iLO MAC

BradV — Tue, 15 Sep 2020 13:19:57 GMT

I can't find the iLO MAC in the server hardware information. Am I looking in the wrong place? Since OneView talks to the iLO interface, it must know the MAC?

OneView does not inventory the iLO MAC address. The appliance only "knows" the MAC address if the iLO is on the same VLAN/Subnet and performs standard ARP lookup and maintains that information within the OS ARP table.

For what purpose do you need to know the iLO MAC address?

Hi Chris,

Just for inventory. We keep a confluence page with critical information for each server. I need the on-board MACs (which I can get easily from OneView) to populate our dhcpd configuration file. I guess I'll have to look to IPMI or hponcfg to pull in the iLO MACs. Thanks for the info!

I wouldn't suggest either. You can get an iLO SSO token from OneView. Then use iLO Redfish to get the MAC address:

/redfish/v1/managers/{item}/EthernetInterfaces/{item} where {item} is: /PermanentMACAddress /MACAddress

This is from the iLO Redfish REST API documentation.

Thanks Chris. I'll give that a try next week.

Hi Chris,

Not sure what I am doing wrong? I can't seem to get PermanentMACAdress directly, but can grab it with jq:

# Download all of the server hardware to a file. # Get session credentials for OneView. HARDW=hardw-all # Select server to query: SERVER=my-test-server-ilo UUID=$(jq -r '.members[] | select(.name == "'${SERVER}'") | "$.uuid)"' ${HARDW}) read iLOSSO iLOAuth <<< $(curl --insecure --header "X-API-Version: ${currentVersion}" \ --header "auth: ${sessionID}" --request GET ${OneView}/rest/server-hardware/${UUID}/remoteConsoleUrl | \ jq -r '.remoteConsoleUrl' | sed -e 's|hplocons|https|' -e 's|addr=||' -e 's|^\(.*$&sessionkey=$.*$|\1 \2|') MAC=$(curl --insecure --header "X-Auth-Token: ${iLOAuth}" --request GET ${iLOSSO}/redfish/v1/manaers/1/EthernetInterfaces/1/ | jq -r '.PermanentMACAddress')

which works. Just curious why --request GET ${iLOSSO}/redfish/v1/manaers/1/EthernetInterfaces/1/PermanentMACAdress/ returns Base.1.4.ResourceMissingAtURI?

Not sure. I copied straight from the Redfish API docs. If you get an HTTP 404 error, then it is likely a property of an object, not a relative URI.
