4.9 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
4.10 uEFI BIOS Issues
Using the "FW Update from Media" and "Save Support Archive"
commands in the same uEFI BIOS session may cause the system
to become unresponsive.
4.11 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.
4.12 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.
4.13 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.
