2. Installation and Setup
2.1 Installation Instructions
The Adaptec SAS RAID Controllers Installation and User's Guide
contains complete installation information for the controllers
and drivers, as well as complete instructions for all
utilities. The Adaptec Storage Manager User's Guide
contains complete installation information for the Adaptec
Storage Manager software.
2.2 Power Management Setup
You must use a compatible combination of Adaptec Storage Manager
and controller firmware and driver software to use the power
management feature. All software components must support power
management. You can download the latest controller firmware
and drivers from the Adaptec Web site at www.adaptec.com.
2.3 Linux Setup
Page 2

readme.txt
Before installing the Linux operating system on a logical device,
Adaptec recommends clearing (removing) old data first. If you
do not remove old data prior to installation, the OS may
not boot. As a workaround, use the boot parameter 'aacraid.wwn=2'.
--------------------------------------------------------------------
3. General Cautions
- While an array is being built or cleared, do NOT remove and
reinsert any drive from that array. Doing so may cause
unpredictable results for any of the controller's arrays.
- While a drive is being cleared, do NOT try to include it in a
new array. Doing so may cause unpredictable results.
- DO NOT move drives containing an array or volume from one
controller to another while the power is on. Doing so could
cause the loss of the array configuration or data, or both.
Instead, power off both affected controllers, move the drives,
and then restart.
--------------------------------------------------------------------
4. Known Limitations
4.1 ACU Utility
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.
4.2 Creating an Array from the Adaptec Storage Manager CD
When you create an array with the Adaptec Storage Manager
bootable CD, the maximum size of the array is 2 TB.
4.3 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.
4.4 UnixWare and OpenServer
Adding or moving controllers in an existing UnixWare or OpenServer
system may cause some device resources to change, which may lead
Page 3

readme.txt
to the operating system being unable to boot. Currently, there
is no workaround available in the operating system. Before
installing the operating system, make sure all PCI devices are
either enabled or installed.
4.5 OpenServer 6.0
Arrays may not be displayed correctly, even after you restart
your computer.
To resolve the problem:
As root, run 'resmgr -r -m vtoc' until it fails. Then, as
root, run '/etc/conf/bin/idconfupdate -f'. Then, reboot.
4.6 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.
4.7 Hot-adding Disk Drives
o If you hot-add multiple disks simultaneously to a large
configuration (100 disk drives or more), it may take a large
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 at enclosure power on and 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 disk.
o If you remove a disk drive from an enclosure and that drive
is not part of any logical device, Adaptec Storage Manager will
not auto-detect the disk when the same drive is re-inserted
into the same slot in the enclosure. To correct the problem,
manually rescan the controller in ASM: right click the controller
in the Enterprise view, then select 'Rescan'.
Note that ASM will auto-detect the drive if:
- The same drive is re-inserted into a different slot
- A different drive is inserted into the same slot
4.8 SuperMicro Disk Drive Enclosures
If the controller does not detect disk drives installed in a
SuperMicro M28E2 Mobile Rack, use backplane SAS connectors
marked with "SAS In" only.
4.9 Using the Controller with a SuperMicro X7DBE Motherboard
The ASR-2405 and ASR-2045 do not support the SuperMicro X7DBE
motherboard. Adaptec recommends using the SuperMicro X7DBE+.
4.10 Using the Controller with a Seagate Barracuda 1TB SATA Drive
To ensure reliability when using Adaptec 2-series and 5-series
controllers with a Seagate Barracuda ES.2 1TB SATA Drive
Page 4

readme.txt
(ST31000340NS), Adaptec recommends using Seagate firmware
version AN05 or SN06 or higher. For low-port 5-series
controllers, use Seagate firmware version SN05.
4.11 Intel SE7525RP2 and SE7320EP2 Motherboards
The Intel SE7525RP2 and SE7320EP2 motherboards do not support
Mode 0 flash. These motherboards use 64-bit PCI addressing.
The AFU currently supports 32-bit PCI addresses only.
4.12 Windows Server 2008 64-Bit SCSIport Driver
The Windows Server 2008 64-Bit SCSIport driver is in the process
of being certified and is not supported in this release. Use
the Storport driver instead.
4.13 Boot Drive Failure after OCE/RLM
The system may fail to boot after a boot drive OCE/RLM (online
capacity expansion/RAID level migration). To correct the problem,
verify that the boot drive is still listed as the first logical
device in Adaptec Storage Manager (ASM). If not, use the
Control-A BIOS utility to reselect the proper boot device.
4.14 Online Capacity Expansion (OCE) Limits
This release supports a maximum of 8 concurrent OCE tasks in
the RAID array migration wizard.
4.15 Power Management under FreeBSD
The FreeBSD driver does not support power management in
this release.
4.16 Power Management with Seagate SAS Drive ST31000640SS
Power Management is not supported by the Seagate ST31000640SS
SAS drive. (The drive powers down but will not power up without
rebooting.)
4.17 Linux Cache Synchronization
With Linux driver 1.1-5-2459 (or higher), you may see an improvement
in performance if you suppress cache synchronization. For a
controller with battery back-up, add 'options aacraid cache=6' to
the /etc/modprobe.conf.local file. To completely suppress cache
synchronization, add 'options aacraid cache=2'. Then, reboot.
Note that the smaller value provides no protection in case of a
power outage.
