How to non-disruptively create a new root aggregate

This article describes the procedure that should be followed to create a new root aggregate non-disruptively and have it host the root volume in clustered Data ONTAP 8.2 and 8.3 and ONTAP 9.0systems. This feature allows the root aggregate to be hosted on a thin partition using disks that are shared for data aggregates. On system initialization, 12-24 disks are divided into a large ‘P1’ partition for data and into a small ‘P2’ partition for the root. Only re-initializing each node (option 4) will place the root aggregate onto shared disks and it is not possible to do this non-disruptively. However, it is possible to non-disruptively move the root volume off ofRead More

How to capture packet traces (PKTT)

It is important to specify -d /etc/crash in the pktt commands so that the traces are saved to disk and in a location that is easy to access.  If you do not specify the -d option, the traces will only be written to disk if you use the pktt dump command. The pktt start all command starts capturing packets on all physical and VLAN ports that are online. Examples: ::> node run -node <node_name> pktt start all -i <ip_addr> -i <ip_addr> -i <ip_addr> -d /etc/crash This will start a packet trace on all interfaces on the node specified, and will capture any packet that has a source or destination of one of the IPs specified withRead More

Setup ADP

Perform the following steps: Install Clustered Data ONTAP version 8.3 or higher Bring both the nodes to Maintenance mode and un-own all the disks Depending on the state of the storage system you may need to release disk reservations and destroy mailbox disks first (run on each node while in Maint Mode): storage release disks mailbox destroy local mailbox destroy partner disk remove_ownership all (this will remove the ownership of all disks attached to the system) Confirm all disks unowned: disk show (you may need to do the command twice) Halt both nodes Set the environment variable on each node: setenv root-uses-shared-disks? true (The ? in the command is required. DO NOT remove it)Read More

Set up CIFS auditing with clustered Data ONTAP

Starting from clustered Data ONTAP 8.2, native auditing is implemented and it provides a file auditing framework that supports both CIFS and NFS protocols. The following is an example showing how to implement CIFS auditing with clustered Data ONTAP: For setting up CIFS auditing in Data ONTAP 7-Mode, see article 1011243: How to set up CIFS auditing on a Data ONTAP 7-Mode controller. Pre-requisites: Cluster Vserver: cm3220a-cn Data Vserver: vs_cifs vol1 is mounted as /vol1 audit is a folder in /vol1 Perform the following steps: Create an Audit Policy: The first step for enabling auditing on a Vserver is to create an audit policy. Vserver name and destination path for saving logs and log rotation parameters areRead More

How to renew an SSL certificate in clustered Data ONTAP

Perform the following steps: Check the current certificate status. Enter the privilege mode: cm2244a-cn::> set -privilege advanced cm2244a-cn::*> security certificate show Note: In clustered Data ONTAP 8.2 and 8.3, this command is available in the admin level. The CLI output will also provide the serial number in clustered Data ONTAP 8.2 and 8.3.
