Solution 2259069.1 : FCO A0380-1: Proactive: Issues with the FS1-2 Controller Resource Exhaustion may Lead to Loss of Data Access

Applies to:

Oracle FS1-2 Flash Storage System - Version All Versions to All Versions [Release All Releases]
Information in this document applies to any platform.

Symptoms

Controller restarts may occur on FS1-2 systems running system firmware version 6.2.10 or lower. This can lead to the Controllers hanging on restart and impacting system availability.

Impact:

Issues with the FS1-2 Controller resource exhaustion may cause one or both Controllers to go offline. This could lead to loss of data access.

Changes

Contributing Factors

This issue can occur on any FS1-2 Flash Storage System that does not have system firmware version 6.2.11-457-04 (or later) installed.

Note: Customers who successfully upgraded to 6.2.11 do not need to upgrade to 6.2.11-457-04 as the fixes in 6.2.11-457-04 were cosmetic related to invalid compatibility warnings.

Cause

The transport mechanism between Controllers and Pilots may run out of resources causing the Controller to restart. This can also result in the Controllers hanging on restart and impacting system availability.
