a new machine. For more information, contact Adaptec Support. o New controller mode on Adaptec Series 7/8 controllers (ARCCONF/BIOS): - Simple Volume mode (limits RAID type to Simple Volume only) o Native support for 4K sector drives on Adaptec Series 7/8 controllers NOTES: (1) Only uEFI systems can boot from a 4K sector drive. 4K sector drives are not supported as a boot device with the Legacy (CTRL-A) Adaptec BIOS. (2) Support for 4KB logical sectors varies by vendor and OS version.

logical drive is >2TB, it is segmented into two partitions without warning, one up to 2TB, the other with the remaining disk space. Linux displays a pop-up message that the disk needs to be partitioned. o Before attempting to install an operating system in uEFI mode, you must delete all MBR partitions from the disk or reformat the disk with GPT. The installation may fail if you try to install on a disk with a MBR partitioning scheme. See also Section 4.11. 3.

Press CTRL+ALT+F7 to return to the installation screen and complete the installation. 3.8.2 SLES 11 SP3 with 4KB/Sector Drives 4KB/sector hard disk drives are not supported as a boot device with legacy (Ctrl-A) BIOS on SLES 11 SP3 (32-bit/64-bit). WORKAROUND: Install the driver in uEFI mode. Follow these steps (assuming you created a driver disk): 1. Boot from the SuSE installation DVD. 2.

Series 8Q/8ZQ controllers only. See the maxView Storage Manager Readme for maxCache Plus requirements and setup instructions. o The maximum number of SSDs that you can install on a controller for maxCache applications is: 8885Q/81605ZQ: up to 8 SSDs, with 2TB total capacity 7805Q/71605Q: up to 8 SSDs, with 2TB total capacity 6805Q/6805TQ: up to 8 SSDs, with 1TB total capacity See www.adaptec.com/compatibility for a list of maxCache-compatible SSD drives. 3.

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.

is 1TB. NOTE: If you create a >1TB array, OS tools, such as format or fdisk, won't detect them. 4.10 SLES 11 Boot Device Migration Issues By default, SuSE Linux uses the 'by-id' method to identify drives/partitions on the boot device. As a result, migration from one controller to another (eg, ASR-8885 to ASR-81605ZQ) fails because the original boot drive ID is not found on the new controller. WORKAROUND: Switch to the "by-uuid" method, then perform the migration.

NOTE: This behavior differs from previous releases (v1.05 and older), which supported other logical device types in Auto-Volume mode. 4.
