    hi all-

    i’ve been working on my first xserve installs this week. it’s been interesting, for sure, setting up headless servers apple-style. i have two boxes and time to play with them, so i’ve installed, setup, and blown away the systems remotely a few times, using the CLI as well as the server assistant, just to get a feel for the options.

    in any case, i’ve decided the “best practices install” guide here is the best guide to where i want to go with these, so i’ve followed it and the other disk imaging writeups, with the intention of imaging a base install before configuration.

    but after installing my HW raid cards and extra disks (3x80G in each), RAID5ing my drives (5 30Gvols each), formatting the volumes, and completing the base install, the RAIDed drives don’t mount to my admin system when booted in target disk mode. the installer CD *does* mount to the target system, when inserted into the xserve drive.

    i know the xserves themselves are happy with the RAID volumes- i completed the setup on one box, and it runs in standalone mode just fine, server admin shows a happy server. the other system is a virgin install, but shows up in sa_srchr as RDY4Setup.

    the installs seem fine, it just seems like target disk mode doesn’t get the RAID going.

    any suggestions? this seems to me like a show-stopper as far as far as imaging HWRAIDed boot volumes, but that process seems like pretty well-trod ground around here- what am i missing?

    thanks in advance-

    You are correct in that the HW RAID card will not show up in target disk mode.

    Boot from the CD, ssh in, create the RAID set and volumes. Then use either ASR, or diskutil to pull the diskimage across the network to the volume you want to image it to.

    A little more complicated but not much.

    ok, was out sick all last week, this post was the last thing i managed to do before hitting the dirt.

    thanks for the confirmation, i’ll tinker around more this afternoon. at the moment i can’t quite visualize how to push the image across the network before i’ve set up networking…

    i’ve got other local volumes i can write the image to temporarily if need be, so it’s no big deal. it’s bugging me that i can’t picture this, though.

    i’lll get on it after i slog through my mail backlog-

    thanks again!
