Hi,
After seeing the undeadly article I got myself a Sun T1000 and have
been playing with ldoms on it. I saw a few things:
1. Partitions cannot be used as backing store for ldom virtual disks,
the VOP_GEATTR calls return size 0 for the raw device. I also wonder
if other VOP call in vdsp(4) will work without a filesystem.
2. If I halt(8) the primary with -p, it actually reboots after the
shutdown. Just a halt gets me an ok prompt.
3. In ALOM, doing a poweroff -f works as expected: it does an
immediate power cut. But a poweroff without -f resets the (halted)
primary first so it starts to boot and then there is a delay before
the actual power cut. The delay is long enough so the primary gets to
mount filesystems. But at that point the power is actually cut off,
leaving dirty filesystems. I suppose the ALOM poweroff without -f
should shutdown the host, but it actully seems to do a reset.
But apart from this, the ldoms work really nice ;-) Of course there's
a ton of 'would be nice to have' things, but it is very useable
already.
