3. Reboot THIS_CONTROLLER during a slow time (when controllers are running at

more than 50% idle). The patch takes effect once the controller is rebooted.

4. Repeat these steps for

OTHER_CONTROLLER by moving all units to

THIS_CONTROLLER and rebooting OTHER_CONTROLLER during a slow time.

ACS Patch Memory

Any installed ACS Version 8.6 (or lower) patches should be removed after an ACS

Version 8.7 installation since they are no longer applicable. This frees up HSG80

patch memory for future ACS patches.

To check or remove ACS patches, run the Code Load and Code Patch utility by typing

the following command:

HSG80> RUN CLCP

Multiple Storage System Types

The extended interoperability of the heterogeneous SAN allows you to mix several

types of StorageWorks storage systems. StorageWorks recommends the following

configuration rules when different storage products are shared in the same SAN:

• HSG80 ACS Version 8.7 and EVA VCS Version 2.0—Use ACS Solution Software

Version 8.7A (includes SWCC Version 2.5) and VCS Version 2.0 compatible

multi-bus software/drivers.

• HSG80 ACS Version 8.6 and EVA VCS Version 2.0—Use ACS Solution Software

Version 8.6 (if SWCC Version 2.4 components are desired) and VCS Version 2.0

compatible multi-bus software/drivers.

• HSG80 ACS Version 8.6 and HSG80 ACS Version 8.7—Use ACS Solution

Software Version 8.7A (includes SWCC Version 2.5).

NOTE: Any multiple storage system configuration that includes EVA VCS Version 2.0 requires

multi-bus support. See "Secure Path Software", page 26, for compatible Secure Path versions.

ACS Version 8.7 compatible Secure Path versions and HBA drivers are compatible with VCS

Version 2.0.
