One new feature in 8.2.2+ that hasn’t been given much press (thanks to Curtis @ NetApp U) is the ability to boot directly into the boot menu or maintenance mode from the loader prompt. This feature will mainly be helpful for field personnel who frequently setup up and build out NetApp Clustered Data ONTAP systems. See below for a list of commands that are required to boot a cDOT system into each respective area. ...

Before I dive into Grafana I wanted to make a quick note that last week marked my 1 year anniversary at NetApp. This year has honestly flown by and it is hard to believe as it feels like just yesterday I started this new adventure with various unknowns. It has been a year full of change along with many new experiences which I feel have made me stronger, both as an individual and professional. I am thankful for the opportunity at NetApp and for the ability to work with so many great customers that have turned to us to solve their most critical of IT issues. I look forward to the challenges that lay ahead and for many more years with this great team at NetApp. ...

Today is hump day and with that comes some added motivation to update this blog with some new material! The following post discusses another common topic and that is the termination of CIFS sessions in cDOT. This task could be performed in 7-mode however the commands have since changed in cDOT. Refer to the following tutorial below to kill any unwanted CIFS for a specific Windows user: Display the current CIFS session(s) for the user and record the value(s) in the “Connection ID” column ...

After spending the last few weeks moving into my new place and having “fun” furnishing it, I am back on the road armed with more content! Within a few hours of being onsite today I got asked if it was possible to set NTFS permissions to files and/or folders within Clustered Data ONTAP (cDOT). This is another commonly asked question and the answer to it is yes, you can apply NTFS permissions to filesystem objects from within cDOT. Below I have included a summarized step by step tutorial on how to apply NTFS permissions to a given path (can be the root of a volume or a file or folder which resides within a cDOT volume): ...

With a snap of the fingers I have been at NetApp for almost 6 months already! I have been quite busy acclimating to life as a consultant as I have been in the field almost 100% of the time since May. While being busy has been nice, it has left me with little time to update this blog. Fortunately, I have finally discovered some late night motivation (caffeine) and will be publishing several articles in the coming days regarding topics which I commonly deal with in the field. ...

You cannot simply attach the restored VMDK, mount the filesystem, and copy the directories or files due to the way LVM utilizes UUIDs for logical volumes. In order to restore directories or files from a LVM-based RHEL 6 VMDK, please perform the following steps: Restore the VMDK either using the backup product of choice ...

I recently ran into an issue where I was could not unmount an empty vSphere datastore from the appropriate hosts. After doing some research I found out that this issue was caused by open files from a new VSAN-related service known as “vsantraced”.

I have run into a few scenarios where I have had to manually clear NFS locks on a given NetApp system. The recommended procedure for clearing these locks has changed over the years depending on the Data ONTAP version and now again with the release of Clustered Data ONTAP. 7-mode ONTAP Login to the appropriate 7-mode filer Transition into diag mode priv set diag Clear all the NFS locks ...
