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.
