Operating Systems Solaris Sharing a physical disk with an LDOM Post 303042254 by Michele31416 on Thursday 19th of December 2019 05:17:31 PM

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! :-)

NAME
hv_kvp_daemon -- Hyper-V Key Value Pair Daemon SYNOPSIS
hv_kvp_daemon [-dn] DESCRIPTION
The hv_kvp_daemon daemon provides the ability to store, retrieve, modify and delete Key Value pairs for FreeBSD guest partitions running on Hyper-V. Hyper-V allows administrators to store custom metadata in the form of Key Value pairs inside the FreeBSD guest partition. Administrators can use Windows Powershell scripts to add, read, modify and delete such Key Value pairs. The hv_kvp_daemon accepts Key Value pair management requests from the hv_utils(4) driver and performs the actual metadata management on the file-system. The same daemon and driver combination is also used to set and get IP addresses from a FreeBSD guest. The set functionality is particularly useful when the FreeBSD guest is assigned a static IP address and is failed over from one Hyper-V host to another. After failover, Hyper-V uses the set IP functionality to automatically update the FreeBSD guest's IP address to its original static value. On the other hand, the get IP functionality is used to update the guest IP address in the Hyper-V management console window. The options are as follows: -d Run as regular process instead of a daemon for debugging purpose. -n Generate debugging output. SEE ALSO
hv_vmbus(4), hv_utils(4), hv_netvsc(4), hv_storvsc(4), hv_ata_pci_disengage(4), hv_kvp(4) HISTORY
Support for Hyper-V in the form of ports was first released in September 2013. The daemon was developed through a joint effort between Cit- rix Inc., Microsoft Corp. and Network Appliance Inc.. AUTHORS
FreeBSD support for hv_kvp_daemon was first added by Microsoft BSD Integration Services Team <bsdic@microsoft.com>. BSD
