Modifying Physical Cluster Resources in a Compaq Parallel Database Cluster 6 What happens when the drive numbering order changes? When the numbers associated with the shared drives change the symbolic link table files are no longer correct. Each of these files must be modified to reflect the changes in disk structure. Returning to the example worksheet given above, assume that two physical disks are added to the first fibre channel array, and that the physical disks are configured as a single RAID logical drive with at least 3 partitions. In disk administrator the ordering of the disks in the second array changes. The symbolic link table file must be changed. Note: If the cluster consists of more than two nodes, the other symbolic link table files need to be modified as well. Thus, the new configuration of the cluster as seen by disk administrator is: Node1 Disk 0 Disk 1 Disk 2 Disk 3 Disk 4 Disk 5 Disk 6 Disk 7 An internal disk An internal disk Shared storage disk Shared storage disk Shared storage disk Shared storage disk Shared storage disk Shared storage disk Node2 Disk 0 Disk 1 Disk 2 Disk 3 Disk 4 Disk 5 Disk 6 An internal disk Shared storage disk Shared storage disk Shared storage disk Shared storage disk Shared storage disk Shared storage disk ECG001/1298
