Issue

  • The event log shows callhome.dsk.redun.fault: Call home for DISK REDUNDANCY FAILED

Node: node1
Sequence#: 583106
Time: 4/9/2026 01:58:33
Severity: ERROR
Source: dsa_disc
Message Name: callhome.dsk.redun.fault
Event: callhome.dsk.redun.fault: Call home for DISK REDUNDANCY FAILED
Corrective Action: Locate disks which have lost redundancy by using the following command: "storage disk show -fields disk,primary-port,secondary-name,secondary-port,shelf,bay" Note all channels with single path connectivity. Check for failures using these commands: "system health node-connectivity shelf show" and "system health system-connectivity shelf show". If a module or cable failure is identified, replace the failed module or cable. Confirm redundancy has been restored with the following command: "storage disk show -fields disk,primary-port,secondary-name,secondary-port,shelf,bay" If you need assistance, contact NetApp technical support.
Description: This message occurs when redundant access to disk storage is lost. This message and associated Autosupport are issued at most once per day. If your system is configured to do so, it generates and transmits an AutoSupport (or 'call home') message to NetApp technical support and to the configured destinations. Successful delivery of an AutoSupport message significantly improves problem determination and resolution.

  • System warning LED is illuminated
  • Disk 2.11.4 shows fewer paths than other disks, instead of the expected redundant paths
