This will setup a Virtual Switch Fabric or VSF on two switches that support this feature. Tested on a two 2930F 8 port. Switches are named Core-1 and Core-2
#disable all interfaces
interface 1-10 disable
#set port 8 as primary vsf uplink
vsf member 1 link 1 8
#specify vsf domain
vsf enable domain 1
#reload the switch, after reboot check vsf status
show vsf link
show vsf member 1
#on Core-2 get mac address and model
#provision core-2 as standby... all commands still done on Core-1.. #aka commander. Switch type is model number
vsf member 2 type <switch type>
module 2 type <switch-type> mac-address <macaddress>
#disable all interfaces on core-2,except uplink to core-1 -> core-2
interface 1-7,9,10 disable
#erase config and reload Core-2 after plugging in uplink to both switches
The following deletes all old kernels except for the current one in use.

If you have a small (less than 8 GB) USB drive available, upgrading AOS can be done via the USB port on a wireless controller. For the USB’s file system, FAT32 is an option for Windows users.
After booting into CPBoot (the second boot prompt)
#start the usb port
usb start 1
#check if usb port is reading
# to check if the file system is readable..
# ex. upgrade command
upgrade 0:0 1:1 Arubaimage/ArubaOS_72xx_184.108.40.206_53338

You can find the open source program on MrS0m30n3’s Repository.
For window users, look for the installer.
Service Fabric was officially released about a year ago with the promise that it would be ported to Linux. The first Linux port, which is a preview, is out. You can find the directions on getting it up and running here.
I was able to setup Service Fabric using Ubuntu Server 16.01 LTS running on Virtual Box. A few notes about this Service Fabric release:
- Allocate plenty of disk space. Running the service fabric cluster and installing everything (Azure CLI, Service Fabric SDK, Cluster Manager, OS) is 6.7 GB on my main user partition.
- Starting the server cluster does take awhile, about 4-5 minutes on my machine. You have to wait a few minutes after the script finishes setting up.
- The Yeoman Generator seen in the demo, azuresfcsharp, is in the Service Fabric SDK.

If you need to install a specific patch via the CLI from a local server, use the above command.
Found a tool on Code Project that exports MS SQL Server Database schema and data into a Sqlite database. This is done through a ADO.NET connection.
I could not get the latest source on Github to work with SQL Server 2014, but the original program posted on Code Project works fine.

From the CLI run:
dotnet build -r win10-x64
dotnet build -r osx.10.10-x64
dotnet build -r ubuntu.14.04-x64
dotnet publish -c release -r win10-x64
dotnet publish -c release -r osx.10.10-x64
dotnet publish -c release -r ubuntu.14.04-x64

It’s not completely obvious that upgrading the partition means upgrading the OS on the controller. Use this if the Web UI gives you an error about running out of space.
To upgrade partition 0 in enable mode:
copy tftp: <IP ADDRESSS> <FILENAME> system: partition 0
copy tftp: 220.127.116.11 A800_18.104.22.168_23915 system: partition 0
