3. Installation and Setup

   3.1 Installation Instructions

       The Adaptec SAS RAID Controllers Installation and User's Guide
       contains complete installation information for the controllers
       and drivers. The Adaptec RAID Controllers Command Line Utility
       User's Guide contains complete installation information for
       ARCCONF. The maxView Storage Manager User's Guide contains  
       complete installation information for the maxView Storage  
       Manager software.         
       
   3.2 Partition Setup
    
       o Logical drives with >2TB of storage require GPT partitioning
         (GUID Partition Table) for OS installation or use as a 
         data container.
         
         NOTE: Windows creates MBR partitions (Master Boot Record), by
         default, which can address only 2TB of storage space. If the
         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.
       
   3.3 DKMS Driver Setup for Red Hat 6/CentOS 6 
             
       Installation instructions for the pre-compiled DKMS drivers for
       Red Hat 6/CentOS 6 with Dynamic Kernel Module Support (DKMS) 
       are provided in the RAID Controllers Installation and User's Guide. 
       DKMS ensures that the driver remains installed across OS updates. 
       
       You can download the pre-compiled DKMS drivers for Red Hat 6
       and CentOS 6 at:
       
       http://ask.adaptec.com/app/answers/detail/a_id/17202
       
       NOTE: For DKMS driver instructions for other linux OSs, contact  
       Adaptec Support or check the Adaptec Support Knowledgebase (ASK)  
       at ask.adaptec.com. 

   3.4 AFM-700 Flash Backup Unit Setup
   
       3.4.1 Supercapacitor Setup with Adaptec Series 6Q Controllers
       
       Adaptec Series 6Q controllers do not include a mounting plate
       for the supercapacitor module. You must affix the supercapacitor 
       to the computer chassis with cable ties. For full instructions,   
       refer to the AFM-700 installation guide, available in the   
       documentation section of the Adaptec Web site at start.adaptec.com.
       
       NOTE: The user's guide describes how to install the supercapacitor
       using the mounting plate method. The instructions apply to Adaptec
       Series 7Q/8Q/8ZQ controllers and Adaptec Series 7/8 controllers
       with optional flash backup module only. 
       
       3.4.2 Status LEDs
       
       The AFM-700 Flash Backup Unit includes three LEDs to help you
       monitor status. See the labels on daughterboard PCB for LED 
       locations.
       
       LED 'DS2': Charger Enabled
       
       DS2 Solid on    Charger Enabled
       DS2 Blinks      Charger Off (during cap learn cycle)
       DS2 Temporary   No Supercapacitor attached
           Blinks
           
       LED 'DS3': Supercapacitor power indication; 
                  Supercapacitor charge Bleeding LED
                 
       LED 'DS4': Blinks faster when backup in progress
                
   3.5 Windows SBS 2011 Setup

       When installing the driver on Windows SBS 2011 Essential, the 
       installer times out before listing all discovered drives. The  
       number of listed drives varies, depending on the drive type (eg,  
       SAS vs SATA). This is a limitation in the Windows SBS installer; 
       the Adaptec device driver detects all attached drives.

   3.6 Solaris 11 Express Setup

       Installing Solaris 11/11.1 on a bootable array is not supported
       in this release.                           

   3.7 SLES 11 Setup

       3.7.1 SLES 11 SP3 Inbox Driver Issues

       With SLES 11 SP3 (32-bit/64-bit), the inbox driver takes 
       precedence over third-party drivers. As a result, the OS 
       loads the inbox driver rather than installing from
       the Adaptec driver disk.

       WORKAROUND: To avoid loading the inbox driver (assuming you 
       created a driver disk):

       1. Boot from the SuSE installation DVD. 
       2. Add 'brokenmodules=aacraid dud=1' to the boot menu. 
       3. Press the F6 key to update the driver during installation.
       4. Insert the USB driver disk.  
       5. On the 'Welcome screen', press CTRL+ALT+F2 to switch to the console,
          then type the following commands:
          # insmod ./update/000/modules/aacraid.ko 
          # rm -rf /etc/modprobe.d/blacklist /etc/modprobe.d/noload 
       6. Press CTRL+ALT+F7 to return to the installation screen and
          continue the installation. 
       7. When the installation is 60-90% complete, press CTRL+ALT+F2 to 
          switch back to the console, then type:     
          # cp -a /update/install /mnt/tmp     
       8. Press CTRL+ALT+F7 to return to the installation screen and  
          complete the installation.

