FAS and V-Series Storage Systems Discussions

HA no longer configured on FAS 2552




We have two FAS 2552 arrays that were installed in 2015 a few months apart by the same engineer.  I was in the mgmt GUI and noticed that HA was not configured. "HA is not configured on this cluster."  I am almost certain that it used to be. On the other unit, HA is configured and it says "Both nodes can perform takeover on each other." I don't see any errors in the "System Alerts" list.


Is there a way for me to see if HA is configured, but just not working? Or if has ever been configured?


Thanks for any assistance you can provide!


Re: HA no longer configured on FAS 2552




If the cluster consists of only two nodes, "Cluster HA" should be enabled.


Could you please check this first:
cluster1::> cluster ha show
cluster1::> storage failover show


Please follow this recommendations:

Enabling cluster HA and switchless-cluster in a two-node cluster:


Reason I could think of having been disabled is: Engineer (you mentioned) might have performed 'node' reboot with "-inhibit-takeover true" parameter, which requires disabling cluster HA, however it must re-enabled, which may have been a miss.


Also, check the overall health of the cluster:

cluster1::> cluster show

Hi and thanks for your reply. Below are the results of the commands you asked me to run.


It seems like it should be safe to enable HA. However,  I'm on OnTap version 8.3,  is the procedure different than in the link you shared? That's for OnTap 9.


Thanks again!

Warning: Cluster HA is not working correctly. Make sure that both nodes are
healthy by using the "cluster show" command; then reconfigure cluster
HA to correct the configuration. Check the output of "cluster ha

reconfiguring cluster HA does not resolve the issue, contact technical
support for assistance.

Yes, the command should be same work 8.3 as well, you can enable it non-disruptively.


For 8.3 : Command is same.



Cluster looks healthy and Storage failover over looks ok .
