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.
4.8 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 great
deal 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.
4.9 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.
4.10 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
(ST31000340NS), Adaptec recommends using Seagate firmware
version AN05 or SN06 or higher.
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 Using RAID10 under FreeBSD
If a RAID10 array fails under FreeBSD the firmware may crash
causing the system to reboot automatically.
4.17 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.)
4.18 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
