The following messages are Auto Service Request (ASR) alerts. ASR automatically submits a service request to Oracle Support Services in response to these alerts.

Information is also written to the system logs.

DISKALRT-02001 System OS hard disk failure

Cause: A physical disk that is hosting the operating system failed or an operating system RAID volume has lost redundancy. HDFS might also raise an alert.

DISKALRT-02002 System OS hard disk predictive failure

Cause: A physical disk that is hosting the operating system is in a state of predictive failure.

Action: Replace the physical disk as soon as possible. See "Replacing a Server Disk" and follow the instructions for configuring an operating system disk.

DISKALRT-02003 System OS hard disk poor performance

Cause: A physical disk that is hosting the operating system is performing poorly, which indicates that it is failing.

Action: Plan to replace the disk. If multiple disk disks in a server are identified as poor performers, then check for problems with the cable connections, the controllers, and the disk backplane before replacing the disks. To replace a disk, see "Replacing a Server Disk" and follow the instructions for configuring an operating system disk.

DISKALRT-02004 Data hard disk failure

DISKALRT-02005 Data hard disk predictive failure

Cause: A physical disk that is not hosting the operating system is in a state of predictive failure.

Action: Replace the physical disk as soon as possible. See "Replacing a Server Disk" and follow the instructions for configuring a disk for either HDFS or Oracle NoSQL Database.

DISKALRT-02006 Data hard disk poor performance
