigate and correct the problem.
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. If a drive in a database server RAID set is replaced, then the progress of the RAID set rebuild should be monitored.
They are configured as one 6-disk RAID-5 with one global hot spare drive by default.
There are eight disk drives in each Oracle Exadata Database Machine X5-8 and Oracle Exadata Database Machine X3-8.
Repair of the hard disks does not require the database server in Oracle Exadata Database Machine to be shut down.
