Hi, I have a machine with 3 x 9 gb scsi discs, Its a mylex controller. Here is my dmesg: mlx0: <Mylex version 4 RAID interface> mem 0xe3000000-0xe3001fff irq 10 at device 10.1 on pci0 mlx0: *** WARNING *** This firmware revision is not recommended mlx0: *** WARNING *** Use revision 4.06 or later mlx0: DAC960PG, 1 channel, firmware 4.04-0-00, 4MB RAM mlxd0: <Mylex System Drive> on mlx0 mlxd0: 8680MB (17776640 sectors) RAID 5 (offline) I know that there is 3 x 9 scsi discs on it but the config is set up as this, see above. But there is no bios on this card and I have to set up the array in w2k. I guess that? Any way I have installed a junk w2k installation for this so that, I can setup the array and the partion It in FreeBSD, As I only intend to run raid 0 on this tree discs. But Im woundering if there is any way of doing this in FreeBSD? Or I have to do it from w2k, I have not fixit it to work with my controller in w2k. Any way it is no an 100 % FreeBSD question. Im only woundering if it is possibel to do it in FreeBSD? With out w2k that is. In a other machine I have a AMI MegaRAID card and its working perfectly with 2 18,4 gb scsi discs. How ever I have get my hands on two extra 18,4 gb scsi discs and I want them to join the array. So Im woundering if there is any way of doing it from FreeBSD? Or I have to do it from w2k? So far I have not got very far yet, but I trying. I Have a w2k install on a junk disc. I think it should be possible to join 2 discs to an array. Here are some info from my array and card from dmesg: amr0: <AMI MegaRAID> port 0x9400-0x947f irq 2 at device 9.0 on pci0 amr0: <Series 428> Firmware UF82, BIOS 1.61, 32MB RAM amrd0: <MegaRAID logical drive> on amr0 amrd0: 35000MB (71680000 sectors) RAID 5 (degraded) And one last question why is my id 1 on cable one device getting degraded all the time when I reboot my system or have hade it shutdown for some time? I can provide more info if needed, It might have something to do with interferance or something smilare ? But I can have something to do what I did not have a clean shutdown? The last question is how do I avoid a device to not get degraded? Thanks for your time to read this email even if you don't answer it.
