Note: This is a template to ease development. The storage-vendor-specific part of the scripts have to be coded by yourself. An alternative way is to engage professionals to develop the script on one of the freelancing platforms . There sometimes comes a need to simplify complex operations, in this case failover and failback operations of SAN storage replication between sites (e.g. production and DR), for reasons such as letting operators or the less technically-confident colleagues to more easily perform the operations in case of disasters or drill tests. To achieve that, this template has been created. Written primarily in PowerShell, this package contains a set of SAN storage failover and failback scripts for Microsoft Failover Cluster (including Hyper-V cluster) and vendor-neutral pseudo code for SAN storage (for further modification to support different SAN vendors).

This is a quick guide on how to connect FC3171, a 8Gb QLogic SAN switch within IBM Flex System chassis, to a Brocade 300 SAN switch. By enabling transparent mode (also known as NPIV/N-Port ID Virtualization/Pass-thru/Access Gateway) on FC3171 and configuring port mapping, the WWNs of blade-internal hosts (there are 3 hosts in our example) can be detected by the upstream SAN switch (e.g. Brocade 300) successfully as shown in the outputs of portshow Brocade Fabric OS command below: Before
