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".
