Firmware Update Notes - Sun Microsystems Sun Fire X4450 Configuration Manual

Firmware Update Notes

The BIOS and SP firmware are matched and, unless specified, should always be
■
updated in unison.
There are two types of SP firmware, ELOM (Embedded Lights Out Manager) and
■
ILOM (Integrated Lights Out Manager).
Before updating your server, you must know the type of firmware (ELOM or
■
ILOM) installed on the SP.
Do not update an ELOM-based SP using ILOM firmware. If you need to convert
■
an ELOM-based SP to an ILOM-based SP, use the ELOM-to-ILOM migration
process, which is described in the ELOM-to-ILOM Migration Guide.
Downgrading firmware is not recommended, because downgrading firmware
■
might eliminate important security and functionality updates.
Recovery procedures for failed updates are described in the product's Service
■
Manual.
