Power On and Booting the Server

Step 1: Logged in to your RMC

Step 2:  Check the state of the system. To view the partition configuration, enter show npar.

RMC cli> show npar pnum=0
RMC cli> show complex

If no errors are indicated, then proceed to power up the system.

If there are errors, run

RMC cli>show logs error

and resolve the errors before powering up the system.

Step 3: To power up the system, assuming it is configured with all chassis in one large nPartition numbered 0

RMC cli> power on npar pnum=0


  1. HPE Superdome Flex Server – Powering ON and Booting the Server

Powering Off SuperDome Flex System

Step 1: Power down the SuperDome Flex Server via OS

% shutdown -h now

Step 2: Log into the RMC as the administrator user, and enter the following command to power OFF the system:

RMC cli> power off npar pnum=0

To power RMC OFF a single partition, enter the following command:

RMC cli> power off npar pnum=x

Where x=nPar number.

If the above command is not workable, you may have to force power off

RMC cli> power off npar pnum=0 force

Step 3: Enter the following command, and verify that the Run State is OFF:

 RMC cli> show npar
 Partitions: 1

The Progress and the Future of AI

I really enjoy the presentation by Dr. Goh Eng Lim on the Future of AI. Really absorbing…..

Dr. Eng Lim Goh explains how AI’s predictive technology is being leveraged for our customers today. HPE is partnering with DZNE to use Memory-Driven Computing to find a cure for Alzheimers and with our supercomputing power we won in poker and created a commercial-off-the-shelf computer system to work in space. Also, Emily Kennedy from Marinus Analytics joins Dr. Goh to discuss fighting human trafficking using AI technologies and becoming a global company with the help of HPE. We are committed to help accelerate what is next for your enterprise.

Upgrading firmware for Super-Dome Flex

Step 1: Log into the HPE Superdome Flex Server operating system as the root user, and enter the following command to stop the operating system:

# shutdown


Step 2: Login to the RMC as administrator user, provide the password when prompted.

Use of DNS is recommended. If using DNS, verify that the RMC is configured to use DNS access by running:

RMC cli> show dns

If not, you may use the command “add dns” to configure DNS access (or you can’t use DNS).


Step 3: Enter the following command to power off the system:

If there is only 1 partition, partition 0 is the default:

RMC cli> power off npar pnum=0

In case of multiple partitions, enter show npar to find the partition number, then enter:

RMC cli> power off npar pnum=x

(where x is the partition number)


Step 4: Update the firmware by running the command:

RMC cli> update firmware url=<path_to_firmware>

Where <path_to_firmware>  specifies the location to the firmware file that you previously downloaded. You can use https, sftp or scp with an optional port. For instance:

RMC cli> update firmware url=scp://<version>-fw.tars
RMC cli> update firmware url=s<version>-fw.tars
RMC cli> update firmware url=<version>-fw.tars
RMC cli> update firmware url=<version>-fw.tars

Note: The CLI does not accept clear text password, the password has to be manually typed in.

Note: To use a hostname like ‘’, RMC must be configured for DNS for name resolution, otherwise you need to specify the IP address of ‘’ instead. See the command ‘add dns’ for more information.


Step 5: Wait for RMC to reboot after a successful FW update, then check the new firmware version installed by running:

RMC cli> show firmware verbose

Note: The nPar firmware version will not be updated until the next nPar reboot. See output under “DETERMINING CURRENT VERSION” below.


Step 6: Power on the system or partition:

– To power up a system configured with all chassis in one large nPartition numbered 0, enter:

RMC cli>  power on pnum=0

.- If you have multiple npars, each npar can be powered on separately using:

RMC cli>  power on npar pnum=x

, where x is the partition number.


Step 7: Determining Current Version:

To check or verify the current firmware levels on the system, from the CLI, enter the RMC command:

RMC cli>  show firmware
