Disk Group Alignment and Encapsulated Disks

On the Solaris OS, all native file systems are cylinder aligned. Encapsulating such a disk results in subdisks that are also cylinder aligned. Such alignment will normally not be 8K aligned, but it will be 1K aligned. For the encapsulation process, there is no flexibility as to where on the disk the subdisks must be since the data location is predefined. If an alignment conflict occurs, user intervention is required. If the disk group alignment is 8K this operation will probably fail because this would require the cylinder to be an even number of 8K blocks in size.
