[OmniOS-discuss] 2x acctual disk quantity

[Hafiz Rafibeyli]

Saso ,I will try edit /kernel/drv/scsi_vhci.conf as you described and will inform you.

why these new disks not dedected by scsi_vhci automatically?

is this because of settings in my /kernel/drv/mpt.conf and /kernel/drv/mpt_sas.conf files?

Ok, so in regards to multipath, looking at format(1) I can see that
scsi_vhci doesn't have your drives whitelisted for multipath support, so
that's why you're seeing lines such as:

      14. c4t5000C5002BD75C05d0 <HP-EG0300FAWHV-HPDE-279.40GB>

/pci at 0,0/pci8086,340e at 7/pci15d9,400 at 0/iport at f/disk at w5000c5002bd75c05,0

in format(1) output. If scsi_vhci had detected your disks, the paths
would start with "/scsi_vhci..." rather than "/pci...". No problem, you
can manually whitelist the disks (here's the full manual):
http://docs.oracle.com/cd/E19253-01/816-5177/6mbbc4gal/index.html

In principle what you need to do is add a line like this:

device-type-scsi-options-list =
   "HP      EG0300FAWHV", "f_sym";

Please note that there are 6 spaces following 'HP' in the above
identifier - copy it exactly as it appears here (scsi_vhci needs the
vendor ID to be exactly 8 characters long, so we need to pad it with
spaces). After you've done this you should be able to reload the driver
configuration (via "update_drv scsi_vhci"), your drives should reappear
in the "/scsi_vhci..." device path with the correct number (4 drives,
not 8) and "mpathadm list lu" should display them and the paths to them.
If update_drv is going to be giving you trouble, a reboot might be
needed (haven't tested this in a while, so I don't remember).

You can double-check the Vendor ID and Product ID that you need to enter
in there by running "prtconf -v" and looking for the drive in the device
tree. You should be able to see lines like these:

                name='inquiry-product-id' type=string items=1
                    value='EG0300FAWHV'
                name='inquiry-vendor-id' type=string items=1
                    value='HP'

Cheers,
