initialization to be completed. Then the ACU will run. On IBM
systems, press any key when prompted to load the utility
forcibly.
o The ACU erroneously displays deleted logical drives in the
JBOD list. The logical drive(s) continue to appear in the
JBOD list until you delete all of the JBODs.
o With some enclosures, the ACU displays incorrect box/slot
information for managed disk drives; for example,
Exp/Phy instead of Box/Slot.
4.2 AFU Utility
o When running the AFU in Menu Mode, you can update (flash) only
one controller at a time. You must reboot the system before
updating the next controller.
o Flashing a Series 5 high-port controller (51245, 51645, 52445)
with down-level firmware and an older version of the AFU crashes
the system. To recover, you must use a Mode 0 reset using the
latest firmware version. See the user's guide for details on
the Mode 0 reset method.
4.3 Creating an Array from the Adaptec Installation DVD
When you create an array with Adaptec Storage Manager in
bootable-CD Mode, the maximum size of the array is 2TB.
4.4 SuSE Linux Enterprise Server 10 with Service Pack 2
If your boot array is installed on the controller, and the boot
OS is SLES10 SP2 with driver version 1.1.5-2458, you must add
'aacraid.wwn=1' to the kernel boot command line. Alternatively,
install the latest aacraid driver.
4.5 Using the Controller with an Adaptec S50 JBOD Enclosure
Temperature warnings from the Adaptec S50 JBOD Enclosure with
firmware version T016 are not shown in Adaptec Storage Manager
(or on the enclosure). To correct the problem, upgrade to the
latest firmware version.
4.6 Hot-adding Disk Drives
o If you hot-add multiple disks to a large configuration (100
disk drives or more), it may take a significant amount of
time before those disk drives appear in Adaptec Storage Manager.
o With Intel Backplanes AXX4DRV3GEXP and AXX6DRV3GEXP, if a drive
bay is empty when the enclosure is powered up, then a SATA disk
drive is hot-added into the empty bay, the controller does not
detect the new disk drive. To work around this issue, remove
and re-insert the SATA drive.
4.7 SuperMicro Disk Drive Enclosures
o Due to an auto backplane detection issue with SuperMicro
SC836TQ enclosures, the red fault LED does not go on when
a failed member of an array is pulled from the enclosure,
for both SGPIO and I2C modes. WORKAROUND: Use the BIOS
utility to force the backplane type to I2C or SGPIO.
o If the controller does not detect disk drives installed in a
SuperMicro M28E2 Mobile Rack, use backplane SAS connectors
marked with "SAS In" only.
4.8 Using the Controller with a Seagate Barracuda 1TB SATA Drive
To ensure reliability when using Adaptec Series 2 and Series 5
controllers with a Seagate Barracuda ES.2 1TB SATA Drive
