The dry run is a build-in self-running simulation mode
1. All configured hosts will be contacted
2. Credentials for the hosts will be tested
3. a protocol log will be written to log configuration issues as well as successful login tests.
4. The standard RCCMD shutdown signal is suppressed as long as simulation mode is active.
As long as dry run is active, no emergency shutdown is possible via any valid RCCMD server device.
Note:
If you change or adjust the standard scripts coming with a default installation or add new scripts, they will be executed
consequently. The Dry Run only suppress its own standard scripted shutdown sequence - it does not check the changes you
added manually.
This behavior contains advantages as well as disadvantages
1. Due to the fact your "sharp" scripts are executed mercilessly, the Dry Run test should take place beforehand!
2. By adding your own scripts that trigger harmless actions, you can check if your "sharp" scripts would work and all
administrative shares on the target system are met.
Part 2: Advanced settings
If Maintenance Mode (vMotion) is selected
RCCMD will present two addition menu entries:
Maintenance Mode Timout in Seconds
This value defines the time window that RCCMD grants the vCenter to move virtual machines to host that are not going down
into maintenance mode.
Virtual machines that have not been migrated within this time window will be left for shut down by the ESXi host.
vCenter credentials
In order to use vMotion, RCCMD need valid
vCenter credentials. Please note, an
RCMD client can shut down many hotsts,
but technically only maintain one vCenter. if
you need to configure several different
configuration types, it may be necessary to
use 2 RCCMD appliances that work
together.
Check values
Test the vCenter credentials. RCCMD will
try to log into the vCenter and give a
feedback including a reason why the login
attempt failed.
