11 Migrating to an agile management
console configuration
The agile management console configuration provides one active management console and one
passive management console installed on different file serving nodes in the cluster. The migration
procedure configures the current Management Server blade as a host for an agile management
console and installs another instance of the agile management console on a file serving node. After
completing the migration to the agile management console configuration, you can use the original
Management Server blade as follows:
• Use the blade only as a host for the agile management console.
• Convert the blade to a file serving node (to support high availability, the cluster must have an even
number of file serving nodes). The blade can continue to host the agile management console.
To perform the migration, the X9000 installation code must be available. As delivered, this code is
provided in /tmp/X9720/ibrix. If this directory no longer exists, download the installation code
from the HP support website for your storage system.
IMPORTANT:
The migration procedure can be used only on clusters running HP X9000 File Serving Software 5.4
or later.
Backing up the configuration
Before starting the migration to the agile management console configuration, make a manual backup
of the management console configuration:
ibrix_fm -B
The resulting backup archive is located at /usr/local/ibrix/tmp/fmbackup.zip. Save a copy
of this archive in a safe, remote location, in case recovery is needed.
Performing the migration
Complete the following steps on the blade currently hosting the management console:
1. The agile management console uses a virtual interface (VIF) IP address to enable failover and
prevent any interruptions to file serving nodes and X9000 clients. In the migration, the existing
cluster NIC IP address becomes the permanent VIF IP address. Identify an unused IP address to
use as the Cluster NIC IP address for the currently running management console. Then reconfigure
the cluster and user networks:
• Edit the /etc/sysconfig/network-scripts/ifcfg-bond0 file. Change the IP address
to the new, unused IP address and also ensure that ONBOOT=Yes.
