I should be able to use extra disks in a T5220 to store VMs:
Local storage consists of hard disks installed locally in your Oracle VM Server. In a default installation, Oracle VM Server will only use the first disk (/dev/sda), leaving other disks available for storage.
As long as no partition and data are present the device will be detected as a raw disk. The choice is yours to use the local disks either to provision logical storage volumes as disks for virtual machines or to install a storage repository. If you place a storage repository on the local disk, an OCFS2 file system is installed.
But I am unable to discover these disks using Oracle VM Manager 18.104.22.1680, managing a host running Solaris 11.1 with latest version of VM Server for SPARC:
# pkg list | grep ldom
consolidation/ldoms/ldoms-incorporation 0.5.11-0.175.1.9.0.4.0 i--
system/ldoms 0.5.11-0.175.1.9.0.2.2 i--
system/ldoms/ldomsmanager 22.214.171.124-0.175.1.9.0.4.0 i--
I suspect that it is because "partition and data are present" on the disk, but I don't know how to delete partitions with the format command, only change them to unassigned and zero length, and that didn't work:
Current partition table (original):
Total disk cylinders available: 46873 + 2 (reserved cylinders)
Part Tag Flag Cylinders Size Blocks
0 unassigned wm 0 0 (0/0/0) 0
1 unassigned wm 0 0 (0/0/0) 0
2 backup wu 0 - 46872 279.38GB (46873/0/0) 585912500
3 unassigned wm 0 0 (0/0/0) 0
4 unassigned wm 0 0 (0/0/0) 0
5 unassigned wm 0 0 (0/0/0) 0
6 unassigned wm 0 0 (0/0/0) 0
7 unassigned wm 0 0 (0/0/0) 0
I can't make slice 2 size zero, otherwise when I run label to write the changes I get an error. Can anyone tell me what I'm missing? Thanks!
The reason you can't do this, is that the currently shipping support for Oracle VM Manager on SPARC systems is only for NFS. The paragraph you are quoting is from the base Oracle VM manual and that section applies to x86. /dev/sda is a Linux convention, not Solaris, so it wouldn't apply here.
If you go to the Oracle VM Server for SPARC documentation at Oracle VM for SPARC Documentation and then select View Library for Release 3.0 at
you will see a page with all the documents for the current release. Pick the "Oracle VM Manager 3.2: Quick Start Guide for Managing Oracle VM Server for SPARC" at http://www.oracle.com/technetwork/server-storage/vm/ovm3-sparc-quick-start-guide-1900072.pdf
You are running the correct version of Solaris 11 and the logical domains manager, so you should be able to discover the server, networks, and file-based repositories, but you'll have to wait till a later release provides support for local disk, FC SAN, and iSCSI. I hope this helps explain the situation.
