Adaptec ASR-5085 Information Sheet page 5

o For degraded arrays on Adaptec Series 6E controllers, the ACU
displays "junk' characters in the array properties list for
the missing drive.
o On some Intel and IBM systems, when you try to run the ACU
utility, this message appears:
"Not enough free memory to load the utility!
Press any key to attempt loading the utility forcibly
OR Wait for the system initialization to be completed
[Default]"
This is normal. On Intel systems, wait for the system
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.
4.3 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.
4.4 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.
4.5 SuSE Linux Enterprise Server 10
o SLES 10 cannot be installed on a >2TB array.
o If SLES 10 SP2 is installed on a bootable array 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.
4.6 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.
4.7 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.
