Configuring a Redundant Pair of VMA SAN Gateways - Process Guide

13
The fully de-configured and reinitialized gateway and array can now be used as ‘new’ to add to the
remaining gateway configuration according to the rest of the gateway pairing process. The
remaining gateway will now be referred to as the ‘primary’ gateway for the rest of this pairing
process.
Update the Primary VMA SAN Gateway
At this point in the process, one of the VMA SAN Gateways should have been identified as the
‘primary’ gateway of the redundant pair. The ‘primary’ gateway should also have a single PCIe
connection to the VMA Array(s), two arrays maximum, as shown in Figure 3 above. The secondary
gateway should not have any connection to the VMA Arrays or the network and should be shutdown.
Update the ‘primary’ VMA SAN Gateway with the appropriate version of VMA SAN Gateway
software OE update which supports redundant pairing. For initial release of Redundant Gateway
Pairs this will be gateway software OE version G5.1.0. Please refer to the HP VMA SAN Gateway
Software Update Guide (AM456-9022A) document available at www.hp.com/go/vma-docs
for step-
by-step details of the update process for the VMA SAN Gateway, including how to obtain the VMA
SAN Gateway software OE update.
After the update process of the VMA SAN Gateway software OE, which requires data access
downtime, also take time to install any additional VMA PCIe pass-thru cards (P/N AM464A) which
will be required later for connection of VMA Arrays. Always shutdown and disconnect the power
cords of a VMA SAN Gateway for installation of VMA PCIe Pass Thru cards.
If you are dually connecting one VMA Array to a redundant pair of VMA SAN Gateways, you will
need a PCIe pass-thru card installed in I/O slot #1 of both the ‘primary’ and ‘secondary’ VMA SAN
Gateways. If you are dually connecting two VMA Arrays, current maximum allowed, you will need to
install PCIe pass-thru cards in I/O slots #1 and #4 in each VMA SAN Gateway.
Figure 4: Back View of VMA SAN Gateway showing I/O Slots
The PCIe pass-thru cards, currently a maximum of two per gateway, must be in slots # 1 and 4 (in that
order) while the 8Gb FC HBAs are installed in slots # 2 and 3 for default configuration and optional
add-on FC HBAs are in slots # 5 and 6 in each VMA SAN Gateway. When a VMA Array is dually
connected to a redundant pair of VMA SAN Gateways, the FC HBAs, the PCIe pass-thru cards and
the cable connections on the gateways must be in the same I/O slot on both gateways. Also all the
primary PCIe port(s) of dually connected arrays to redundant pair gateways must be connected to one
gateway while all the secondary PCIe port(s) are connected to the other gateway. Please refer to
Figure 5 below for determining the primary and secondary PCIe ports on the back of the VMA Array.
