OK, I'm glad I asked then. So I have to mount the /bkpool disk in the LDOM as an NFS share? Can you give me a pointer on how to do that? Is this what Oracle calls "virtual disk multipathing"? There's an example of that further down in the link in the OP but I'm not quite sure how to do it. Also, do I first need to undo the add-vdsdev and add-vdisk commands I gave earlier? I don't want to mess up my disk.

UPDATE

Well as usual the Oracle documentation was overly complex and ambiguous. I figured it out, thanks to the suggestion above:

On the host, assuming the IP of the LDOM at 192.168.0.78, do:

Code:

root@hemlock:/# share -F nfs -o rw,root=192.168.0.78 /bkpool/

Then in the LDOM (with the IP of the host hemlock at 192.168.0.183), do:

Code:

# cd /
# mkdir bkpool
# mount -F nfs -o vers=3 192.168.0.183:/bkpool /bkpool

The LDOM now has a mountpoint named /bkpool containing everything on the host's /bkpool disk. The host and the LDOM can both read and write the disk. No rebooting anywhere required. Easy! :-)

tgt-setup-lun(8)					      System Manager's Manual						  tgt-setup-lun(8)

NAME

       tgt-setup-lun - creates a target, adds a device to the target and defines initiators that can connect to the target

SYNOPSIS

       tgt-setup-lun -d device -n target_name [initiator_IP1 initiator_IP2 ...] [-h]

DESCRIPTION

       Starts tgtd if necessary and creates a target according to the supplied target_name. The format of the target name is as follows:
       iqn.2001-04.com.<hostname>-<target_name> The target name must be unique.

       The  script then adds the requested device to the target. If specific IP addresses are defined, it adds them to the list of allowed initia-
       tors for that target. If no IP addresses is defined, it defines that the target accepts any initiator.

EXAMPLES

       Create a target that uses /dev/sdb1 and allows connections only from 192.168.10.81:
       tgt-setup-lun -d /dev/sdb1 -n my_target 192.168.10.81

       Create a target that uses /dev/sdb1 and allows connections only from 192.168.10.81 and 192.168.10.82:
       tgt-setup-lun -d /dev/sdb1 -n my_target 192.168.10.81 192.168.10.82

       Create a target that uses /dev/sdb1 and allows connections from any initiator:
       tgt-setup-lun -d /dev/sdb1 -n my_target

       Display help:
       tgt-setup-lun -h
