Some bits from the in-house documentation I've been writing. I've tested this on multiple occasions on my 1U Supermicro SATA boxes, so might possibly be interesting for someone. * RAID setup: (If required, FreeBSD only) - ensure that the drives are probed as ad4 and ad6 like: ad4: 76324MB [155072/16/63] at ata2-master SATA150 ad6: 76324MB [155072/16/63] at ata3-master SATA150 - if they do not probe correctly, check the BIOS settings above - perform a minimal install of FreeBSD 5.3 (do not worry about network or anything) - reboot from the installed OS and login as root - Run the command "atacontrol create RAID1 ad4 ad6" to create the raid set - Reboot and reinstall the OS, choosing ar0 as the drive, which should probe like: ad4: 76324MB [155072/16/63] at ata2-master SATA150 ad6: 76324MB [155072/16/63] at ata3-master SATA150 ar0: 76324MB [9730/255/63] status: READY subdisks: disk0 READY on ad4 at ata2-master disk1 READY on ad6 at ata3-master Minimal Survival for FreeBSD software RAID1 sets * Read the atacontrol man page * atacontrol status ar0 - to check the status * atacontrol detach 2 - to detach ad4 if failed (again, use 3 for ad6). The SATA disks in the 5013C-T chassis are hotswappable, so it can be pulled once detached. * atacontrol attach 2 - to reattach ad4 once replaced * atacontrol addspare ar0 ad4 - to add the replaced ad4 as a spare on the RAID set * atacontrol rebuild ar0 - to rebuild the mirror -- Jon Simola Systems Administrator ABC Communications _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "[EMAIL PROTECTED]"
