Rolling Upgrade Procedure for Version 8.6-xP to 8.7P

The ACS Version 8.7P rolling upgrade procedure from ACS Version 8.6-xP 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 the controller used.

Note: The steps in this procedure

must

be followed exactly for the upgrade procedure to work

properly. This procedure takes 10 to 20 minutes per site, depending on the complexity of the

configuration. The units involved are briefly unavailable twice during the procedures for 10 to 20

seconds in step 11 and step 13.

In the procedures that follow, initiator site procedure steps are marked with an initiator symbol,

Target site procedures are marked with a target symbol,

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.

Initiator Site Upgrade Procedure

Begin the rolling upgrade by executing the following procedure on the initiator site

controllers.

I 1. Connect a PC or terminal to the maintenance port of Controller A at the initiator site. If

you cannot find the ACS Version 8.6 configuration, perform the process in Appendix A

now.

I 2. Delete any snapshot units by performing the following steps:

a. Identify all snapshot units:

HSGA> SHOW UNITS FULL

b. Record the configuration for each snapshot unit for later restoration.

c. Delete all snapshot units individually with the following command:

HSGA> DELETE snapshot-unit-name

I 3. Verify that all snapshot units are deleted:

HSGA> SHOW UNITS FULL

Note: If any snapshot unit remains, repeat step 2.
