Hello All,
I was wondering if anyone managed to change the LOM from shared to
dedicated using IPMITOOL on a HP system.
I am able to proceed at a Dell system using the raw commands:
To check if the current DRAC is "Shared with failover" or dedicated.
ipmitool raw 0x30 0x25
A result of 00 means shared and 02 means dedicated.
To change to shared:
ipmitool raw 0x30 0x24 0
To change to dedicated:
ipmitool raw 0x30 0x24 2

Best regards,
Danny Nieuwenhuis
