time before those disk drives appear in Adaptec Storage Manager.
o With Intel Backplanes AXX4DRV3GEXP and AXX6DRV3GEXP, if a drive
bay is empty when the enclosure is powered up, 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 drive.
4.7 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.
4.8 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.
4.9 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.
4.10 OCE/RLM Limits and Restrictions
This release supports a maximum of 8 concurrent OCE tasks in
the RAID array migration wizard. The following RAID-Level
migrations (RLM) and Online Capacity Expansions (OCE) are NOT
supported:
o RAID 50 to RAID 5 RLM
o RAID 60 to RAID 6 RLM
o RAID 50 to RAID 60 OCE
4.11 Power Management under FreeBSD
The FreeBSD driver does not support power management in
this release.
4.12 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.
4.13 Power Management with Seagate SAS Drive ST31000640SS
