Configuring Automated Failover Manually - HP StoreAll 8800 Administrator's Manual

HA
A File Serving Node can be in the following states:
Registered: Configured but not operational.
Up: Operational.
Up-Alert: Server has encountered a condition that has been logged. Check the events log on
the Events tab.
Up-InFailover: Server is powered on and visible to the Management Server, and the
Management Server is failing over the server's segments to its standby server.
Up-FailedOver: Server is powered on and visible to the Management Server, and failover is
complete.
Down-InFailover: Server is powered down or inaccessible to the Management Server, and
the Management Server is failing over server segments to a standby server.
Down-FailedOver: Server is powered down or inaccessible to the Management Server, and
failover is complete.
Down: Server is powered down or not accessible to the Management Server, with no standby
server providing access to the server's segments.

Configuring automated failover manually

To configure automated failover manually, complete these steps:
1. Configure file serving nodes in backup pairs.
2. Identify power sources for the servers in the backup pair.
3. Configure NIC monitoring.
4. Enable automated failover.
1. Configure server backup pairs
File serving nodes are configured in backup pairs, where each server in a pair is the backup for
the other. This step is typically done when the cluster is installed. The following restrictions apply:
The same file system must be mounted on both servers in the pair and the servers must see the
same storage.
In a SAN environment, a server and its backup must use the same storage infrastructure to
access a segment's physical volumes (for example, a multiported RAID array).
For a cluster using the unified network configuration, assign backup nodes for the bond0:1
interface. For example, node1 is the backup for node2, and node2 is the backup for node1.
1. Add the VIF:
ibrix_nic -a -n bond0:2 -h node1,node2,node3,node4
2. Set up a standby server for each VIF:
ibrix_nic -b -H node1/bond0:1,node2/bond0:2
ibrix_nic -b -H node2/bond0:1,node1/bond0:2
ibrix_nic -b -H node3/bond0:1,node4/bond0:2
ibrix_nic -b -H node4/bond0:1,node3/bond0:2
2. Identify power sources
To implement automated failover, perform a forced manual failover, or remotely power a file
serving node up or down, you must set up programmable power sources for the nodes and their
