Sharing a physical disk with an LDOM
I have a guest LDOM running Solaris 10U11 on a Sun T4-1 host running Solaris 11.4. The host has a disk named bkpool that I'd like to share with the LDOM so both can read and write it. The host is hemlock, the guest is sol10.
Code:
root@hemlock:~# zpool list
NAME    SIZE  ALLOC  FREE  CAP  DEDUP  HEALTH  ALTROOT
bkpool  832G   253G  579G  30%  1.00x  ONLINE  -
rpool   832G   666G  166G  80%  1.00x  ONLINE  -

I followed the directions here Using Virtual Disks With Logical Domains but they didn't work.
Code:
root@hemlock:~# ldm add-vdsdev /dev/dsk/c0t5000C50070FFBF07d0s2 vdiskbk@primary-vds0 
root@hemlock:~# ldm add-vdisk vdskbk1 vdiskbk@primary-vds0 sol10 root@hemlock:~#

The disk is question is disk 0:
Code:
root@hemlock:~# format
Searching for disks...done

AVAILABLE DISK SELECTIONS:
       0. c0t5000C50070FFBF07d0 <SEAGATE-ST900MM0006-0001-838.36GB>
          /scsi_vhci/disk@g5000c50070ffbf07
          /dev/chassis/SYS/HDD2/disk
       1. c1t3A0D19F2BE2346CEd0 <LSI-Logical Volume-3000-837.26GB>
          /pci@400/pci@1/pci@0/pci@4/scsi@0/iport@v0/disk@w3a0d19f2be2346ce,0

I stopped and restarted the LDOM, but there is no sign of /bkpool there.
Code:
# ls /dev/dsk
c0d0s0  c0d0s3  c0d0s6  c0d1s1  c0d1s4  c0d1s7  c0d2s1  c0d2s4
c0d0s1  c0d0s4  c0d0s7  c0d1s2  c0d1s5  c0d2    c0d2s2  c0d2s5
c0d0s2  c0d0s5  c0d1s0  c0d1s3  c0d1s6  c0d2s0  c0d2s3  c0d2s6
# zpool list
NAME   SIZE  ALLOC  FREE  CAP  HEALTH  ALTROOT
rpool  596G  10.0G  586G   1%  ONLINE  -
#

But according to the host, the disk is there
Code:
root@hemlock:~# ldm list-services
VCC
    NAME         LDOM         PORT-RANGE
    primary-vcc0 primary      5000-5100

VSW
    NAME         LDOM         MACADDRESS          NET-DEV   DVID|PVID|VIDs
    ----         ----         ----------          -------   --------------
    primary-vsw0 primary      xx:xx:xx:xx:xx:xx   net1      1|1|--       

VDS
    NAME         LDOM         VOLUME         OPTIONS          MPGROUP        DEVICE
    primary-vds0 primary      vol1                                           /sol10dsk
                              voliso         ro                              /export/home/michele/Downloads/sol-10-u11-ga-sparc-dvd.iso
                              vdiskbk                                        /dev/dsk/c0t5000C50070FFBF07d0s2

I'm stuck. What am I doing wrong?

UPDATE:

Actually it seems like the guest does know about the bkpool disk:
Code:
# format
Searching for disks...done

AVAILABLE DISK SELECTIONS:
       0. c0d1 <SUN-DiskImage-600GB cyl 17064 alt 2 hd 96 sec 768>
          /virtual-devices@100/channel-devices@200/disk@1
       1. c0d2 <SEAGATE-ST900MM0006-0001-838.36GB>
          /virtual-devices@100/channel-devices@200/disk@2

So I guess now the question is simply how do I make c0d2 available in the Solaris 10 LDOM? I'd like the final result to be that the LDOM contains a mountpoint named /bkpool that holds the contents of the disk.
