gateways if desired. The rest of this pairing process will continue to refer to configuring two
Ethernet switches as part of the redundant gateway pairing process.
Please refer to the ‘VMA SAN Gateway Management and Configuration’ section of the ‘HP VMA
SAN Gateway Installation and Configuration Guide’, P/N AM456-9025A for additional details and
guidance on network planning.
Determine Gateway Pairing Scenario and Establish Primary Gateway
As mentioned previously, there are three possible scenarios for establishing a redundant pair of
VMA SAN Gateways:
• Starting with two new (or previously fully de-configured) gateways and forming a redundant
gateway pair with two new (or previously initialized) VMA Arrays.
• Adding a new (or previously fully de-configured) gateway to an existing (configured)
standalone gateway configuration to form a redundant gateway pair.
• Have two existing stand-alone gateways, each with only one connected array, and wish to
use these two gateways to form a redundant pair with two dually connected arrays. Note
that in this case one of the existing gateway configurations will be used as the ‘primary’
gateway and the other gateway and array will be re-initialized to add in as though new.
Determine which of the above scenarios match your situation and perform the appropriate steps
according to the subsection below that is applicable to your scenario. Upon completion of the
appropriate subsection, you should have established which gateway will be the ‘primary’ and which
will be the ‘secondary’ gateway in the redundant gateway pair.
Starting with two new VMA SAN Gateways
With this scenario, you will follow all the steps below in order to select one gateway to become the
primary gateway and configure it with initial settings. The VMA Arrays, up to two, will also need to
be connected and initialized as part of preparation for this scenario.
Of the two new VMA SAN gateways, select which gateway will be the ‘primary’ gateway for the
redundant pair. A unique vSHARE license key and Cluster ID have been pre-configured with every
HP VMA SAN Gateway; however, for a redundant gateway pair you will later in the pairing process
use the Cluster ID on this primary gateway to prepare the secondary gateway for introduction into
the redundant pair. Note that each gateway will always retain their unique vSHARE license key and
Cluster ID label on the top, right front of the server enclosure; however, after completion of the
pairing process both the primary and secondary gateways will electronically share the vSHARE
license and Cluster ID of the initial primary system.
The initial step is to configure the selected ‘primary’ VMA SAN Gateway with all the intended
(maximum two) VMA arrays connected to it as a ‘stand-alone/master’ gateway. The process of
installing the VMA PCIe Pass-Thru cards and connecting up to two VMA Arrays to the VMA SAN
Gateway is the same as with the initial G5.0.2 release of the VMA SAN Gateway (G5.0.2). It is
recommended that any VMA PCIe Pass Thru cards required for VMA Array connectivity to the
gateway is installed in I/O slots # 1 and 4 (in that order) of the VMA SAN Gateway at this time.
Follow the setup instructions in the ‘VMA SAN Gateway Management and Configuration’ subsection
of the ‘HP VMA SAN Gateway Installation and Configuration Guide’, P/N AM456-9025A for details
on how to configure a standalone VMA SAN Gateway and connect the VMA Arrays.
