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.
