DESCRIPTION

Using the ROM-Based Setup Utility (RBSU) to disable HP Integrated Lights-Out 2 (iLO 2) Interrupt Request Lines (IRQs) on a ProLiant DL585 G2 or ProLiant DL385 G2 server may cause the system to stop responding before Power-On Self-Test (POST) occurs the next time the server is rebooted. No error messages are displayed.

SCOPE

Any ProLiant DL585 G2 or ProLiant DL385 G2 servers when iLO 2 IRQs have been disabled in the server RBSU.

RESOLUTION

Do not disable any iLO 2 IRQs in RBSU on the ProLiant DL585 G2 or ProLiant DL385 G2 server . If it is necessary to disable iLO 2, use the iLO-specific RBSU by pressing F8 during POST and disable iLO 2 from the Settings->Configure menu.

To recover from this issue if it has already occurred, the server must be reset by clearing NVRAM as follows:

For the ProLiant DL585 G2 server:

  1. Power down the server.
  2. Remove the server cover.
  3. Locate the System Maintenance Switch 11, position 6, and move the switch to the "On=Clear NVRAM" position.
  4. Power the server back on until Power-On Self-Test begins.
  5. After POST has started, power-cycle the server off.
  6. Move the System Maintenance Switch back to the "Off" position.
  7. Replace the server cover and power on the system. The server will boot normally.

For the ProLiant DL385 G2 server:

  1. Power down the server.
  2. Remove the server cover.
  3. Locate the System Maintenance Switch 7, position S6, and move the switch to the "On" position.
  4. Power the server back on until Power-On Self-Test begins.
  5. After POST has started, power-cycle the server off.
  6. Move the System Maintenance Switch back to the "Off" position.
  7. Replace the server cover and power on the system. The server will boot normally.

A future version of the System ROM will prevent iLO 2 IRQs from being disabled in the server RBSU. This advisory will be updated when the updated System ROM becomes available.
