IPMI SoL on PowerScale nodes

IPMI SoL on PowerScale nodes

  • IPMI Serial over LAN (SoL) is enabled through the OneFS CLI, as explained in Configuring IPMI. Once enabled, PowerScale nodes (F200/F600) require additional steps for activating SoL on each node in a cluster.

    Configure serial devices

    In order for IPMI SoL to function, the physical serial devices must be configured to support SoL on each node in the cluster.

    Note: On PowerScale nodes, the physical serial port is no longer active after the BIOS configuration updates provided in this section.

    The serial communication settings should be configured per the values specified in the following table. For PowerScale nodes that do not have iDRAC configured, the serial communication settings are accessed during node boot up by selecting F2, entering the System BIOS, and selecting Serial Communication. For PowerScale nodes with iDRAC configured, the serial communication settings are found under iDRAC > Configuration > BIOS Settings. Update the serial communication settings per the following table and repeat for each node in the cluster.

    iDRAC SoL permission

    After the serial communication settings are configured, the IPMI username created in Configuring IPMI requires SoL permission through iDRAC. From the iDRAC Settings window, select the Users tab. Edit the IPMI username to have Serial over LAN enabled, as displayed in the following figures:

    The iDRAC settings must be updated on each PowerScale node in a cluster. Continue updating the iDRAC setting of each PowerScale node by accessing https://<node_IPMI_IP_address>:443.
