HP StoreAll Storage Network Best Practices Guide

Sample ifconfig output for StoreAll node 2 after migrating the FM from StoreAll node 1 to
StoreAll node 2:
User VIF failover
To provide high availability to File Clients, HP recommends that StoreAll user networks use VIFs
for File Client requests. One node is selected as the primary node for the VIF and File Clients then
use this VIF when requesting files. The primary node is usually the node that returns those files.
Additionally, a second cluster node is set up a backup for that VIF, but the VIF will be in an inactive
state until it is needed for failover.
When the primary node is degraded and can no longer satisfy client requests, its User VIF can be
programmatically disabled, and the backup node can enable its User VIF. Any future client traffic
is automatically redirected to the backup node without the client needing to participate in the
failover. When the primary node is later restored to operation, the User VIF can be disabled on
the backup node and re-enabled on the primary node, causing the client to automatically switch
back to using the primary node for file requests.
