Clustered Data ONTAP 8.

Description

This article describes the procedure that should be followed to enable remote access to a node’s root volume in a cluster.   

Clustered Data ONTAP does not export the node’s root volume using the SMB or NFS protocols.

With clustered Data ONTAP 8.0.x and 8.1, the contents of a node's root volume can be accessed by using Systemshell access and the diag user. Files from the root volume can then be read or copied off the node by using secure copy or ftp. This procedure is detailed here.

With clustered Data ONTAP 8.1.1, the above root volume access procedure still works. However, HTTPS read-only access is also provided to the log and coredump directory of each node in the cluster.

  • Note: With Clustered Data ONTAP 8.2.1 and newer versions, remote access is already enabled by default

HTTPS access to a node's root volume is available if the node is online normally or if it has been taken over by its HA partner.

The HTTPS access to a node's root volume is controlled by using the same authenticating username and password that is used for SSH or System Manager access, to administer the cluster.
