HP StorageWorks 1510i Modular Smart Array installation and user guide (383070-002, July 2008)

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

theMSAchassisisrestarted.Iftheversionsaremismatched,thesystempromptstoclone

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.Duringthecloningprocess,

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 ﬁ rmware 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.
