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, the memory DIMM module, 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.
