Raspberry Pi Zero W - Wireless Configuation

create the file under "boot" folder


ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev

once booted it is in /etc/wpa_supplicant folder

By default, the current version of Raspbian has SSH disabled. We're going to enable it here.

Create an empty file in the boot directory called ssh

Make sure that the file has no file extension, i.e. remove the .txt if you created the file by selecting New > Text File.

NetApp Portset / Multi-Pathing

Before we begin setting this up I recommend that your Windows system is updated and that you download the latest version of the NetApp Host Utilities. You can find this software package from and search in Software Download. Here is a snippet of what it looks like.

Let's begin, now log into System Manager on your FAS/AFF system. Navigate to the LUNs section and take a look at the initiator Groups as shown below:

From here you can see the list of initiators which are used for Fiber Channel connections. Now to add more physical connections click on Portsets are the top of the screen in the tab. As shown below:

So once you click on Portset name then click on Edit. This will pop up a list of physical ports in the cluster. Select all of the ports you want to join the portset and click save. Make sure all of the physical ports have been zoned to hosts and controllers.

Now we should check to make sure the Reporting node sees all of the ports we have just setu…

Console over SSH (ONTAP)

Recently I was working with a customer and our Professional Services people as we were doing an upgrade. If you want to view the console over SSH all you have to do is log into the Storage Processor and then run a command:
system console

NetApp ONTAP installation (Clean)

If you need to reset a NetApp FAS/AFF system back to the factory setting it is pretty easy. When you reboot the system connect to the console port on the controllers. Wait for the second "Ctrl-C" menu then press "Ctrl-C" to enter the menu below:

From here you can enter option "4" to do a clean configuration and initialize all disks.

NOTE: You should have both controllers on the same menu before proceeding with a full reset.

Another great feature of this menu is the Option 7, this allows you to upgrade the ONTAP software on the controllers. Engineers have used this to down rev or upgrade systems prior to joining a cluster.

vFoglight Cisco UCS Cartridge

Here is all of the code which you will need to get things running. I have stopped the development of this cartridge and turning it over to capable hands at Quest. Below are the files

vFoglight Alarms with Counts (Groovy Script)

Using the script editor located in Administration > Tooling > Script Console. Best to go ahead and save these for running at a later date when you need them. This will give you all of the alarms in the system along with the number of times it has triggered.
alarmService = server.get("AlarmService") currentAlarms = alarmService.getCurrentAlarms(); def alarms = [] as TreeMap; def result = new StringBuilder(); for (currentAlarm in currentAlarms) { def alarmName = currentAlarm.getSourceName() def alarmEntry = alarms[alarmName] if(alarmEntry == null) { alarms[alarmName] = 1 } else { alarms[alarmName] = alarmEntry + 1 } } for (alarm in alarms.entrySet()) { result.append(alarm.getKey()).append(" ").append(alarm.getValue()).append("\n") } return result

vFoglight Purge Stale Objects (Groovy Script)

Using the script editor located in Administration > Tooling > Script Console. Best to go ahead and save these for running at a later date when you need them. On line "10" you can enter the number of days to go back to remove the script below will purge objects "30" days old. Also on line "17" you can show the items to purge instead of deleting them.
// Script Purpose: Remove Stale Objects from vFoglight Database // Script Platform: Foglight Managment Servers running on Windows or Linux // Script Created by: // Script Last Updated: 10.13.2011 // Script Version: 11.10.13 // Please see PDF documentation that should have come with this script for usage information // Note: The script formating was compressed to save page space in the PDF. Sorry this does make it harder to read. // Modify the line below to change the number of days staleDays='30';// Exmple: Deleted object with stale data that is older than "30" …
