Re: Safely shutdown SimpliVity cluster with internal vCenter Server Appliance

Hello @jfc 

Normally you would shutdown all vms (or evacuate them) and shutdown the Omnistack controller  before shutting down the host. The recommended method to shutdown the Omnistack controller is to connect via putty (SSH) and run the command "svt-shudown-safe" and wait until it's down. 

Now, this command won't work when you you power off the VCSA VM so you need an alternate method. I would suggest doing the following: 

1. Work first on the hosts that don't have the VCSA running on them. 

2. Shutdown all VMs. 

3. Connect via putty to the Omnistack controller and run the command "svt-shutdown-safe". Wait until you see it turned off in vcenter. 

4. Put the node in maintenance mode and shut it down. 

 

For the host that has VCSA running on it:

1. Shutdown all VMs except OmniStack controller. 

2. Connect to the Omnistack controller via putty (SSH). Since VCSA will be down, you won't be able to use Vcenter credentials. Instead, use your svtcli account to log in. 

3. Once logged in, run these commands: 

-- sudo su

-- source /var/tmp/build/bin/appsetup

-- stop svtfs (wait until you get the prompt back and says "stop/waiting")

-- shutdown -hy now

This is going to shutdown the OVC gracefully. 

Continue and put this host in maintenance mode and shut it down. 

NOTE: The above procedure assumes you are running software version 3.7.3 or later. If you are on an older version you will need to contact support for assistance. 

Hope it helps, 

Gus
