About this document This guide provides information about migrating existing OpenVMS® MSA installations from a single-controller, active/passive configuration to a dual-controller, active/active configuration.
Related documentation for the MSA1500 User documents for the MSA1500 can be found in the shipping carton, on the Documentation CD, and on the MSA1500 Technical Documents web page: http://www.hp.com/go/msa1500cs.
Overview This document outlines the steps required to install new MSA dual-controllers, running active/active firmware, in an OpenVMS environment. This document also contains the steps required to migrate existing single or dual controller MSA active/passive firmware configurations to dual controller active/active configurations in an OpenVMS environment. NOTE: OpenVMS does not support MSA1500 configurations with active/passive firmware versions.
Step Description Check 1 Review or obtain the following documents on the MSA website: F • QuickSpecs • Command Line Interface User Guide • MSA1000/1500 Firmware Updating Guide MSA 1500 website: http://www.hp.com/go/msa1500cs MSA 1000 website: http://www.hp.com/go/msa1000 Obtain the latest active/active controller firmware files (version 7.0 or later). Go to the MSA website, and then click Software, firmware & drivers. 2 Backup the OS and data volumes.
Upgrading the MSA to active/active When upgrading your firmware to active/active determine which of the following matches your existing configuration: Upgrading existing single MSA1000 controllers to active/active Step Description Check 1 Install the additional MSA array controller and I/O module using instructions shipped with the controller. This can be done while the OS is still booted.
Installing new MSA1500 controllers active/active (data device only) Step Description Check 1 Install both MSA array controllers using instructions shipped with the controllers. F NOTE: Ensure that both controllers have the same cache size installed. The message, MSA STARTUP COMPLETE displays on each controller LCD panel when the controllers boot. 2 At the MSA CLI, add connections as required for server HBAs, ensuring that the profile is set to OpenVMS.
Installing new MSA1500 controllers active/active (system disk/device) Step Description Check 1 Install both MSA array controllers using instructions shipped with the controllers. F NOTE: Ensure that both controllers have the same cache size installed. The message, MSA STARTUP COMPLETE displays on each controller LCD panel when the controllers boot. 2 At the MSA CLI, add connections as required for server HBAs, ensuring that the profile is set to OpenVMS.
Verifying Step Description Check 1 Verify the new firmware version as specified in the MSA1000/1500 Firmware Updating Guide. F 2 Verify that all MSA devices and LUNs are visible, and that all connected HBA paths are present and responding. From the server console, enter: SHOW DEV DG/FULL F The output should be compared to the output recorded in step 5, page 6 of ”Preparing for the migration”.
