User`s guide

NOTE: This behavior differs from previous releases (v1.05 and older),

which supported other logical device types in Auto-Volume mode.

4.15 Cache Preservation Issues

o Documentation note: the following errata clarifies and supercedes

the description in the user's guide:

"With cache preservation enabled, the system preserves the

controller's DDR cache to prevent data loss in the event of

(1) a power failure or unsafe shutdown of external enclosures

while the host system, with the controller, still has power;

and (2) connectivity problems with drives."

o In this release, creating a RAID 0 with a 16K or 32K stripe

size is not supported if cache preservation is enabled.

4.16 Force Rebuild in CTRL-A/uEFI BIOS

With Automatic Failover disabled, Force Rebuild in the CTRL-A

(Legacy) BIOS fails if you insert a new drive in place of a

pulled member drive. (The logical drive rebuilds successfully

when the same member drive is pulled and reinserted.) In the

uEFI BIOS, Force Rebuild fails in both cases: inserting the

pulled member drive or inserting a new drive.

4.17 Linux Power Management Support

The Adaptec Series 6/7/8 controller driver does not implement

the PCI suspend/resume function to support Linux Kernel

Power Management.

4.18 hdparm Support

On Windows and Linux, the 'hdparm -i' command, used to set and

view ATA hard disk drive hardware parameters, is not supported

for direct-attached drives on Adaptec SAS controllers. Since

'hdparm -i' is designed for native libata/ide drivers,

the command is working as designed and the behavior is expected.

WORKAROUND: Use the 'hdparm -I' command instead.

4.19 HDA Mode Reset

Adaptec Series 7 and Adaptec Series 8 controllers are reset

using the HDA mode jumper on the controller board. If a HDA

reset is required, contact Adaptec Support for assistance.
