How can I detect if system has Software or hardware raid? Since in manual page:
The atacontrol command can also be used to create purely software RAID arrays in systems that do NOT have a "real" hardware RAID card such as a Highpoint or Promise card. A common scenario is a 1U server such as the HP DL320 G4 or G5. These servers contain a SATA controller that has 2 channels that can contain 2 disks per channel, but the servers are wired to only place a single SATA drive on each channel. Or how can I find out if the hardware is "real" hardware RAID card? For example my system has following dmesg output: ad4: 152627MB <Seagate ST3160815AS 4.AAB> at ata2-master SATA300 ad6: 152627MB <Seagate ST3160815AS 4.AAB> at ata3-master SATA300 ar0: 152625MB <Intel MatrixRAID RAID1> status: READY ar0: disk0 READY (master) using ad6 at ata3-master ar0: disk1 READY (mirror) using ad4 at ata2-master This system is an intel server with S3210SH server board in it. While installing system I see ad4,ad6 and ar0 as harddrives in sysinstall. I choose to install ar0. Additionally as far as I see ar0 is very susceptible to errors since a single CRC error can break the RAID consistency is that normal? I really appreciate those who uses such a kind of RAID1 Regards. _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
