CAUTION: Failure to follow the recommendations and instructions for the rolling
upgrade feature may result in data loss or system inoperability. See the “Operating
Constraints” section for additional information.
CAUTION: Before attempting the ACS upgrade procedure in the “Rolling Upgrades”
section, verify that the subsystem is in a stable state. The HSG80 array controller
Reset button should be flashing, and all adjacent LEDs should be off (no light). Failure
to perform this verification may result in the loss of data or leave the HSG80 array
controller in an unusable state.
About Rolling Upgrades
There are two ways to upgrade the ACS:
• Using the rolling upgrade procedure—Rolling upgrades take advantage of HSG80
array controller failover capabilities and allow you to upgrade the ACS while I/O
activity continues.
• Using the shutdown upgrade procedure—The shutdown upgrade procedure
requires you to halt I/O activity, shut down your controllers, and dismount your
host systems and any associated units.
NOTE: Shutdown upgrade procedures are documented in the hp StorageWorks HSG80 Array
Controller V8.7 Maintenance and Service Guide that shipped with the HSG80 array controller.
You can download a copy of this guide from the HP website at http://www.hp.com. Follow the
storage-related links to access technical documentation for the HSG80 array controllers, which
are part of the HP StorageWorks Enterprise Modular Array and the HP StorageWorks Modular
Array.
