Question re doing upgrade repair of Vista

[pae77]

When I was "upgrading" Vista to repair a problem that was causing SP1 to fail to install (which worked btw), the compatibility check that Vista performs at the outset of the process listed one issue and that was "Storage Controllers, SCSI RAID Controller." I have no idea what that was about. I went ahead with the upgrade repair and everything appears fine. There are no problems evident by viewing device manager. Anyone know if this is something I should be concerned about or if there is anything else I should install to address this issue?

Thanks in advance.
