Hi all,

I have a Sun Server (220r) and I will have to make it boot on FC.
Can you help ?
I'm looking for information : is it possible ? howto ? documentation about
that.

Is there any constraints/config if I want to use VxVM ?

Thanks a lot for help,
Best regards,

Philippe Rodriguez

You can't use VxVM, clear and simple. The OBP only understands UFS.
You can encapsulate the root volume, but the filesystem underneath must
be UFS. Turn on logging if you need VxVM features like quick fsck on
reboot.

VxVM does not imply VxFS

Yes, my mistake. Brain stuck in "VxVM == VxFS", even though I typed it
several times. Using VxVM still _may_ imply some sort of RAID, which is
also not allowed by the the OBP. Solaris can boot an encapsulated root
volume, but not a RAID<anything> unless it's hardware RAID.

It is possible to boot from a mirrored (RAID-1) root partition using
UFS filesystems and VxVM, using non-hardware RAID.

Yes, if it's encapsulated. If you create a volume from two plexes, then
put the OS on them, I don't think you'll be able to boot from that
configuration. I think the OPB needs a slice that's got a bootblock and
creating an encapsulated root drive will do that. Then you can mirror
it with another drive. I sort of think of this as a special case of
mirroring because other volumes aren't mirrored in the same way.

OpenBoot understands nothing about UFS, it only understands the disk
labels to find partitions. the UFS code is in the bootblock on the
disk and is not part of OpenBoot.

fc-loop or fc-fabric?

It has to be encapsulated but there was a bug with vxvm and fabric boot.
