IMPORTANT - HP StorageWorks 1000 Modular Smart Array: Announcing Advanced Active/Active Support (438764-021, February 2007)

Whether you are adding an MSA1000 to a new SAN, a SAN segment with other

active/passive devices, or a SAN segment with other active/active devices, you

must examine your network, understand the requirements of active/passive and

active/active configurations, and then determine which version firmware is best for

your environment.

For example, in a SAN with already-installed active/passive devices, you may

want to (or be required to) migrate those existing active/passive devices to

active/active. In addition, you may want to (or be required to) change to a new

multipathing software tool that supports active/active.

In addition to the information in this notice, be sure to confirm the latest list of

supported operating systems and any configuration restrictions for the different

firmware versions. See the two versions (active/active and active/passive) of the

MSA1000 compatibility guides, available on the MSA1000 website:

http://www.hp/com/go/msa1000

To upgrade this new stand-alone MSA1000 to
