Upgrading the Subsystem
171HP StorageWorks HSG60 and HSG80 Array Controller and Array Controller Software
Maintenance and Service Guide
Caution: Windows users who are upgrading their firmware version should
perform the following steps during the upgrade process:
a. Shut down the host system.
b. Perform a shutdown upgrade of the controllers.
c. Restart the host system.
Failure to perform the above actions prevents units from being presented with
the original disk letter and can cause you to lose access to unit data.
Upgrading to ACS V8.8-
x
F, V8.8-
x
G, V8.8-
x
L, and V8.8-
x
S
Use this section only if you are upgrading to ACS V8.8-xF, V8.8-xG, V8.8-xL,
and V8.8-xS. Upgrade ACS V8.8-xP by using the procedures in the “Upgrading to
ACS V8.8-xP software” section which starts on page 186.
Tip: If your site currently uses V8.6-
x
P but is not configured for DRM (single-controller
or dual-controller set to
NOREMOTE_COPY), you can upgrade the controller to
V8.8-
x
P by using the procedure in this section (“Upgrading to ACS V8.8-xF, V8.8-xG,
V8.8-xL, and V8.8-xS” on page 171). In this instance, treat the upgrade as though it
were for V8.8-
x
S to ensure that the Snapshot unit procedure steps are done.
Rolling upgrade procedure for dual-redundant configurations
This upgrade procedure applies only to dual-redundant controller configurations
and allows the disk units to be accessible to connected hosts during the upgrade
with minimal disruption. For single-controller configurations, see the “Shutdown
upgrade procedure for dual-redundant and single-controller configurations”
section that starts on page 181. Specific controllers are referred to as controller A
or controller B during the procedure. For clarity, the CLI prompts illustrated in the
procedure use HSGA> and HSGB> to indicate which controller (A or B) is used.
Note: Before initiating an ACS rolling upgrade, refer to the appropriate ACS solution
software installation and configuration guide for your operating system for additional
instructions. These procedures include considerations for solution software,
HP StorageWorks Secure Path, and switch firmware, as well as controller-based
upgrades. Specific instructions for the solution software and the proper sequence for
all components are included.
