DESCRIPTION: LCD Panel May Freeze In a Cluster Setup
When a user sets up a cluster configuration using the LCD panel, the LCD on the slave appliance may freeze if the Up button on the front panel is repeatedly pressed. Initially the panel displays the details for the internal, external and broadcast IP addresses and after that it shows a blank screen. This doesn't affect the functionality of the appliance; both the master and slave nodes continue to work properly.
Once the user reboots the slave node, it starts functioning properly but now the master node may display the same behavior.
While there is no workaround available for this issue, the version 10.0 release (Grand Teton) incorporates new software for the LCD panel that resolves this issue.
