BSidesLV & DEFCON Conference Tips ** UPDATED 2016! **

Often before conferences, I tend to make a post for first timers. I never created one for BSidesLV or DEFCON before.

These are just my experiences and recommendations.

Do your own thing! Make the conference about what YOU want it to be about!

(That was tip #1)

I’ll be adding to this often as my brain remembers stuff.

A look at Netapp’s NDMP Cloud Extension Software (NCE)

Hey, you got a small Netapp? Hey, ya wanna do some backups to Amazon S3 or a compatible object storage system (aka Netapp StorageGrid Webscale)? NCE is for you!

The official blurb on it:

NDMP Cloud Extension Software (NCE) is a host-based utility that transfers data between Data ONTAP® storage systems and the Amazon® Simple Storage Service (Amazon S3) cloud. You can transfer data to Amazon S3 by using the ndmpcopy command. The ndmpcopy command is executed from a Linux host, which communicates with the storage system to transfer data to Amazon S3. Data transfer is supported at the volume, qtree, directory, or file level.

Quick Tip: Tuning many VMhosts for All Flash Arrays!

I needed a simple way to push some base tuning configurations to a large number of hosts in my lab.

Make this into a script called tune.sh. Update the naa.999 with the numbers your AFA SAN makes inside your vmware. (naa360 and others are common).

NetApp Cluster Mode TMP Volume type? Huh?

Late last night I was working on a very large CIFS and NFS migration for a customer. This was the culmination of a dual site FAS2050 7mode to FAS3220 cDot upgrade path.

I had originally planned on using the 7mTT (7-mode Transition Tool) to automate this migration. I went through the 7mTT install, core setup, and even planned a few volumes to be migrated by it.

Mid project, I decided against the 7mTT to do it manually. Though, many TMP type volumes were left around.

Just had someone ask me how they can delete all snapshots on a volume in cdot without being prompted for each snapshot to authorize it.

I told them powershell. Here’s a quick illustration of how to do it.

NDMPCOPY on NetApp 8.2.x Cluster Mode

So, I have a customer who I need to move 3 “boot from iscsi san” luns from a Netapp OnTap 8.2 Cluster Mode vServer shared with regular iscsi luns, to their own dedicated vserver. How do you easily move between vservers? NDMPCOPY!

Quick n Dirty Netapp LUN creation script

I am constantly having to pre-create or migrate massive amounts of LUNs in customer environments. I have many ways to go about it, powershell, ruby, but my awk script is my #1 way to do it

Imagine having to make luns for dozens of database instances on multiple hosts for dev/prod/qa. Suckage!

They all would follow a certain order and naming convention. Most of the sizes would be the same.

If I have to do anything once, I’ll probably have to do it again. So, script it! This will work in any shell with awk (osx/linux/solaris/CygWin)

NetApp Cluster Mode – Active Directory Authentication setup

Cluster mode is an awesome beast. I say beast, because everything takes MANY more steps to do. Say you want to just enable SSH or OnCommand System Manager client access to your base level cluster? Not so fast… there’s lots of steps before that.

In order to add active directory authentication to a Cluster Mode environment, you have to do the following:

  1. License CIFS
  2. Make a CIFS vserver
  3. Add an Authentication “DOMAIN-TUNNEL”
  4. Add User entries for every domain user + application + role
  5. Profit!

Here I will walk you through what it takes to create do all the crap I listed above.
