Solution 1632787.1 : Oracle Hardware Management Pack (OHMP) is not needed on Exadata

Applies to:

Exadata X3-2 Hardware - Version All Versions and later
Exadata X3-8 Hardware - Version All Versions and later
Exadata X4-2 Hardware - Version All Versions and later
Information in this document applies to any platform.

Symptoms

When connected to the ILOM web interface for either compute nodes or cell servers, the following message may be displayed:

Storage Status: Not Available

Comprehensive System monitoring is not available. Ensure the host is running with the Hardware Management Pack. For download details go to http://www.oracle.com/technetwork/server-storage/servermgmt/downloads/index.htm

Cause

This message is referring to the Oracle Hardware Management Pack (OHMP) which is a monitoring tool used for Oracle X86 Systems.

However OHMP is not installed on Exadata compute nodes or cell servers by default.

Solution

This message in the ILOM console is expected on Exadata and can be ignored.

Exadata uses different mechanisms for monitoring itself:

On the storage cell servers, the MS process monitors locally attached hard / flash disks and alerts on any failures.

On the database compute nodes it depends on the Exadata Image Version.

Pre 12.1.2.1.0 uses the exadata_mon_hw_asr.pl script monitors locally attached hard disks and alerts on any failures.

12.1.2.1.0 and later uses the MS service monitors locally attached hard disks and alerts on any failures.
