will a management network restart affect virtuals on a IBM Blade?

[Tracyp]

Hello all

We are currently running an IBM Blade S with two HS22 blades that are on ESX 4

I want to add an HS23 which is on ESXi 5 and then upgrade all three blades to the latest ESXi 5 release.

I have gone into the HS23 console and set up the name / networking details. When I exit I get a message saying that the management network will be restarted.

Will this restart have any affect on the currently-running virtuals on our existing blades? Do I need to shut them all down first? if so thats a bit of a pain

thanks

Tracy

Management network only affects that hosts network to talk to other hosts or to connect to it but should not affect any guests on that host or any other host.

Hello, i think that your question is independetly of the hardware.. are you looking that in host DCUI ?

looking at the HS23 host console

[vJJSosa]

DCUI is the "graphical" ESXi console, like a BIOS setup.

Check this KB for more information about restart mgmt network: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=100349...

Note: "Caution: Ensure Automatic Startup/Shutdown of virtual machines is disabled before running this command or you risk rebooting the virtual machines..."

Hope this helps you

vJJsosa does have a good point if the Ensure automatic startup/shutdown is turned on it will bring down machines, but in esxi I believe 5 and up that is disable by default. See screenshot:

It's per system, in your case blade specific, so no, you can easily do this.
