3Ware 9000 Series Release Notes page 6

3. Use 3DM 2 or tw_cli to rescan the controller. The new unit capacity will now
available to the operating system.
4. Filesystem resizing is not automatic. Use the appropriate Linux tool to resize or
grow the filesystem. Check the manual pages for more details about resize_reiserfs,
xfs_grow, resize2fs, etc. Some filesystems cannot be resized at all. Others can
only be resized when off-line or unmounted.
SuSE Errata
• "LUN larger than current supported" errors under SuSE 9.2 and 9.0ES
o These errors may occur on systems with memory over 4 GB
• Out of memory errors under SuSE 9.2
o Memory errors may occur when running even a minimum amount of
I/O, on systems with 2 GB or more RAM.
• Kernel does not detect a new array created from 3ware BIOS, except for boot
device.
o As a work around use 3DM 2 or tw_cli to remove the unit and rescan the
controller or execute the command:
/etc/rc.d/boot.udev force-reload
• Boot fails after installing SuSE 9.0ES
o SuSE 9.0ES and earlier installers contain a bug that does not update
initrd to include the 3w-9xxx drivers. This has been fixed in SuSE 9.2.
The work around is to run the installation normally as described in the
Installation Guide, but at the end when SuSE displays the "Now booting
your system" countdown, immediately click the stop button and switch
over to the console by using the Ctrl+Alt+F2 key combination on the
keyboard. Change directories to /update/000/install and run the update
script which will copy the necessary 3ware driver and update initrd
accordingly. When the update is completed, return to the install screen
with Ctrl+Alt+F7 and click the OK button to finish the installation.
Linux (all versions) and usage of Ctrl+c
The use of Ctrl+c to abort operations is not recommended while having I/O to the
3ware controller. The following are know incompatibilities:
1. Create a RAID-0 unit
2. Migrate the unit to another RAID-0 using CLI
3. Format and perform I/O on the array
4. Delete the unit using CLI
5. Hitting Ctrl+c causes a kernel panic
3BM BIOS is enabled or disabled for all controllers
Pressing Alt+B every time you boot when the 3ware BIOS is displayed during boot will
disable the BIOS for all 3ware controllers in the system.
