ATCA-7480 Installation and Use (6806800T17A) 235
This timer specifies how long the IPMC waits for the payload to shut down. If the payload
software does not configure its OpenIPMI library to be notified for shutdown requests, the
IPMC shuts down the payload when the timer expires.
8.1.7.1.3 System Boot Options Parameter #100
The system boot options parameter #100 allows you to send multiple boot options to the
blade’s boot firmware and thus control the boot process. The boot options which you can
configure using this parameter are typically a subset of the boot options which you can
configure in the boot firmware directly, for example, using a Setup menu.
The IPMC contains a storage area where the boot parameters are stored. When the blade
boots, the boot firmware reads out the storage area, interprets the parameters and executes
the boot process accordingly.
The storage area is divided into two parts: the default area and the user area. The user area can
be read and written by an IPMI user and default is, the area which the boot firmware reads out
and uses during the boot process. The default area can only be read by both the IPMI user and
the boot firmware. Its purpose is to store factory-programmed default boot options which can
Table 8-10 System Boot Options Parameter #98
Bit Description
15:8 Timeout for GRACEFUL_SHUTDOWN, LSB (given in 100 msec)
7:0 Timeout for GRACEFUL_SHUTDOWN, MSB (given in 100 msec)
The System Boot Options parameter #98 is non-volatile. During blade production its data is
initialized to 0xFF and its state is set to invalid. Its parameter data remains preserved after
IPMC power cycles and firmware upgrades.
The boot parameters in the IPMC storage area have higher priority than the same boot
options, which may be configured in the firmware itself, for example, using the setup menu.
