Error: Controller Memory Parity Error

Products

• Security Analytics

Issue/Introduction

This error may be seen in the SANtricity software.  Other possible errors that may show up in the Recovery Guru file are as follows: 

• RPA_ERR_CTL-Recovery Failure
• Volume not on preferred path due to AVT/RDAC failover
• Controller Memory Parity Error
• Loss of communication
• UNKNOWN_COMPONENT_STATUA-Recovery Failure

Cause

Either the cache battery or the whole controller needs to be replaced.  

Resolution

Generate a support log bundle using the following KB:  How to generate a support bundle for Dell MD3860 or NetApp attached storage

This will most likely require a controller replacement.  Each storage array has two controllers for redundancy and losing or replacing one controller should not cause any data loss or system downtime.
