That is interesting. Thanks for the info... However...
The really interesting thing is that the lu itself is the s2 inside the
solaris partition... So it's not the whole disk...
sudo mpathadm list lu
/dev/rdsk/c0t5000C5003424396Bd0s2
Total Path Count: 1
Operational Path Count: 1
/dev/rdsk/c0t5000C5002637311Fd0s2
Total Path Count: 1
Operational Path Count: 1
So again, for clarity:
I installed sol11e, and during installation, opted to use a partition of the
hard drive instead of whole drive. End result is the fdisk partition
occupies 5% of the disk, and inside it, there is the solaris partition
slices, s2 occupies 100% of the 5% fdisk partition. I want to replicate
this config onto the 2nd disk identically for the purposes of mirroring.
Since the multipath device $foo (c0t5000C5003424396Bd0s2) is itself just
inside the fdisk partition, it means I can't use that device to replicate
the fdisk partition. I'll have to somehow figure out which d0 device $bar
(/dev/rdsk/c0t600C0FF000000000092C4D22A708D800d0) correlates to the first
disk versus the second disk.
I guess I'll just have to remove the 2nd disk, see which one disappears, and
go from there.
