disklabel sd1 | grep label For sd1 and sd2 please. This is what is printed in installer. See diskinfo() in src/distrib/miniroot/install.sub If it does print just 'iSCSI Storage 3.1' then this is not very useful info in the installer (although one can break and investigate dmesg) So maybe disklabel should have better 'label' or we could print more info directly in the installer. I'm also not sure sysctl hw.disknames output is best one, it does show duid which is OpenBSD specific (compare disklabel with and without '-d'). It seems there's no good solution fitting all cases (softraid, usb disks, both are scsi-like devices). j.
