Installation Procedures - All Deployments Note: When examining the available firmware versions, consider the following: ■ The MSA ships with a single controller and active/passive firmware pre-installed. If you plan to install an additional MSA controller and are interested in upgrading to active/active, consider the complexity of your SAN, including the variety of device types, operating systems, failover tools, and access requirements. ■ Confirm the latest list of supported operating systems, servers, Host Bus Adapters, and any homogeneous/heterogeneous network limitations for the different MSA firmware versions.

Re-loading the older, active/passive firmware will result in the loss of all configuration information on the MSA. ■ active/active firmware is supported for use only on MSA with 256MB or greater controller cache modules.

HP StorageWorks 1500 Modular Smart Array Installation Guide
Note:
When examining the available firmware versions, consider the following:
■
The MSA ships with a single controller and active/passive firmware pre-installed. If
you plan to install an additional MSA controller and are interested in upgrading to
active/active, consider the complexity of your SAN, including the variety of device
types, operating systems, failover tools, and access requirements.
■
Confirm the latest list of supported operating systems, servers, Host Bus Adapters,
and any homogeneous/heterogeneous network limitations for the different MSA
firmware versions. See the two versions (active/active and active/passive) of the
compatibility guide, available on the Technical documents page of the MSA1500
website:
.
■
After upgrading the MSA to active/active firmware, it is not possible to downgrade
at a later time to an active/passive version.
Re-loading the older, active/passive
firmware will result in the loss of all configuration information on the MSA.
■
active/active firmware is supported for use only on MSA with 256MB or greater
controller cache modules. Before upgrading to active/active firmware, verify that
both MSA controllers meet this requirement.
■
For information on upgrading the MSA to active/active, see the migration
instructions for your operating system, available on the Technical documents page
of the MSA1500 website:
