The purpose of this document is to assist a user in resolving management Browser User Interface ( BUI ) and Command Line Interface ( CLI ) connectivity/responsiveness issues.

If SSH to the appliance drops the user into the emergency shell, the end user must open a support session to allow the Oracle System Support team remote access to the system to troubleshoot and fix this issue.

To discuss this information further with Oracle experts and industry peers, we encourage you to review, join or start a discussion in the My Oracle Support Community - Disk Storage ZFS Storage Appliance Community
