With Samsung Spinpoint SATA drives, models HD103UJ/HD103UI/HE103UJ,
the controller can reset due to a timeout when the drive is under
heavy I/O load.
4.31 RAID Array Creation Issue With STEC MACH 8 SSDs
With STEC MACH 8 SSDs with firmware version 1766, RAID array
creation fails when using the Adaptec Storage Manager wizard.
WORKAROUND: Upgrade to the latest STEC firmware version to
resolve the problem.
4.32 Dual-Port SATA Enclosures
Dual-ported SATA enclosures are not supported in this release.
However, on Series 6 controllers (only), redundant paths to SATA
disks are detected in the firmware, but treated and shown (in ASM,
BIOS, etc) as two single path enclosures with the correct number
of drives. Although the drives are shown as available for
configuration, the configuration will fail. The firmware
currently supports dual path SAS drives only.
NOTE: Mixing SATA and SAS drives in the same logical device
is not recommended.
4.33 Xtore and Xyratex Enclosure Timeout
o With Adaptec Series 2, 5, and 6 controllers, Xtore XJ-SA12-005
and XJ-SA26-224R-S enclosures timeout when they receive a
Diagnostic Page 04 command. The error occurs at approximately
10 minute intervals (and is reported in the ASM controller
log file), but has little or no effect on performance.
o With Adaptec Series 5 controllers, Xyratex RS-1603-E3-EBD-2
enclosures periodically timeout when they receive a SES2
diagnostic command, due to a protocol violation. The error
occurs at 5 to 15 minute intervals, and may degrade performance.
4.34 Boot delay with Plextor PX-716SA DVD-ROM Drive
When booting from a Plextor PX-716SA DVD-ROM drive attached
directly to an Adaptec controller, the boot appears to fail
with a "Could not find boot CD-ROM" error, but resumes
and boots successfully if you wait approximately 30 seconds
or until the front LED light turns green.
4.35 Series 6 Controllers Hang on Warm Reboot on Some ASUS Motherboards
Due to a PCIe configuration problem with ASUS P7P55-WS, KCMA-D8,
and KGPE-D16 motherboards, Adaptec Series 6 controllers may hang
on warm reboot if installed in a slot with x8 links. (The problem
is not seen with Adaptec Series 5 controllers.)
WORKAROUND: Use a slot with x16 links.
4.36 Rebuild Watermark Lost with Hot-Plugged Enclosure
Disconnecting the enclosure cable while an array rebuild is in
progress resets the rebuild watermark to 0% complete. The
rebuild does not resume from where it left off when the cable
is reconnected.
4.37 HDA Mode Reset for Adaptec Series 6 Controllers
Adaptec Series 6 controllers do not support Mode 0 reset, using
the AFU utility on the Adaptec Installation DVD. To flash
a Series 6 controller using the HDA mode jumper on the controller
board, you must use the PFU.exe utility, which uses a FDL
firmware file (as opposed to a UFI file) to reset the board.
PFU.exe is available only from your Adaptec by PMC service
representative; it is not included on the installation DVD. For
the location of the HDA jumper on Series 6 controllers, see the