       3.7.2 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. Add 'brokenmodules=aacraid dud=1' to the boot menu:
          o Change from: linuxefi /boot/x86_64/loader/linux
          o Change to:   linuxefi /boot/x86_64/loader/linux brokenmodules=aacraid dud=1
       3. Press F10 to boot.
       4. Insert the USB driver disk.
       5. Complete Steps 5-8 in Section 3.7.1 (above) to complete the installation.

   3.8 Fedora Linux Setup
  
       To avoid a known PCIe Active State Power Management issue under
       Fedora Linux 14, you must add the OS option `pcie_aspm=off` in
       the GRUB bootloader file "menu.lst". Follow these steps:
       
       1. When the first Fedora installation screen appears, press
          the 'Tab' key.           
       2. Before pressing the first 'reboot' button, edit grub/menu.lst:
          o Press Alt+F2
          o cd /mnt/sysimage/boot/grub/
          o Open the menu.lst file           
       3. Add 'pcie_aspm=off' just after 'rhgb quiet'. The new line
          should look like this:
          root (hd0,0)
          kernel /vmlinuz-2.6.33.3-85.fc13.i686.PAE... rhgb quiet pcie_aspm=off
          
   3.9 Debian Linux Setup
  
       After installing the Debian Linux driver, you must replace the 
       SCSI Device Partition Name in Debian’s GRUB bootloader with  
       a UUID. Failure to update the partition name may cause the   
       system to hang when the OS is rebooted. In the GRUB bootloader  
       file "menu.lst", replace the SCSI device partition name 
       (for instance, /dev/sda1), with UUID=<string>.

  3.10 Ubuntu Linux Setup
   
       o Due to a partition editor issue with Ubuntu 12.04.2, the OS
         reports an inaccurate drive size when creating a 4K sector
         boot drive in UEFI mode. As a result, the installer hangs  
         when creating the file system and the installation fails.
         
         WORKAROUND: Install Ubuntu 12.04.4 LTS (scheduled for release January 2014)

       o When installing the driver on an existing Ubuntu 11 or 12 OS, 
         the install script may stop at "grep vermagic" if the OS is 
         already installed with Ubuntu-desktop packages. To avoid this  
         problem, always install the driver packages first:
         
         # sudo dpkg -i aacraid-1.2.1-29600-Ubuntu11.04+11.10+12.04-all.deb

         ...then install Ubuntu desktop utilities by doing an online update: 

         # sudo apt-get install ubuntu-desktop

       o After installing the Ubuntu driver, you must increase the
         SCSI command timeout value from 30 seconds (the default 
         value) to 90 seconds. Failure to increase the timeout may  
         cause the system to hang with an EXT4 error when a good drive  
         is removed from a rebuilding array. Use these commands to   
         increase the timeout in SYSFS, assuming /dev/sda, /dev/sdb,  
         and /dev/sdc are the device LUNs on the Ubuntu Linux host:

         echo ``90``> /sys/block/sda/device/timeout
         echo ``90``> /sys/block /sdb/device/timeout
         echo ``90``> /sys/block/sdc/device/timeout                  
       
  3.11 Adaptec maxCache and maxCache Plus Setup
 
       o Adaptec maxCache is supported on Adaptec Series Q controllers
         only. maxCache Plus is supported on Adaptec 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.
       
  3.12 Dual Firmware Flash Image Support
   
       Adaptec Series 7 and Adaptec Series 8 controllers support 
       active and passive firmware images. Built-in logic determines
       the "right time" to update from passive to active, either at
       shutdown or boot up, and is designed to protect against image
       corruption or data loss due to power failure during image update.
       If the update occurs in the boot path, a server reboot is 
       expected. Additionally, you must be running the latest drivers.
     
       NOTE: This feature is enabled only when upgrading from and to 
       a firmware version that supports dual firmware images. For 
       customers upgrading from an Adaptec release prior May 2013 
       (specifically, Firmware Version 7.2.0, Build 30260), there 
       is no change in behavior. The firmware image is updated in 
       one stage.        

