One of the ISV's Admins wants to remotely manage the HMC itself. That is, be able to remotely power-cycle the HMC, should it hang. In this case, the HMC is an x335. It is possible to install an RSA adapter into an x335/HMC? Will the HMC SW handle it? How about the BMC on the x335? Are any remote mgmt options supported?

And of course, the Admin reports the HMC did hang today...

Thanks.

I don't think IBM supports installing the RSA adapter on HMC.However, you can install the RSA adapter and do the power cycle.

Warning: HMC is running linux OS if you do the power cycle without proper shutdown.You may get into trouble.

Interesting thought.

I doubt IBM will support the HMC with an RSA and I'm sure the HMC code will not suport the RSA but that doesn't mean it won't allow you to reboot the machine with it.

The HMC code may just skip the adapter, fine if it does not cause the code a problem and should you need to reboot without access to the HMC interface this could be the way to go.

Considering pSeries machines are often managed remotely, in DR data centres, etc. this would be a handy feature.

Log a support call and ask. If they say 'not supported' then raise a DCR and let us know, we'll all raise support calls and apply for your DCR to encourage them to sort it out....

Considering that the newer (x336-based) HMCs already have an integrated BMC controller which can be configured to operate outside of the OS (i.e. you can shutdown the HMC, but can't power it back up remotely unless you've got the BMC configured), I'm going to say (completely my opinion only, as I have no official capacity to say yeah or nay to DCRs) that there's not much chance of getting support for the RSA adapter in the older HMCs.

Just my 2 cents.
