Ubuntu – HP DL380 G3 and Ubuntu

A few things to check...

• Have you upgraded the controller's firmware to the latest version 2.04? Often times, HP controllers introduce new or improved functionality in the form of firmware updates.
• The Smart Array P600 controller is one of HP's first attempts at SAS/SATA connectivity. It's still a PCI-X card, so it may not be fully compatible with the drives you're using. It's rated for 1.5G SATA (versus the more common 3G and 6G now).
• You're using consumer disks. There could be an issue there.
• I'd recommend upgrading the firmware of your server as well to the most current revision.
• Make sure you're working with current version of the SmartStart CD for Array configuration. Older versions of the software may have problems with that capacity of drive.
• If all else fails, look for a used Smart Array P400 controller. Your server has two PCI Express slots. Those would be better suited to storage controllers than the PCI-X slot you're using now.
• BTW - RAID 10 may make more sense with the size of the disks you're using. Lower rebuild times, better performance, etc.

Check init_autoloader.php in your application's base directory:

// Support for ZF2_PATH environment variable or git submodule
if (($zf2Path = getenv('ZF2_PATH') ?: (is_dir('vendor/ZF2/library') ? 'vendor/ZF2/library' : false)) !== false) {
    if (isset($loader)) {
        $loader->add('Zend', $zf2Path . '/Zend');
    } else {
        include $zf2Path . '/Zend/Loader/AutoloaderFactory.php';
        Zend\Loader\AutoloaderFactory::factory(array(
            'Zend\Loader\StandardAutoloader' => array(
                'autoregister_zf' => true
            )
        ));
    }
}

The simplest way is to set the ZF2_PATH env var. If you're running an apache web server, all you need to do this is mod_env. You can create a .htaccess file that sets the variable.

In case it still won't run, you can debug the init_autoloader.php file pretty easily.
