7.9 IPMC Watchdog Timer Commands
The IPMC implements a standardized ‘Watchdog Timer’ that can be used for a number of
system time-out functions by System Management Software (SMS) or by the monitor. Setting
a time-out value of zero allows the selected time-out action to occur immediately. This
provides a standardized means for devices on the IPMB to perform emergency recovery
actions.
Boot Firmware
Boot Options (non-
volatile) 100 The IPMI system boot options command allows controlling the boot
process of a blade by storing boot parameters in IPMC non-volatile
storage. The boot firmware interprets the boot parameters during
power-up and executes the boot process accordingly. For detailed
information, see
BOOT FIRMWARE BOOT OPTIONS on page 193 .
Data 1 - Set Selector: Must be set to 0 (user area). You can only write to
the user area, therefore no other values are supported.
Data 2 - Block Selector: Zero based index of the 16-byte block which you
want to write to. Index 0 refers to the first block of 16 bytes, which
includes the first two bytes which indicate the boot parameter data
size.
Depending on the total length of the boot firmware data, your software
may need to write several blocks of 16 bytes in a row, each individually
addressed via the block selector.
Data 3 - n (n <= 18) Data which you want to write into the addressed
block. This will be a chunk of the boot firmware data. If less than 16
bytes are written, only the provided data is written, the remaining bytes
in the addressed storage area block are left unchanged.
