Optional Features The tool ICPCON.NLM facilitates the administration of the cluster arrays. Note that a cluster array can only be managed and serviced from one server. Access to this cluster array from other servers (with ICPCON running) is not permissible. Normally, this is the server in the cluster which was started first and which has found the cluster array before the other servers. Should this specific server fail, all administration rights are migrated to another, valid server. A server console message notifies the server administrator of this event. A.1.6.6. Restrictions Cluster Arrays cannot be expanded online. The Cluster must be shut down (all servers) and the following steps observed: 1. Shut down the Cluster with all its individual servers and switch them off. 2. Switch on only one of the servers and enter ICPCON with +. 3. Change the drive type of the Cluster Array into "Private". 4. Expand and/or migrate the array and wait until this process is completed. 5. Change the drive type of the Cluster Array back into "Cluster". 6. Restart the Cluster. A.1.6.7. Notes on the ICP RAID Navigator (ICP RAID Navigator) A detailed description of the ICP RAID Navigator is covered in Chapter 11, ICP RAID Navigator of this guide. Display of shared I/O channels within ICP RAID Navigator is illustrated in Figure A-3. This example shows a shared SCSI channel with five SCSI hard disks. Two of the hard disks set up as a RAID 1 disk array and currently mounted on the ICP RAID controller of the other node and are not visible here. You could use the Cluster Administrator for Windows NT/2000 to move this resource back to the displayed ICP RAID controller. Figure A-3. Channel Information Software Installation and User's Guide 201
