Snippet: NetApp SSH Keys for passwordless auth.

It really pisses me off when I have to type passwords over and over and over again. Even more so when I am trying to do a ton of work or do a deployment and I need to do it.

It’s even more annoying when a customer won’t enable proper access to their systems, or they use root forever with weak passwords.

Enter the SSH KEYs. Here is how to set them up on your NetApp in both 7-mode and Cluster Mode!

Tip #8: Set your damn host timeouts!

I saw a question on LinkedIn on the Netapp group today.

“what is the downtime (in seconds) for a FAS2240 high-availability machine in case one controller fails and the other takes over? ”

My pre-first cup of coffee answer was less on the question, and more on proper upkeep of a system running on a SAN/NAS. Any SAN/NAS. Set your damn timeouts on your hosts!

TIP #7: Using Netapp simulators to prepare for NCDA/NCIE exam

I am pretty active on LinkedIn with the NetApp groups there, and newbie NetApp admins are asking quite often lately about the NCDA exam.

Here are some helpful things to try out on the simulator. Every netapp admin should know them.

Tip #6: A better OSX terminal means better productivity.

First off, let me say that I live and breathe the terminal. Almost 2 decades playing in unix and linux gives me a strong love for it. I know I am more productive than a pointy clicky loser. BASH ftmfw! (and when I am stuck admin’ing windows systems, powershell, which I am not ashamed to say I have a newfound fondness for.)

Tip #5: Graphing performance data from Netapp – IN 3D!

I figured it was time to share some of the information I have posted before with graphing with powershell and also more advanced…

In the past, I had used 3D modeling in the Stats package R, to do 3D modeling of the CPU on a san. This is how!

Extending an existing LUN w/ Oracle ASM (on NetApp)

Below is a step by step of how I was able to resize an existing pun and ASM disk to a new size.

Oracle recommends for ONLINE disk group space increase to actually create a NEW LUN, and add it to the existing disk group. There have been a few bugs w/ ASM recognizing. If you do wan’t to attempt the resize method, you can attempt the instructions below on a test system. Things like this are why I typically recommend NFS. No partitions, no filesystems, none of the issues.

Scripted NetApp LUN Creation + Oracle ASM addition

I am constantly in new customer environments, setting up NetApp, Oracle RAC & ASM, NetApp SnapDrive, SnapManager for Oracle, etc on Linux…

While I know what I am doing in regards to storage and Oracle, most customers do not have a single point man (or woman) who knows all of these technologies and is the administrator to do day to day operations of them all. Also, when I have tried to teach the teams to do this, or if the DBA is in charge of all of these steps in a small environment, they typically get very confused when thinking about the relationship of the /dev/sd* and the multipath /dev/mapper/360* entries.

Easily convert/clean Powershell UTF-16 output to UTF-8 on Mac/Linux

I work with Powershell quite often. I make healthcheck systems for apps such as NetBackup, and others. I use it for day to day administration of NetApp and vmware.

One problem I always have with it jumping between customer environments is the fact that the default text output is UTF-16. This looks like a bunch of junk when I view it in terminal on my Mac, and also it is not easily grep’able, or less/more’able.
