DNAC cluster faild

[jadon]

Hi everyone

   when the one member of dnac cluster had been faild , how resolve it? 

   I try reboot it , but service still kept restarting status.

it may take some time (a considerable time) after a reboot before all processes are running normally.

as this is posted sometime in the past, has this resolved itself by now ?

[jadon]

not resolve yet. I already reboot DNAC cluster , but one of cluster still not working .

You may need to ssh into DNAC and use CLI to check the update status then use CLI to resolve it. If it really get stuck, we need to delete it and download it again. 

The following pointers may help. You need admin privilege.
