FC-SAS Bridge Health Monitoring collection is older than 24 hours

Applies to

  • ATTO FibreBridge
  • MetroCluster
  • ONTAP 9
  • Out of band management


FC-SAS Bridge Health Monitoring collection is older than 24 hours. The data collection for the FC-SAS Bridge is not current, and this will impact the ability to troubleshoot issues and indicate configuration issues.

Are FAS3240/V3240 and FAS3270/V3270 supported in MetroCluster running DATA Ontap 8.3 or later?

Applies to

  • FAS3240/V3240
  • FAS3270/V3270
  • ONTAP 8.3
  • ONTAP 9


FAS3240/V3240 and FAS3270/V3270 are not supported in MetroCluster running Data ONTAP 8.3 or later.

See the Interoperability Matrix for a list of supported configurations.

How to identify a mismatch of shortwave and longrange SFPs in a FC-VI card?

Applies to

  • MetroCluster FC
  • FCVI
  • long wave and short wave intermix


SFPs need to be the same for both ports on the FCVI card. The below procedure explains how to identify a mismatch.
In order to decide on the correct type of SFP you need to verify the infrastructure (cables / patch pannels) used in the datacenter.

Dynamic capacity expansion over asynchronous remote volume mirroring results in failed drives and failed volumes

Applies to

E-Series Controller Firmware 8.xx

E5500 running prior to firmware.
•    E5600 running prior to, or prior to firmware, or firmware.
•    E5700 running firmware.


When performing one of the following reconfigure operations on a volume group containing ARVM mirrors with PI enabled and a controller that supports multicore, the reconfigure operation can result in PI Reftag errors that lead to failed drives, failed volumes and failed reconfigure operations. Due to the volume failure during reconfiguration, the only way to recover is to delete the volume group. The data cannot be recovered by recreating the configuration.

Affected Reconfigure Operations:

  • Dynamic Capacity Expansion (DCE)
  • Dynamic Volume Expansion (DVE)
  • Dynamic Segment Sizing (DSS)
  • Dynamic RAID Migration (DRM)
  • Defrag

Check Active IQ if this impacts your systems

The following conditions must exist:

  • The system is running one of the platforms and affected releases listed in the Environment section (Multiple Core platform's only)
  • Volume Groups contain ARVM mirrors with PI enabled
  • A DCE, DVE, DSS, DRM, or Defrag reconfigure operation occurs on a Volume Group with PI enabled and ARVM mirrors
  • Traditional Volumes (DDP is not affected)

How to correct ACP partial connectivity and Single Path HA on a FAS22xx platform

Applies to

FAS2000 series


This article describes the procedure that should be followed to correct Alternate Control Path (ACP) partial connectivity and Single Path HA on a FAS22xx platform.

The following output is displayed:

NetApp Release 8.1 7-Mode: Thu Mar 29 13:56:17 PDT 2012
System ID: 1789379212 (ncdra00016n1); partner ID: 1789383578 (ncdra00016n2)
System Serial Number: 600000139685 (ncdra00016n1)
System Rev: B1
System Storage Configuration: Single-Path HA
System ACP Connectivity: Partial Connectivity

Note: Without any external disk shelves, the FAS22XX series controller has only one path to the disks on the internal shelf, and there is no connection to the ACP lock-wrench port e0P.
