2. Installation Instructions
- The Adaptec SAS, SATA, and SCSI 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.
--------------------------------------------------------------------
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 Connecting to Adaptec Storage Enclosure 335SAS
The ASR-4000SAS controller does not support this
product.
4.2 Booting to a bootable CD
A system cannot boot to a bootable CD in a SCSI optical drive,
such as CD or DVD drive, connected to the ASR-2230SLP SCSI RAID
controller.
4.3 ASR-4000SAS/ ASR-2130SLP/ ASR-2230SLP controllers
ASR-3085/ASR-3405/ASR-3805/ASR-31205/ASR-31605 controllers
Use only the utilities/flash tools included with this release.
Upgrade any existing tools to those included with this
release, as this release supports additional features that
were not available with previous releases
4.4 ASR-2230SLP controller
With an Intel Pro/1000 MT 32-bit PCI NIC on the system, after
controller POST the controller goes to a
BLED 0xEF NMI_HANDLER_FAILURE.
4.5 ASR-4800SAS/ASR-4805SAS controller
When the controller is connected to an external enclosure,
only the internal SAS connector closest to the bracket is
available for use with internal SAS or SATA disk drives. The
other internal SAS connector shares the SAS bus with the
external connector, which is occupied.
Various devices on the serial bus can negotiate at different

speeds. To determine the speed at which a particular device
is negotiating, view the device properties in Adaptec Storage
Manager. (Click on the device, then click the Properties
button.)
4.6 Using the controller in a Dell Precision 530
When using the controller in a Dell Precision 530 with
Diskercise and Diskstress, data corruption/miscompares may
occur.
4.7 ACU utility
On some Intel and IBM systems, when you try to run the ACU,
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.
The ACU /C0 buildall command does not start a build/verify on
RAID 1 or RAID 10 arrays that are being created using the
quick init method.
4.8 FreeBSD
Adaptec Storage Manager is not supported in FreeBSD; storage
management must be done through the Adaptec Configuration
Utility (ACU) and ARCCONF command line utility.
4.9 Adaptec Storage Manager
After a rebuild and waking up from hibernation, a controller
may be detected incorrectly in Adaptec Storage Manager.
Press F5 to correct the problem.
4.10 ASR-4805SAS controller
When the controller is installed in PCI-E slot 2 of a
Dell PE 1800 system, there is no BIOS POST.
When the controller is installed in PCI-E slot 3 in a
Dell PE 1800 system, the system halts and the keyboard locks
up.
When the controller is set to boot from a RAID array and a
second RAID array is created, the controller may no longer
be able to find the boot drive.
When the controller is installed in the primary PCIe slot of
an Intel 955X or nVidia nForce4 (Intel edition) motherboard,
if you use the Adaptec Flash Utility to perform a Mode0 flash,
the controller will show incorrectly and cannot be flashed. If

a Mode0 flash is required, install the controller in an
alternate PCIe slot or alternate computer.
4.11 SAS and SATA controllers and Adaptec 335SAS enclosure
When the Adaptec 335SAS enclosure is attached to an Adaptec
SAS controller, such as ASR-4800SAS or ASR-4805SAS, the
enclosure numbering nomenclature starts with "0". For
example, if two Adaptec 335SAS enclosures are connected to a
ASR-4800SAS SAS controller, management tools such as Storage
Manager will denote the enclosures as "Enclosure 0" and
"Enclosure 1". When the Adaptec 335SAS enclosure is attached
to an Adaptec SATA controller, such as AAR-2420SA or
AAR-2820SA, the enclosure numbering nomenclature starts with
"14". For example, if two Adaptec 335SAS enclosures are
connected to an AAR-2820SA SATA controller, management tools such
as Storage Manager will denote the enclosures as
"Enclosure 14" and "Enclosure 15".
4.12 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.
4.13 Using the ASR-4800SAS in a Gateway 920
When more than one ASR-4800SAS controllers are installed in a
Gateway 920 server, the system will not POST.
4.14 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.
4.15 Using the controller with an Adaptec S50 JBOD Enclosure
Temperature warnings from Adaptec S50 JBOD Enclosure (firmware
version T016) are not shown in Adaptec Storage Manager (or on
the enclosure).
4.16 SMART errors on SATA controllers
During POST, SMART errors for disk drives connected to SATA
controllers are indicated as follows:
o N = No SMART errors reported
o Y = SMART errors reported
o N/A = Disk drive does not support SMART error reports
4.17 Firmware upgrades
Check your controller BIOS settings after upgrading the

controller firmware/BIOS, as the BIOS may have been reset to
its default settings during the upgrade.
4.18 RAID 10/50/60 array leg limitations
A RAID 10, RAID 50, or RAID 60 array cannot have more than 32
legs when created using the Build method. Maximum disk drive
count is only limited by RAID level. For instance, a RAID 10
array built with 32 RAID 1 legs (64 disk drives) is supported;
a RAID 5 array built with 32 RAID 5 legs (96 disk drives) is
also supported. Although you can create a RAID 10 array with
more than 64 drives using the Quick Init method, the maximum
number of build/verify operations that can happen at any one
time is 32; therefore, such an array could not be verified.
4.19 Microsoft VDS Storage Manager LUN Error
On some systems when creating a new LUN, the Microsoft VDS
Storage Manager for SANs snap-in may not work properly and
crash with an MMC snap-in error.
4.20 ASR-4805SAS controller
On Intel 945X or 955X motherboards with Mode0 set, the controller
is not recognized when installed in the primary 16x PCIe slot.
4.21 UnixWare and OpenServer
Adding or moving controllers in an existing UnixWare or OpenServer
system may cause some device resources to change, which may lead
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.
The individual behavior and affected devices will vary from system
to system. This is due to the different ways in which motherboards
may handle their PCI bus layouts, and how those layouts could be
changed when installing or rearranging devices. If the bus layout
changes and affects a critical system device (video, boot controller,
etc.) then the operating system may be unable to recover from that
change and be non-bootable.
4.22 ASR-31205/ASR-31605 with Sony SDX-470V tape drive
Backing up large files (800KB or larger) to a Sony SDX-470V
tape drive will generate an input/output error.
4.23 SATA disks do not support Dual Path with Expanders
Connect Dual Path SAS Enclosures with 2 Expanders only via one
Expander when using SATA disks, SATA disks do not support
Dual Path. If SATA disks are connected using 2 Expanders the
controller BIOS may crash.
4.24 DOS OS not supported

The DOS environment is supported for Adaptec tool execution only
(AFU.EXE and ACU.EXE).
4.25 ASR-4800SAS controller
Adaptec RAID 4800SAS is not supported on the Supermicro H8DME
system board.
4.26 DAT drive restoration fails when spanning tapes
When restoring from two or more tapes with a Sony SDX-470,
Sony SDX-570, or Quantum DLT V4 DAT drive, the operation aborts
automatically when restoring the second tape but gives the
(erroneous) message "Restore Operation has Completed".
