Screencast

NetApp – Basic LUN Administration (7-mode) screen-cast

I have created another screen-cast which is a follow-up from my previous post NetApp – Basic Administration (7-mode) screen-cast
In this one I quickly go through Aggr, Volume creation. Later on I create a LUN, check the iSCSI configuration, configure igroup. Most of the job I perform in graphic interface – OnCommand System Manager. Later on I do some checks from the NetApp Command Line (CLI) to see if iSCSI session is established. From Windows 7 I attach the LUN to host, create a partition with NTFS filesystem and perform some test.
Very basic introduction to SAN/Block administration on NetApp 7-mode

All comments, questions, suggestions are as always very welcome.

NetApp – Basic Administration (7-mode) screen-cast

It’s been a while since I wrote anything about NetApp. Instead of going deep into any subject I decided to create a ~40 minute screen-cast with some very basic overview of a normal NetApp administration. This video is intended for rather less advanced admins (or even newbies to NetApp world) and I’m focusing mostly on GUI – OnCommand System Manager.

I started with showing how you can access NetApp filer – via GUI (Graphical User Interface) or CLI (Command Line). Later on I give a very short introduction to command line, and move on to the GUI – OnCommand System Manager.

Within GUI I’m starting with creating and explaining what is an aggregate. Later on creating flexible volume  that resides on this aggregate, qtree and set up some quota. Once this is ready I’m configuring CIFS Server and create CIFS shares plus additional NFS exports. Mounting those from both Windows and Linux host.

At the very end I give a very short introduction to iSCSI LUN as well, but for that topic I promiss to deliver a seperate video.

As always – all comments are most welcomed!

EMC VNX – VNX Snapshots and SMPs – screencast

I have created about ~20 minutes screencast about VNX Snapshots and Snapshot Mount Points.

Instead of a lot of theory explaination (which you can find for example here EMC VNX – Snapshots) I’m focusing on showing the basic functionality on two examples.

Example 1. I simulate a data loss from the host side, as an example new version of Software XYZ was released and instead of using the existing database file with your crucial data, it creates a new one, overwriting your existing data.

Example 2. This time you are smarter and you have a test environment on which you would like to test first the newer release of your software. But you need a copy, or image of your production data to make sure the test is valid. How to do that using Snapshots and SMPs technologies?
