7-14 Compaq Parallel Database Cluster Model PDC/O5000 for Oracle8i and Windows 2000 Administrator Guide I For the array controller pair installed in each storage subsystem, verify that the two ports on each array controller are connected to different Storage Hubs. I If an MA8000/EMA12000 Storage Subsystem has three or fewer disk enclosures, verify that a dual-bus I/O module with two SCSI cables is installed in each disk enclosure. Also verify that 14 or fewer disk drive units are installed in each disk enclosure. I If an MA8000/EMA12000 Storage Subsystem has four to six disk enclosures, verify that a single-bus I/O module with one SCSI cable is installed in each disk enclosure. Also verify that 12 or fewer disk drive units are installed in each disk enclosure. MA8000/EMA12000 Storage Subsystem Connectivity to FC-AL Connection Paths To ensure that an array controller is connected to the correct FC-AL path, open a CLI window and issue the CLI command show this_controller. If the port 1 topology is in an Offline state, refer to the StorageWorks documentation about the HSG80 Array Controller ACS and CLI for more information about how to configure an MA8000/EMA12000 Storage Subsystem. The topology for Port 1 on each array controller should be: I Loop Up state (not the Standby state) I LOOP_HARD Server Node Connectivity to FC-AL Connection Paths To verify that your servers are connected to all FC-AL paths, open a CLI window and issue the CLI command show connectionb. The output of this command shows status information about present and previous connections to all FC-AL paths including connection name, controller, controller port, adapter ID address, status, and unit offset. The status entry indicates the port is Online (connected) or Offline (disconnected). Rename the connection-name field to reflect the configuration of the array controllers (for example, SVR1TOP1 for node 1, top controller, port 1). This will improve your ability to view the FC-AL connections. For further information about controller properties, see "Setting Up and Configuring an MA8000/EMA12000 Storage Subsystem" in Chapter 5, "Installation and Configuration."
