Operating System Support

Please note the following:
•
You cannot delete a logical drive during a reconstruction. Also, you
cannot delete a logical drive during a rebuild, initialization, or check
consistency of a logical drive, if that drive has a higher logical drive
number than the drive you want to delete. You must wait until these
processes have completed before deleting the logical drive.
•
Drive size extension is not possible, even though you can use non-
contiguous free space to create a new logical drive.
•
You cannot move an existing logical drive to another area to protect
it from defragmentation caused by random deletion.
The MegaRAID Configuration Software User's Guide has detailed
procedures for deleting logical drives.
Background initialization is a process to correct parity on the virtual disks.
It ensures that striped data segments are the same on all physical disks
in a disk array.
The background initialization rate is controlled by the background
initialization rate set using your array management software. You must
stop an ongoing background initialization before you change the rate, or
the rate change will not take effect. After you stop background
initialization and change the rate, the rate change will take effect when
you restart background initialization.
Note: Unlike initialization of virtual disks, background initialization
does not clear data from the physical disks.
The MegaRAID Serial ATA storage adapters support several major
operating systems. LSI Logic provides device drivers and RAID
management tools for operating systems on the Universal Driver Suite
CD that accompanies the SATA boards.
You can download the latest drivers and software from the download
center on the LSI Logic web site at
http://www.lsilogic.com/cm/DownloadSearch.do. Follow the steps to
download the driver.
