Migrating an existing cluster to a 10 GbE bonded configuration

When upgrading to 10 GbE HP StorageWorks P4000s that have bonded NICs and are already in
a cluster and providing storage volumes, you must follow certain steps to ensure an effective migration
to the new hardware configuration. This migration guide covers one possible bonded configuration
— the ALB bond configured with two 10 GbE interfaces as an ALB bonded pair.

Installation overview

The example below shows how to migrate existing HP StorageWorks P4000s configured with a 1
GbE ALB bond to a configuration with a two 10 GbE NICs configured with an ALB bond. For this
example, the other two Ethernet interfaces in the storage nodes are not used by the SAN/iQ software
and can be disabled.
The example below utilizes planned downtime of the entire management group and results in none
of the volumes needing to restripe data. However, all access and I/O to the volume(s) is disconnected
during this upgrade period.
A summary of the installation and migration steps follow:
1. Stop all I/O and disconnect all iSCSI sessions to volumes.
2. Shut down management group and power off all storage nodes.
3. Install 10 GbE Ethernet adapter and additional memory in each storage node.
4. Power on each storage node and install the appropriate software patch, as described in the
P4000 10 GbE Hardware Installation Instructions.
5. Configure new IP address and bonds for 10 GbE on each storage node, and change the SAN/iQ
communication IP address.
