AM456-9007B Rev 02 HP VMA SAN Gateway Installation and User Guide 83
Figure 4.4 shows an illustration of a vSHARE HA configuration.
In this configuration, two HP VMA SAN Gateways are connected to a VMA Array.
The Array contains three partitions: private vSHARE metadata partitions for each
HP VMA SAN Gateway, and a shared partition containing storage that is
exportable by both Gateways. Data on the VMA Array is accessible via both Port
A and Port B.
Also see Standard System Configurations on page 233 for details on an HA
configuration involving more than two HP VMA SAN Gateways.
vSHARE High Availability Configuration Example
The procedure in this section shows an example of how to set up a vSHARE High
Availability configuration. In this sample configuration, two HP VMA SAN
Gateways are attached to a single HP VMA Array. A container, Strad201, is
created on the VMA Array and one LUN, FINANCE, is added to it. The FINANCE
LUN will be accessible via both HP VMA SAN Gateways.
1. Ensure that the HP VMA SAN Gateways are cabled correctly to the VMA
Array.
Note: For this example, Gateway MG-1 is connected to Port A on the Array, and
Gateway MG-2 is connected to Port B on the Array. In order for the HA
configuration to work properly, the two Gateways must be cabled to the Array from
identically numbered PCIe slots. That is, if you connect a cable from PCIe Slot 1
on Gateway 1 to Port A on the Array, then you must connect a cable from PCIe Slot
1 on Gateway 2 to Port B on the Array.
2. Ensure that the HP VMA Array has dual-port x4 firmware (A5.1 or greater)
loaded. An example filename would be v3000-a5-1-3-x4-slc.upg.
