"Power button" - what's the meaning of active or standby state for the blades?

Answered Question
Sep 1st, 2010

Hi,

If I want to power down one UCS B-Series Chassis, do i need to put the blades on standby via the "power button"?

I noticed there's a power button on each blades and it's orange/amber when there's no service profile association.


However, pressing on that button, it becomes green but when I press it again, it won't turn back orange/amber.

I've seen documentation mentioning green is active and amber is standby.

What the differents in terms of usage between active and standby if there's no service profile associated? I can pull out the blade even if the LED is green?

Many thanks.

I have this problem too.

The impact will be that you will have to "re-ack" the blade.  What I mean is there is a option in UCSM that allows you to re-acknowledge the blade you pulled, because if you think about it, the service profile has virtual componments attached to the profile so if you pull it, you will have issues.  Make sense?

Steven,

As long as there is not a service profile associated with the blade and if you go into the blade from the "equipment" tab and shutdown the server, you can pull it out and in as often as you like and if you do that on each blade then the entire chassis will be considered down.

Thanks.


What will happened if I just shutdown the blades without disassociating it with the service profile and remove it.. then reslot it back to the same slot..

What is the impact of doing this to the system?
