My testing env is Vmware, the backend disks are new/empty.
Here's my testing result:
1. OpenBSD 4.1 with iscsi-target compiled (I can't find it in the
ports)
It support disk slice directly, I use /dev/sd1c.
2. NetBSD 4.0-current with iscsi-target in base OS
It support disk slice directly, I use /dev/sd1d.
3. FreeBSD 6.2 with iscsi-target port:
When the new harddisk is added. It is empty and do not have any
individual slice (only have /dev/da1).
iscsi-target cannot use /dev/da1 directly (tested yesterday)
/dev/da1c is gone in FreeBSD (since 5.0)....
I have tried to create a disk slice by fdisk (/dev/da1s1 and
/dev/da1s1c is created).
But iscsi-target cannot use them directly:
