to report the maximum PHY rate (3.0Gb/s), not the
reduced rate. For high-port controllers, the PHY rate
is reported correctly.
4.23 PHY Rate Limitations on SSDs in HP Proliant Backplanes
With SSDs attached to a HP Proliant SE326M1 Backplane, setting
the PHY rate below 3.0Gb/s (or 'Auto') results in a Kernel Panic,
causing a BIOS timeout and firmware crash.
4.24 Changing the Stripe Size for Large RAID Arrays
For large RAID arrays, a RAID-level migration may fail with a
firmware crash if you reconfigure the array with a different
stripe size. No data is lost, however.
Known migrations that result in a FW crash include:
o 16/32/64/128 drive R0- 256/16 to 16/256 stripe change
o 16/32/64/128 drive R0- 512/16 to 16/512 stripe change
o 16/32/64/128 drive R0- 1024/16 to 16/1024 stripe change
o 16/32 drive R5- 16 to 512/1024 stripe change
o 16/32 drive R5- 512/1024 to 16 stripe change
o 16/32 drive R6- 1024/16 to 16/1024 stripe change
4.25 Hot-Adding maxCache SSDs
If you remove two or more maxCache SSDs then re-insert the
drives at the same time, only one will be recognized as part
of the maxCache pool. To reconstitute the pool, use Adaptec
Storage Manager or the BIOS utility to reconfigure
the maxCache cache.
4.26 Some SSDs Appear as SATA Drives
Some solid state drives (such as the MemoRight MR25.2-S032G)
identify themselves as ROTATING media. As a result, these SSDs:
o Appear as SATA drives in the ASM Physical Devices View
o Cannot be used as Adaptec maxCache devices
o Cannot be used within a hybrid RAID array (comprised of
SSDs and hard disks)
4.27 Mismatch in RAID x0 creation in BIOS and ASM
The BIOS utility creates RAID x0 arrays with an odd number of
drives by default. Adaptec Storage Manager creates RAID x0
arrays with an even number of drives by default.
4.28 WDC WD3200BJKT-00F4T SATA Drives with Promise J630 Enclosures
A compatibility issue between Western Digital WD3200BJKT-00F4T
SATA drives and Promise J630 enclosures can result in a firmware
crash during a RAID array build or bus rescan.
4.29 SATA 6G Drives Not Detected on Promise and Intel Backplanes
o With Promise J830s enclosures, SATA 6G drives are reported as
3G in ASM and the BIOS utility, due to a speed negotiation
issue between the drive and the expander.
o With Adaptec Series 5 controllers and a Promise J830s enclosure
running Firware version v6.12, SATA 6G drives cause the
BIOS to hang. WORKAROUND: use firmware version v6.04.
o With Intel AXX6DRV3G and AXX6DRV3GEXP backplanes, SATA 6G drives
are not detected in the BIOS. With Intel AXX6DRV3G backplanes,
the BIOS hangs; with Intel AXX6DRV3GEXP backplanes, no drives
are detected in the BIOS utility.
