https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=212211 --- Comment #14 from Terry Kennedy <terry-freebsd@glaver.org> --- Created attachment 229667 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=229667&action=edit Requested info I'm attaching the output from the two commands you requested. /dev/da0 is a RAID5 of 4 SSDs. This is a PERC H730 (PCI card=0x1f491028 chip=0x005d1000) in a Dell PowerEdge R730. There seems to be partial support for passthru in the mrsas driver. I think I noted this in my first comment on this PR. There is quite a large amount of variation in the behavior of the various MegaRAID drivers in FreeBSD. mfi will expose all of the physical member disks as /dev/passX devices if the undocumented mfip module is loaded. One of the other MegaRAID drivers (mpr, maybe?) has an interesting misfeature of only exposing the last physical member disk of a volume as a /dev/passX device. -- You are receiving this mail because: You are the assignee for the bug.home | help
