Installation manual

15 ATTO Technology Inc. ATTO Utilities Installation and Operation Manual
1.4 ExpressSAS, ThunderLink SH and
ThunderStream SC NVRAM Settings
The settings in the NVRAM tab vary depending upon the selected storage controller and the operating system.
ATTO storage controllers are designed to operate
properly using factory settings. Entering invalid or
incorrect settings when using an NVRAM
configuration utility such as the ATTO ConfigTool may
cause your storage controller to function incorrectly.
CAUTIONCAUTION
Back up system data when installing or
changing hardware configurations.
Use caution when making changes to NVRAM
settings and only make changes to those with which
you are familiar. Once you have made the desired
changes, click
Commit to save the changes.
Changes do not take effect until you reboot the
system.
If you do not want to make any changes, you may
choose one of the following:
• Defaults: restores the storage controller to
factory default settings. The Commit button
must be clicked to save any changes.
• Restore: reverts to the NVRAM settings saved
the last time the Commit button was used.
Clicking Commit is not necessary.
SAS Address
Read only
Displays the SAS address assigned to the storage
controller. The value cannot be modified.
Boot Driver
Choices: enabled, scan only, disabled
Default: enabled
If enabled and disk drives are detected during the bus
scan, the BIOS driver remains resident. If disabled, the
BIOS starts, resets the storage controller chip and
unloads the driver.
If
Scan Only is selected, the BIOS driver scans the bus
and displays the devices attached, then unloads itself
after a brief delay.
Heartbeat
Choices: enabled, disabled
Default: enabled
When enabled, requires the firmware to respond to
periodic activity. If the firmware does not respond, the
system driver resets the firmware on the storage
controller.
NCQ
Choices: enabled, disabled
Default: enabled
When enabled, the storage controller driver sends
multiple simultaneous commands to NCQ capable SATA
disk drvies.
Phy Speed (6Gb SAS/SATA storage controllers
only)
Choices: Auto, 6Gb/s, 3Gb/s, 1.5 Gb/s
Default: Auto
Allows the user to manually adjust the speed of the PHY.
Drive Wait Time
Choices: 1-255 seconds
Default: 3
Specifies the number of seconds which the driver waits
for devices to appear.
Device Wait Count
Choices: 1-255 devices
Default: 1
Specifies the number of devices which must appear in
order to cancel the
Drive Wait Time period.
LED Control (R608, R60F, H608 & H60F only)
Choices: SGPIO, I2C, Disabled (H6XX only)
Default: SGPIO for R6XX, disabled for H6XX
Specifies the method used to perform LED control. The
storage controller exposes a virtual SES device that
provides standard SCSI SES commands for LED control.
The standard SCSI commands can control the locate and
failure LED. The virtual SES driver will use the specified
method to send the commands to the drive backplane.
See the ExpressSAS installation manual for instructions
to connect cables for SGPIO or I2C LED control.
