HP StorageWorks 1000/1500 Modular Smart Array active/active firmware 7.0 Release Notes (434889-002, February 2007)
Critical: Do not upgrade to this version of firmware without first fully reviewing the following
technical documents located on the Technical Documents page of the following HP websites:

• MSA1000 active/active compatibility guide
Critical: On the MSA1000, downgrading from active/active firmware version 7.00 to active /passive
firmware 4.x is not suppor ted and will result in the loss of the array configuration. If migration back to
active/passive firmware is necessary, a full data backup and recording of the array configuration on the
MSA1 0 00 is required. (Note: Downgrading from active/active firmware version 7.00 to a ctive/passive
5.10 does not affect the MSA1500.)
Critical: Secure Path for Linux and Secure Path for Windows software does not work with firmware
version 6.x or later.
See the migrating to active/active guides for instructions on moving to the suppor ted multi-path software
utilities.
Critical: Before upgrading to firmware 7.00, the MSA1000/1500 Support Software CD version 7.6x
or later must be d ownloaded and used to update host drivers and utilities that are compatible with the
active/active firmware.
See the MSA1000 or MSA1500 installation guide for installation instructions.
Critical: Hot removing an operational array controller from the MSA1000 or MSA1500 is not s upported
and could cause the surviving controller to be come unresponsive. For instructions on how to properly
disable and remove an operational array controller, see the MSA1000 or MSA1500 maintenance
and service guide, available on the following HP websites: h
ttp://www.hp.com/go/msa1000 or
h
ttp://www.hp.com/go/msa1500cs.
Critical: A s with any firmware update, be sure that there is a current g ood backup available first.
Critical: When upgrading firmware to version 7.00 using the MSA command line interface (CLI) method,
use of the CLI command ’download firmware online’ i s not supported. If you choose to use the MSA CLI
method to update firmware, only use the ’download firmw are offline’ CLI command.
Important: After migrating to active/active firmware, LUNs should be distributed between two controllers
for best performance. See the Redundancy Settings section of the Array Configuration Utility user
guide or the Show/Set preferred path CLI command in the MS1000/1500 Command Line Interface
user guide for additional instructions.
Important: For best per formance, do not enable host-side HBA load balancing if the host-specific
multi-path software supports this feature. Due to the single Fibre Channel port p er controller design
of the MSA1000 and MSA1 500, enabling host-side HBA load balancing could actually decrease
overall per formance. See the host-specific multi-pa th software documentation for instructions on
enabling/disabling the HBA load-balancing features.
Important: Do not turn off p ower to the MSA1000 or MSA1500 or connected d rive shelves while hosts
connected to the MSA1000 or MSA1500 are online and processing host I/Os. HP recommends the
