Trying to get Solaris 10u6 on an HP DL185 can be thought of as an adventure to put it mildly.
Here is a brief idea of the steps that are needed. I'll add more detail as I have time.
1. Get the 10u5 miniroot.
2. Unpack the miniroot and install the Disk Array drivers into the miniroot.
3. Use that miniroot to PXE boot the 10u6 install.
4. Do the install ( I like using the flar install ).
5. During the install, tell it to NOT automatically reboot.
6. When it is finished with the install, drop into a shell.
7. You need to install the HP drivers package. You can bring up the network to install it, copy it off CD, or get it some other way.
8. Reboot the box.
9. When it gets to the grub prompt, Edit the entry and add a -r on to the end to tell it to reconfigure it's devices.
10. Chances are it won't boot correctly and will have it's filesystem read only.
11. Check it's disk numbering and you may find that it went from c0t0d0 to c1t0d0.
12. If it did, adjust /etc/vfstab and reboot.
Update: I made a flar of the finished product and it installs much easier. It doesn't reorder the disk, controllers, etc.
