I'm not sure about this. If you're using software RAID, the RAID kernel (and whaever driver works for your SCSI controller) is all that's required. Probably, the Compaq SmartArray controller requires a special driver, and takes care of the raid issues itself. If so, if the driver is part of the normal kernel tree, you should simply be able to load support for it like any other SCSI card, and access any RAID partitions the card is configured for. See my Hard-Disk-HOWTO for details on adding SCSI support at runtime (besides the driver for the SCSI card, you need to load the 3 or so modules that add SCSI support to the kernel). The worst case is if your card is one of the funky "hybrid" raid cards. Kind of like "winmodems", these cards provide hardware acceleration for the RAID functions, but require OS drivers to actually talk to the RAID device properly. If your card is one of these (I don't know about the compaq card, but most of the Adaptec "raid-port" cards fall into this catagory), you're probably not looking at a good chance for success, unless you're already running linux on the system, in which case you can probably track down drivers somewhere for making a boot/rescue disk. NOTE: A quick search on the compaq site turns up the cpqarray driver page on SF, which is apparently a driver for this controller: http://sourceforge.net/projects/cpqarray/ Charles Steinkuehler http://lrp.steinkuehler.net http://c0wz.steinkuehler.net (lrp.c0wz.com mirror) _______________________________________________ Leaf-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/leaf-user
