Infoblox 2220 not coming out from rebooting cycle , its continuing rebooting..

[#1]

Hi ,

We have a Infoblox 2220 in our network , some time back we changed its rack and now its continuing rebooting and not able to start properly..

Please suggest how to resolve this issue

it is on production or not ? And do u have the Grid backup for this member?

if all yes, you can try to press "esc" + "enter" during the boot process. follow the screen when ask you to press both button. Once you in the emergency prompt, you can type reset database to clean up all the config and see it can come up or not. if stil cannot, suggested to open a tech case, request for RMA. Hope this can help.
