recommended. Doing so may result in unusual status updates,
such as Preparing to Dead to Ready.
4.5 ATAPI Devices
Adaptec Series 7 and Adaptec Series 8 controllers do not support
ATAPI CD-ROM, DVD, or tape devices.
4.6 System Compatibility Issues
o Discovery of Series 7 RAID controllers during system POST may be delayed
in some PCIe Gen 3 systems, if link-up errors occur during PCIe link
negotiation. These link-up errors occur rarely, are corrected automatically,
and pose no risk of performance or data integrity issues. If your system
is configured to log correctable PCIe errors you may see a small number of
errors recorded at the time of link training.
o With an Adaptec Series 7/8 controller connected to an ASUS P8Z77V-LK
motherboard, the controller may not be detected in slot 7.
WORKAROUND: Use slot 2 or slot 5.
o With an Adaptec Series 7/8 controller connected to an ASUS P8B-M
motherboard, the CTRL-A BIOS fails to load automatically after POST.
WORKAROUND: Press ENTER to load the BIOS during POST.
o Intel servers with BIOS version SDV.CP.B4.0 do not completely
clear popup messages when there are multiple popups in a
single operation in the uEFI/HII interface.
o With the HP StorageWorks D2700 enclosure, a maximum of 25 SAS
drives or 24 SATA drives are supported. Slot 0 cannot be used
with SATA drives.
o Promise J630 and J830 enclosures are not supported in this release.
4.7 Drive Compatibility Issues
o OCZ Vertex 4 SSDs are not supported in this release.
o With Seagate Constellation ES drives (eg, ST3500514NS) with
FW SN11, a medium error might result in SCSI command timeouts,
depending on the I/O load. This condition might be seen when
creating a logical drive with the 'build' initialization method.
o With Hitachi HUA721050KLA330 hard drives, the drive LED blinks
just once when using the CTRL-A BIOS 'Identify Drive' option.
The LED blinks continuously if blinked from ARCCONF or
maxView Storage Manager.
o With HP LTO-4 Ultrium 1840 tape drives, backup fails with Adaptec
Series 7 controllers.
WORKAROUND: Upgrade the drive firmware to A63D using an on-board
SAS or SATA controller, then try again.
o With Tandberg LTO-4 tape drives, backup fails during longer
write sequences with Adaptec Series 7 and Adaptec Series 8
controllers. The error is seen during writes in the 10GB-20GB
range, causing the operation to be aborted.
4.8 RAID 50/RAID 60, Max Drives
The maximum number of drives in a RAID 50 or RAID 60 differ
between maxView Storage Manager, ARCCONF, and the BIOS:
o BIOS and ARCCONF: 128 drives max
RAID 50 - From 2-16 legs with 3-32 drives/leg
RAID 60 - From 2-16 legs with 4-16 drives/leg
o maxView Storage Manager:
Assumes 2 legs for RAID 50/RAID 60 (non-selectable)
RAID 50 3-32 drives/leg (64 total)
RAID 60 4-16 drives/leg (32 total)
4.9 Solaris 32-bit Array Size Limits
Due to an OS limitation in Solaris 32-bit systems,
the practical limit for array size on Solaris 32
