I found this.... and as they say.. I cannot Megaraid_mbox does not support my type of hardware anymore.. I deploy the information for everyone who wants to know..
The kernel shipped with Red Hat Enterprise Linux 4 (in this case Fedora 5) includes the new
megaraid_mbox driver from LSI Logic, which replaces the megaraid driver.
The megaraid_mbox driver has an improved design, is compatible with the
2.6 kernel, and includes support for the latest hardware. However,
megaraid_mbox does not support some of the older hardware that was
supported by the megaraid driver.
Adapters with the following PCI vendor ID and device ID pairs are not
supported by the megaraid_mbox driver:
The lspci -n command can be used to display the IDs for adapters
installed in a particular machine. Products with these IDs are known by
(but not limited to) the following model names:
* Dell PERC (dual-channel fast/wide SCSI) RAID controller
* Dell PERC2/SC (single-channel Ultra SCSI) RAID controller
* Dell PERC2/DC (dual-channel Ultra SCSI) RAID controller
* Dell CERC (four-channel ATA/100) RAID controller
* MegaRAID 428
* MegaRAID 466
* MegaRAID Express 500
* HP NetRAID 3Si and 1M
Both Dell and LSI Logic have indicated that they no longer support these
models in the 2.6 kernel. As a result, these adapters are not supported
in Red Hat Enterprise Linux 4.
and advise if your megaraid controller is one of these listed - I may be
able to point you to a work around.
