iLO Redfish API

HPE server management with Redfish Redfish Examples

CURLing Redfish API for the iLO (iLO 5 in this example) looks like:

curl --insecure -u user:password --location https://<iLO>/redfish/v1/<rest_of_redfish_url>
curl example
mawenzi-06:~ # curl --silent --insecure -u root:<pass> --location https://mawenzi-05-ipmi.hpc.amslabs.hpecorp.net/redfish/v1/Managers/1/VirtualMedia/2/ | jq

ipmitool Guide

Prerequisites

Install ipmitool on a Linux server somewhere on the same network as the BMC you’re trying to control

zypper install ipmitool

Serial over LAN Console

  • Activate a Serial Over LAN (SOL) console:

    ipmitool -H <bmc_ip_address> -v -I lanplus -U <user> -P <password> sol activate

Chassis Commands

Chassis Commands:
  status, power, policy, restart_cause
  poh, identify, selftest,
  bootdev, bootparam, bootmbox

  • Show chassis status
