54 HP StorageWorks MSA500 G2 Storage System User Guide
• To configure an MSA500 G2 storage system for controller redundancy, both
controllers must execute the same version of firmware. If the controllers have
different firmware versions, the storage system responds as follows:
– In a hot-plug addition of the second controller, the storage system clones
the firmware version of the active controller onto the second controller.
After the second controller is reset, the controllers become redundant.
– In a non-hot-plug addition of the second controller, the storage system
examines the firmware versions of both controllers at power up and
clones the most recent version from one controller to the other controller.
Installing the MSA500 G2 Controller
CAUTION: To prevent improper cooling and thermal damage,
do not operate the storage system unless all bays are populated with
either a component or a blank.
1. Remove the bezel blank.
2. Open the locking latch on the redundant controller.
