Configuring compute management settings
To configure the compute management settings:
1. Click Devices > Compute > View Details > Settings > Management.
2. Configure the password to access the iDRAC console and select IPMI over LAN to enable access from OME–Modular to
iDRAC, through BIOS.
Replacing compute sleds
The rip-and-replace feature of OME-Modular enables you to replace a failed compute sled, storage sled, or IOM, and apply the
configuration automatically.
NOTE: While replacing compute sleds, ensure that the:
● Compute sled is turned off and the compute nodes in the chassis contain PERC or HBA controllers.
● SAS IOMs and storage sleds are installed in the chassis.
● When you replace a compute sled, with a service tag, with a compute sled of another service tag, and the storage sleds are
mapped to the compute node slot, the power on the particular compute sled is turned off. An option to unblock power is
displayed on the Devices > Compute > Overview page for the compute sled.
● When you remove a compute sled, containing an HBA 330 controller with shared mappings, and replace it with a compute
sled containing a PERC controller, the sled is checked to ensure that no shared mappings exist. If shared mappings exist, a
message is displayed on the Devices > Compute > Overview page for the compute sled, prompting you to clear the
mapping. The compute sled is turned off.
● When you remove a compute sled containing a PERC controller with mappings, and replace it with a new compute sled
having an HBA 330 controller with a different service tag, a message is displayed on the Devices > Compute > Overview
page for the compute sled, prompting you to clear or accept the mapping. However, the compute sled is turned on in this
scenario.
The following flowchart and table illustrate the behavior of OME-Modular and the LCD panel on the chassis when the compute
sled is replaced:
