Howdy all,
I've decided to give Sun's qlc drivers a shot and have run into a
quandry. I have assigned a LUN from a 6130 to a V120 with a Dual Port
2GB FC HBA (seperate fabric paths per port) and set mpxio-disable="no";
in /kernel/drv/scsi_vhci.conf. I patched the system fully (smpatch/patch
cluster/PatchPro Hub for Storage Devices). Rebooted. Ran cfgadm -c
configure c3 c4. However when I look at luxadm display of the two disk
devices I see there are two paths (one through each port) but there is
no scsi_vhci device path as all the documentation refers to... See
below:

So, perhaps this is normal and I'm confused, or perhaps I'm missing
something. I was under the impression that a single scsi_vhci device
would be created for both disk devices since they are actually the same
LUN. Can anyone shed some light?
On a side note, after installing the data host software and trying to
run ras_install for StorADE, it complains that the version of perl that
comes with Solaris 9 and my copy of Perl 5.8 are not supported for the
ras_install, but it doesn't say what a supported version is. This really
isn't as critical as the above issue, but if you know of the answer, let
me know.