  3.13 Adaptec Flash Utility (AFU) Support
   
       Adaptec Series 8 controllers do not support the DOS-based
       Adaptec Flash Utility (described in the user's guide). To
       flash a Series 8 controller, use the uEFI BIOS, ARCCONF,
       maxView Storage Manager, or the maxView Storage Manager 
       bootable USB image.
     
--------------------------------------------------------------------
4. Known Limitations

   4.1 Linux Boot Device 
   
       Regardless of which device you select to install the OS, the
       boot record is always written to Device 0. As a result, 
       Linux will fail to boot if you delete or swap away Device 0.
       For example, if you create three arrays in the BIOS--VOL-0,
       VOL-1, and VOL-2--install the OS on VOL-1, then swap VOL-0 
       and VOL-2, Linux will fail to boot. Restore the original
       array sequence and Linux boots normally. Ideally, you should
       always install on Device 0.   
        
   4.2 OS Installation with RAW Devices

       With Adaptec Series 7 and Adaptec Series 8 controllers, installing
       the OS in a mixed configuration with RAID Arrays and RAW devices 
       is not supported.

       WORKAROUND: Remove the RAW devices, install the OS on the RAID  
       array, then re-install the RAW devices.

   4.3 Adaptec Series 6 Controller Issues
             
       The following issues are seen only with Adaptec Series 6 RAID
       controllers:

       o The Adaptec Series 6 controller driver does not implement 
         the PCI suspend/resume function to support Linux Kernel Power
         Management.              
              	        
       o Due to a PCIe configuration problem with ASUS Z9PE-D8 WS 
         motherboards, Adaptec Series 6 controllers are not detected 
         in slots with x8 links (eg, slots, 2,4,6). 
             
         WORKAROUND: Use a slot with x16 links.
      
       o Hybrid RAID 10 logical drives (comprised of an equal number 
         of SSDs and HDDs) are not built correctly in the CTRL-A BIOS;
         the segment order is incorrect. 
      
         WORKAROUND: Create the Hybrid RAID 10 in maxView Storage Manager or ARCCONF.
   
   4.4 AFM-700 Flash Backup Unit
  
       Hot-plugging the AFM-700 supercapacitor module is not 
       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 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. 
       
   4.7 System Compatibility Issues

       Promise J630 and J830 enclosures are not supported in this release.
       
   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 
       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.

       Step #1:  Use the blkid command (built-in utility) to find the UUIDs of file systems  

       sles11sp1boot:~ # blkid
       /dev/sda1: UUID="4512cf7d-4e22-4dfa-8991-4084dae41409" TYPE="swap" 
       /dev/sda2: UUID="b144a0a2-b7fc-47fd-8459-ba40d0f663cd" TYPE="ext3"

       Step #2:

       (a)  cd /etc
       (b)  edit fstab file
       (c)  Change the "by-id" names of file systems to their corresponding "uuid" names found in Step #1

       Note:  Make a backup of the fstab file before modifying it.

       Step #3:

       (a)  cd /boot/grub
       (b)  edit menu.lst file 
       (c)  Change the "by-id" names of file systems to their corresponding "uuid" names found in Step #1

       Note:  Make a backup of the menu.lst file before modifying it.

       Step #4:

       (a)  Shutdown the SUSE system 
       (b)  Change the HBA/controller
       (c)  Boot the system

  4.11 uEFI BIOS Issues
  
       o Using the "FW Update from Media" command and "Save Support 
         Archive" in the same uEFI BIOS session may cause the system 
         to become unresponsive.
       
       o uEFI-mode setup is not supported on Supermicro X9SCL-LN4F 
         and X9DRi-F motherboards.

  4.12 BIOS Feature Disparity: Selectable Performance Mode
  
       In the Legacy (CTRL-A) BIOS, the Selectable Performance Mode  
       option is enabled for controllers operating in HBA Mode. This
       differs from maxView Storage Manager and ARCCONF, which disable  
       Selectable Performance Mode if the controller is in HBA Mode.

  4.13 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.

  4.14 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.
