Configuring SAN shared storage

When the Oracle VM Server is installed, it is installed on a local drive. To support many of the

features of Oracle VM, you need to create the Oracle VM storage repository on shared storage that is

available to all servers in a server pool. For the HP ProLiant DL785 G6, this whitepaper only

addresses the following Oracle VM SAN Shared Storage options:

• Shared storage using OCFS2 on SAN

• Shared storage using a partition (multi-path device)

If you use OCFS2, a SAN virtual disk is imported as a single storage device to all servers in the pool.

Then, an OCFS2 cluster file system is configured across all severs in the pool to expose the Oracle

VM repository to each server in the pool.

If you use a multi-path device, multiple virtual disks are exposed to servers in the server pool. OCFS2

is still configured on the first virtual disk of each server in the pool as in the first option. However, you

can attach the additional virtual disks to individual virtual machines for additional storage.

Configuring SAN shared storage using OCFS2

Before configuring SAN shared storage, ensure the FibreChannel cards in each server are in the

same zone as the storage so the EVA or MSA storage can see them. Also, create and present a SAN

virtual disk to all the servers in the pool so the virtual disk is shared among them.

To configure SAN shared storage using OCFS2, follow these steps:

1. Ensure that the virtual disk (for example, /dev/sda) is seen by each server in the pool, as follows:

# cat /proc/partitions

104 0 143338560 cciss/c0d0

104 1 104391 cciss/c0d0p1

104 2 3148740 cciss/c0d0p2

104 3 139026510 cciss/c0d0p3

104 4 1 cciss/c0d0p4

104 5 1052226 cciss/c0d0p5

8 0 209715200 sda

2. On one server in the pool, create a partition on the virtual disk with the fdisk or parted utilities

and ensure that the partition (for example, /dev/sda1) is seen by each individual server as
