Upgrading the Subsystem
12. Restore all snapshot units removed in step 4.
13. If the CCL was disabled in step 3, enable it using the following command:
HSGA> SET THIS_CONTROLLER COMMAND_CONSOLE_LUN
14. Mount the logical units on the host.
15. Disconnect the PC or terminal from the maintenance port of Controller A.

Upgrading to ACS Version 8.7P Software

ACS Version 8.7P implements the Data Replication Manager (DRM) feature, which
can also be upgraded using either a rolling or shutdown upgrade method. These
upgrade methods apply only to dual-redundant controller configurations.

Rolling Upgrade Procedure for 8.7P

The rolling upgrade procedure allows the disk to be accessible during the upgrade
process with minimal disruption. 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.
IMPORTANT: The following steps must be followed carefully for the upgrade procedure to work
properly.
This procedure takes approximately 10 to 20 minutes depending upon the complexity of the
configuration. The units involved are briefly unavailable twice during the procedures for
approximately 10 to 20 seconds in step 13 and step 17.
NOTE: The rolling upgrade procedure upgrades the initiator site controllers to a specific point
and then fully upgrades the target site controllers before finalizing the upgrade for the initiator
site controllers.
Begin the rolling upgrade by using the following procedure on the initiator site
controllers:
1. Connect a PC or terminal to the maintenance port of Controller A, at the initiator
site.
2. If the controller is running in SCSI-2 mode and the Command Console LUN
(CCL) is enabled, you must disable the CCL prior to upgrading.
a. Determine if the controller is in SCSI-2 mode and the CCL is enabled using
the following command:
HSGA> SHOW THIS_CONTROLLER
