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.
I followed the directions here Using Virtual Disks With Logical Domains but they didn't work.
The disk is question is disk 0:
I stopped and restarted the LDOM, but there is no sign of /bkpool there.
But according to the host, the disk is there
I'm stuck. What am I doing wrong?
UPDATE:
Actually it seems like the guest does know about the bkpool disk:
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.

One thing for sure is that only one of the nodes (Solaris 11 Global or Solaris 10 LDOM) can have control of the volume. In any situation, having two operating systems writing to a volume simultaneously is a recipe for instant filesystem corruption. One operating system must control file opening, locking, etc. Even in a cluster scenario using dual tailed storage, a major function of the cluster suite is to control which node has exclusive control of the volume and effect disciplined failover when necessary.
Therefore, like any two nodes, one option is to mount the volume on one node, configure a NFS share on that node, and mount the volume using a NFS client from the second node. The first node then controls ALL activity on the volume.

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

Hi! Quick background for the question...
I have Solaris 11.4 control/primary zone with some LDOM's on top of it. I have some raw iSCSI LUN's presented to the control zone/primary zone from a NetApp, which I then pass up to the LDOM's via the VDS/vdisk. So basically the LDOM VM's see the disk as... (1 Reply)
Generally, this is what we do:-
On primary, export 2 LUNs (add-vdsdev).
On primary, assign these disks to the ldom in question (add-vdisk).
On ldom, created mirrored zpool from these two disks.
On one server (which is older) we have:-
On primary, create mirrored zpool from the two LUNs.... (4 Replies)
Hi,
There is LDOM Guest where I need to expand /u02 file systems on it.
It is residing on a Solaris 11 Hypervisor (Primary Domain).
The storage is expanded on vdisk presented to Hypervisor.
I need steps to expand the /u02 on LDOM Guest. (2 Replies)
Hi ,
I had a requirement to share a san disk between two rhel severs. I am planning to discover the same disk in two rhel nodes and mount it. Is it a feasible solution? and what kind of issues we may encounter mounting same disk in two OS's parallel ? (2 Replies)
I have viewed a few previous posts regarding this, but none of them quite described or worked with my issue.
I am out of local disk space on my LDOM Manager but still have plenty of SAN vCPU and Memory available so I am trying to install a new LDOM OS on SAN.
I have exposed the SAN to the... (0 Replies)

Hello,
I have a SUN T5240 running Solaris 10 with Logical Domain Manager (v 1.0.3). You can use the "ldm" command to display current resources on the box. Is there away to display all the "physical resources" on the box(i.e.,used and unused). For example, "ldm ls" will tell me what the... (5 Replies)
Hi
is there a cmd in hpux 11 to determine the physical size of the hard disk.
not bdf command.
i have searched the other threads here but cant find an answer.
thank you guys (4 Replies)
Hello,
I need explanations about physical disks and physical volumes. What is the difference between these 2 things?
In fact, i am trying to understand what the AIX lspv2command does.
Thank you in advance. (2 Replies)
