Solaris Issues

Note – The Sun Blade X6440 is delivered with a preinstalled Solaris OS. This OS is set by default to be redirected through the serial console connection (ttya). To change this to local monitor/keyboard, use the GRUB menu at boot time, and select the VGA option.

Warning message might appear during startup

When using a compact flash device, the following warning message might appear during Solaris startup:

WARNING: /pci@0,0/pci-ide@4/ide@0 unable to enable write cache targ=0

It is safe to ignore this message.

Solaris OS installation halts during the installation

Change Request ID: 6848353

When installing the Solaris OS in a system that contains an LSI 1068e B3 HBA, the installation halts at the “Configuring Devices” screen. This issue does not occur when using other HBA cards in the system.
