4.8
SuperMicro Disk Drive Enclosures
o Due to an auto backplane detection issue with SuperMicro
SC836TQ enclosures, the red fault LED does not go on when
a failed member of an array is pulled from the enclosure,
for both SGPIO and I2C modes. WORKAROUND: Use the BIOS
utility to force the backplane type to I2C or SGPIO.
o 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 Seagate Barracuda 1TB SATA Drive
To ensure reliability when using Adaptec Series 2 and Series 5
controllers with a Seagate Barracuda ES.2 1TB SATA Drive
(ST31000340NS), Adaptec recommends using Seagate firmware
version AN05 or SN06 or higher.
4.10 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.
4.11 Online Capacity Expansion (OCE) and RAID Level Migration (RLM) Issues
o The system may fail to boot after performing a boot drive OCE/RLM.
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 BIOS utility to reselect the
proper boot device.
o After performing an OCE on a Solaris 10 U9 system, the OS
may fail to start if you pull a drive from the reconfigured
logical device before rebooting.
o Removing a member of an array while an OCE is in progress
can cause the array to be deleted.
NOTE: We strongly recommend that you do not remove any drive
during an OCE/RLM.
o This release supports a maximum of 8 concurrent OCE tasks in
the RAID array migration wizard. The following RLM and OCE
tasks are NOT supported:
- RAID 50 to RAID 5 RLM
- RAID 60 to RAID 6 RLM
- RAID 50 to RAID 60 OCE
4.12 Power Management under FreeBSD
The FreeBSD driver does not support power management in
this release.
4.13 Failed Arrays under FreeBSD
o On FreeBSD 7, deleting an array under IO load causes the
OS to reboot automatically.
o On FreeBSD 8, if an array fails (including pulling a drive
from the array), the firmware may crash causing the OS to
hang or reboot automatically.
4.14 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.)
