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.
