New Features
This section lists the new firmware and TPM features.
New Features for 7.75 Firmware Release on the FFx Controller
1. Reboot On Crash
This parameter controls the behavior of the Automatic Restart on Failure feature,
and sets the following values:
• Maximum number of times a controller attempts automatic restart to recover
from firmware detected errors
• Minimum time interval that the controller must operate before refreshing the
number of restart attempts.
When a controller reaches the maximum restart attempts, the automatic restart
feature becomes disabled until the value is refreshed. Any subsequent firmware
detected errors require manual intervention to recover the controller. Possible
values for the maximum automatic restart attempts are 0 to 15 attempts (the default
setting is 3). Possible values for the time interval between refreshing the number of
restart attempts are DISABLED (never reset automatically) to 7 days.
2. Debug Dump
Debug Dump is enabled by default. When enabled, this feature records controller
state information when an abort occurs. After the abort has completed, the abort
information can be retrieved and analyzed to help determine why the abort
occurred. The information is generated while a controller abort is in progress and
recorded to NVRAM and a disk drive. TPM 1.2 would then be used to retrieve the
debug dump.
3. Hot Spare Polling
To increase data availability, the controller periodically reads and writes to online
spare drives to make sure they are operational. The polling period is not user
definable and set to once per 24 hours.
4. Instant RAID Availability (Background Initialization)
Background initialization makes the system drive instantly available for host read
and write access. This parameter is enabled by default.
