TOPIC
The Mac OS X Server installer changes the partition type of the partition on which Mac OS X Server is installed. This change results in the partition not mounting in the Mac OS.
DISCUSSION When a user selects the drive or partition to install Mac OS X Server on to, the installer modifies the partition map so that the selected partition is no longer a Mac OS volume. The installer changes the type of partition to Apple_Rhapsody_Inst. This is the type of partition that the installer scripts recognize, thus allowing the files to be installed. Just before Mac OS X Server is installed, the installer scripts change the partition type again. This is because Mac OS X Server is a Unix-style operating system and must be installed on a UFS drive. This time the type of partition is changed to Apple_Rhapsody_UFS. After the installation process has successfully finished, or if it failed, the selected partition does not mount in the traditional Mac OS. This is because neither Apple_Rhapsody_Inst, or Apple_Rhapsody_UFS partition types do not mount in the Mac OS. So, these partitions are not accessible while in Mac OS. A common example of a failed install is if the user did not boot off of the Mac OS X Server CD. The partition types are changed, so the partitions do not mount. If the install failed, try running the installer again making sure the error is not procedural in nature. The installer can recognize both types of Apple_Rhapsody partitions, so if the partition is recognizable it sees it. The installer now lists the partition as either the "Mac OS X Server Install" partition or the "Mac OS X Server UFS partition." Select this partition and try to install again, following the procedures carefully. If the partition that had Mac OS X Server installed successfully or unsuccessfully, it must be reformatted with Drive Setup or another formatting utility that supports HFS or HFS+ in order for it to mount in Mac OS again. It may be possible to edit the partition map with pdisk back to a Mac OS volume, but Apple does not provide support for this. |
