我们有一个Sun Sparc 5440服务器，最初有64 GB的RAM，我们试图升级到128 GB。 在此过程中，SCSI根盘似乎已经损坏，所以我们正在尝试重build系统。
我们有一个Solaris 10的DVD（一个要求，因为这台服务器镜像生产服务器）。 这是从Oracle下载的最新版本（sol-10-u11-ga-sparc-dvd.iso）。 当我们将DVD放入驱动器并执行boot cdrom它会突然停止一段时间，然后冻结。
我们已经证实，DVD在另一个Sparc系统上工作，所以我们已经排除了。
我们也排除了这是DVD驱动器（通过连接USB-DVD驱动器并从中启动）。
search后，我们尝试使用-v标志引导，这是我们看到的输出：

我们已经把它放在一夜之间，它永远不会进一步。
任何想法可能会出错或build议进一步debugging呢？
