7.11 Settable Graceful Shutdown Timeout
The Set System Boot Options IPMI command along with the parameter #98 can be used
to specify the timeout for Graceful Shutdown persistently. The value of the graceful shutdown
timeout is specified for the CPU.
By default, this value is set to 10 seconds.
7.12 Local System Event Log
The ATCA-8330 IPMC supports a local System Event Log (SEL). The local SEL size is configured
to hold 1K entries in a circular FIFO buffer. Once the circular buffer is full, the next SEL entry will
overwrite the oldest SEL entry in the buffer. All events are automatically logged locally to the
local SEL before being passed to the Shelf's SEL.
To support the local SEL, a software emulated RTC (Real Time Clock) is enabled which upon
startup will request the local time from the shelf manager by sending an IPMI standard
command, Get SEL Time. Once the initial time is received, the IPMC maintains the time
locally and no further synchronization is performed with the shelf manager.
7.13 IPMI Hardware Watchdog
For crisis recovery purpose the IPMI building block provides a hardware watchdog. The IPMI
firmware will be resetted if it does not trigger the watchdog anymore.
