Solution 1684324.1 : SuperCluster: Possible Cell Disks Dropped When Deploying DB in Zones in an Existing DB in Zones Based Deployments with older OEDA versions

Applies to:

Oracle SuperCluster T5-8 Hardware - Version All Versions and later
Oracle SuperCluster M6-32 Hardware - Version All Versions and later
SPARC SuperCluster T4-4 - Version All Versions and later
Oracle Exadata Storage Server Software - Version 11.2.3.1.1 to 12.1.2.1.1 [Release 11.2 to 12.1]
Information in this document applies to any platform.

Symptoms

If using OEDA/ JOC from a version older than OCT 2014 you can inadvertantly destroy all underlying cell disks while undoing a failed zone creation or if rerunning either step 6 or 7 depending on version.

Cause

OEDA was never intended to be used post initial install and this SuperCluster requirement for post initial install use is an enhancement. that was completed in OCT 2014

Solution

Running OEDA or JOC older then OCT 2014 is not supported on SuperCluster please always try and use the latest version available.

This can be located in the OEDA table in Exadata Database Machine and Exadata Storage Server Supported Versions <Document 888828.1>
