Today (Saturday) We will make some minor tuning adjustments to MySQL.

You may experience 2 up to 10 seconds "glitch time" when we restart MySQL. We expect to make these adjustments around 1AM Eastern Daylight Saving Time (EDT) US.

NAME
isci -- Intel C600 Serial Attached SCSI driver
SYNOPSIS
To compile this driver into your kernel, place the following lines in your kernel configuration file: device scbus device isci Or, to load the driver as a module at boot, place the following line in loader.conf(5): isci_load="YES"
HARDWARE
The isci driver provides support for Intel C600 SAS controllers.
CONFIGURATION
To force legacy interrupts for all isci driver instances, set the following tunable value in loader.conf(5): hw.isci.force_legacy_interrupts=1
DEBUGGING
To enable debugging prints from the isci driver, set the hw.isci.debug_level variable to a value between 1 and 4 in loader.conf(5). The hardware layer in the isci driver has extensive logging capabilities which are disabled by default for performance reasons. These can be enabled by adding options ISCI_LOGGING to the kernel configuration file.
