Best Practice for long term powered off blades

[DGillConsulting]

Hello,

I have several blades in UCS that we intend to leave powered off. We do not intend to remove the blades from the chassis at this time because we may power them back on in the future if we need them to meet demand. We want them powered off in the meantime to avoid unnecessary power consumption.

The UCS manager indicates several alarms because the blades are powered off, and our 3rd party monitoring tool (CA UIM) is throwing several critical alarms because we alarm when a blade isn’t powered on.

Decommissioning the powered off blades stops all alarms from UCS and from our 3rd party tool. The documentation seems to indicate we should decommission the blades while they are not needed.

Is there any reason we can’t/shouldn’t leave these blades in a decommissioned state for an extended period of time?

There is no problem with leaving them decommissioned for extended time frame.

Thank you, Kirk!

I wanted to make sure that they wouldn’t automatically acknowledge at some point and go back into production.

Hi Kirk,

Is it true that the act of decommissioning UCS Blades removes the profile and wipes the OS and boot partitions?

Will the UCS manager attempt to rediscover the slot since it sees, what is now, a new blade?

Thank you,

Dan
