Big LUN's?
I have 3 RAID 5's initializing now - they've been at it about 8 hours.
I'm expecting ach of these RAID 5's to add amount to 3.2 terabytes.
I heard that both Solaris 9 and Solaris 10 (to be fixed in Solaris 10 update 2) have problems with LUN's over 2 terabytes.
Does that mean that I'm either going to have to decrease the capacity of the RAID 5's, or perhaps add all these RAID 5's together into an LVM on the 3511 and then carve up that LVM into a bunch of smaller Logical Disks to be mapped to LUN's individually?
I called Sun tech support about this, and they suggested just trying it, which is something my management has signed off on, so that's probably what I'll be trying first....
Thanks!

Someone on comp.unix.solaris indicated that LUN's above 2 Terabytes are
just not going to work, and suggested partitioning the logical drives.
However, when I attempt to to do this, I'm getting:
smft1-root sbin) ./sccli /dev/es/ses0 show partitions
sccli: selected device /dev/es/ses0 [SUN StorEdge 3511 SN#09203A]

esmft1-root sbin) ./sccli /dev/es/ses0 configure partition 1E7C869C-01 1714421MB
sccli: selected device /dev/es/ses0 [SUN StorEdge 3511 SN#09203A]
sccli: not enough space available from previous partition
Any suggestions? Is it possible that the initial partition sizes of 0MB
are the problem? And if so, what alternatives do we have?
Thanks!
