Understanding mirror disk resources Dependencies of mirror disk resources Mirror disk By default, this function does not depend on any group resource type. Section II Resource details Understanding mirror disk resources Mirror disks are a pair of disks that mirror disk data between two servers in a cluster. Mirroring is performed by partition. It requires the RAW partition (cluster partition) to record the management data as well as the data partition that is to be mirrored. In addition, the license of ExpressCluster X Replicator 2.0 for Windows is necessary on both servers that mirroring is performed. The specifications of the disks need to be the same on both servers in order to use them as mirror disks. Examples: � Disk type and geometry The size of the data partitions has to be completely the same by byte on both servers. If the disk size and geometry are different on each server, it may be unable to create partitions that are exactly the same size. Thus the geometry of disks which are used to secure data partitions needs to be the same on both servers. It is recommended to use disks of the same model on both servers. Example: Combination server1 server2 Correct SCSI SCSI Correct IDE IDE Incorrect IDE SCSI Combination Head Sector Cylinder Correct Incorrect server1 240 63 15881 server2 240 63 15881 server1 240 63 15881 server2 120 63 31762 If it is not possible to make both servers have exactly the same disk type and geometry, check the size of data partitions in precise by using the clpvolsz command. If the disk size does not match, shrink the larger partiotin by using the clpvolsz command again. For more information about the clpvolsz command, see “Chapter 4 ExpressCluster command reference.” 443
