Cloning Controller Firmware - HP StorageWorks 1510i - Modular Smart Array User Manual

13. View the messages displayed on the array controller LCD panel during startup to confirm that the
firmware was installed successfully and that the array controller restarts successfully.
NOTE:
In dual-controller configurations, firmware on the two controllers is compared each time
the MSA chassis is restarted. If the versions are mismatched, the system prompts to clone
the firmware on the controller with the latest version over to the controller with the earlier
version firmware. (For the system to operate in a dual-controller mode, firmware on the
controllers must match.)
The following message is displayed on the LCD panel of the controller with the earlier
firmware:
07 CLONE FIRMWARE ? '<' = NO, '>' = YES
Press the > button on the LCD panel to clone the firmware. During the cloning process,
informational messages are displayed on the controller LCD panels. When the cloning
process is complete, the just-updated controller automatically restarts.
Cloning controller firmware
NOTE:
Cloning is possible only in dual-controller configurations.
Each time a system with two controllers is powered on or restarted, or if a second controller is hot
plugged into a single-controller configuration, the firmware versions on the controllers are compared. If
the firmware versions on the two controllers differ, the array controller LCD panel prompts to clone the
firmware from one controller to the other controller, so that they have the same version.
The determination as to which firmware version is used is based on the following criteria:
• If the MSA is being powered up or restarted with both controllers installed, the most recent version
of firmware is used, regardless of which controller it resides on.
• If the MSA is already operating and an optional controller is hot plugged, then the version of firmware
that is on the original (non-hot plugged) controller is used, regardless of its version. This ensures that
any host-initiated I/O to the controller is not interrupted.
If the firmware version on the two controllers is not the same, the following prompt is displayed in the
controller LCD panel:
CLONE FIRMWARE ? '<' = NO, '>' = YES
If > is pressed or a response is not made to the prompt within 60 seconds, the following messages are
displayed on the LCD panel while firmware is copied from the active controller to the standby controller
and the standby controller is automatically restarted:
ROM CLONING STARTED
ARRAY CONTROLLER RESTARTING
STARTUP COMPLETE
The two controllers should now operate in redundant mode.
