CHAPTER 1 Host Connections This chapter contains configurations for one or two Sun StorEdge A3000 controller modules connected to one or more hosts. It also contains information about connecting power to an Ultra™ host system.
1.1 Configuration Guidelines Use the following guidelines for installing and cabling or reconfiguring your system. ■ Do not exceed a SCSI bus length of 25 meters. ■ Make sure that the last Sun StorEdge A3000 controller module in any daisy chain has a total of two terminators, one in each SCSI OUT port. ■ If you are adding a controller module to an already existing configuration, halt all activity on the SCSI bus before removing any SCSI cables.
1.2 Supported Host Configurations The examples that follow show the cable connections for configurations that are supported by Sun Microsystems™. 1.2.
1.2.2 Daisy Chain You can daisy chain controller modules in the same or separate cabinets. SCSI cables FIGURE 1-2 Differential SCSI terminators Two Sun StorEdge A3000 Controller Modules Daisy Chained to One Host Note – The SCSI cables between the two controller modules are crossed to prevent the SCSI IDs for the controllers from conflicting.
1.2.
1.2.4 Multi-Initiator FIGURE 1-4 Two-Node Multi-Initiator Configuration Note – For more detailed information regarding the two-node multi-initiator configuration, such as setting host SCSI IDs, refer to the SPARCcluster™ PDB™ documentation that is shipped with the host system.
1.3 Ultra 2 Host System—Power Connection Requirement You can connect a controller module to an Ultra 2 host system; however, you must connect the power cord of the Ultra 2 host to one of the AC power sequencers in the expansion cabinet that contains the controller module.
1. Gain access to the AC power sequencers. See the documentation that came with the expansion cabinet. 2. Route the power cable from the Ultra 2 host under the expansion cabinet frame on the same side as the power sequencer. 3. Plug the power cord from the Ultra 2 host into the top power connector of either power sequencer (FIGURE 1-5). The power connectors are located on the other side of the power sequencer from the main switch. 4. Reassemble the expansion cabinet.
CHAPTER 2 StorEdge A3500 Configurations This chapter contains information about setting up the following configurations: ■ ■ ■ ■ One controller module with two StorEdge D1000 disk arrays (1x2) One controller module with five StorEdge D1000 disk arrays (1x5) Two controller modules with seven StorEdge D1000 disk arrays (2x7) Three controller modules with fifteen StorEdge D1000 disk arrays (3x15) The chapter is divided into the following sections: ■ StorEdge D1000 Disk Array Settings—page 2-2 ■ 1x2 Config
2.
2.1.1 1x2 Configuration 2.1.1.1 Option Switch Both disk arrays have split busses. Their option switches should be set as shown in FIGURE 2-2. 5 4 3 FIGURE 2-2 2 1 1x2 Option Switch Settings for StorEdge D1000 Disk Array This will cause the disk drives in the StorEdge D1000 disk arrays to be numbered as shown in FIGURE 2-3 and FIGURE 2-4.
2.1.1.2 Module ID Switch Ensure that the module IDs for the StorEdge D1000 disk arrays are set according to . 1x2 Module ID Switch Settings Disk array number Module ID setting 2 (Top) 2 1 (Bottom) 1 Note – Since the top and bottom disk arrays are split between one controller module, the Module IDs will overlap. This may result in error messages while the host system is booting. The ASC/ASCQ codes for this error is 98/01 and the Sense Key is 6.
2.1.2 1x5 Configuration 2.1.2.1 Option Switch All StorEdge D1000 disk arrays in this configuration should have their option switches set as shown in FIGURE 2-5. 5 4 3 FIGURE 2-5 2 1 1x5 Option Switch Settings for StorEdge D1000 Disk Array This will cause the disk drives in the StorEdge D1000 disk arrays to be numbered as shown in FIGURE 2-6 and FIGURE 2-7.
2.1.2.2 Module ID Switch Ensure that the module IDs for the StorEdge D1000 disk arrays are set according to TABLE 2-1. TABLE 2-1 2.1.2.3 1x5 Module ID Switch Settings Disk array number Module ID setting 5 (Top) 5 4 4 3 3 2 2 1 (Bottom) 1 SCSI Jumper Cables and Terminators All disk arrays in this configuration should have SCSI jumper cables between the middle SCSI connectors (IN/OUT-1 and IN/OUT-2) and a differential SCSI terminator in the far right SCSI connector (IN/OUT-2).
2.1.3 2x7 Configuration 2.1.3.1 Option Switch The disk drives in each of the top four disk arrays in FIGURE 2-17 are on a single bus and should be set as described in Section 2.1.2.1 “Option Switch” on page 2-5. The bottom three disk arrays have split busses. Their option switches should be set as shown in FIGURE 2-8.
2.1.3.2 Module ID Switch Ensure that the module IDs for the StorEdge D1000 disk arrays are set according to TABLE 2-2. TABLE 2-2 2x7 Module ID Switch Settings Disk array number Module ID setting 7 (Top) 5 6 4 5 5 4 4 3 3 2 2 1 (Bottom) 1 Facing the front of the expansion cabinet: ■ controller module A controls the right side of disk arrays 1 through 3 and all of disk arrays 4 and 5. ■ controller module B controls the left side of disk arrays 1 through 3 and all of disk arrays 6 and 7.
2.1.4 3x15 Configuration 2.1.4.1 Option Switch All disk arrays are on a single bus and should be set as described in Section 2.1.2.1 “Option Switch” on page 2-5. 2.1.4.2 Module ID Switch Ensure that the module IDs for the StorEdge D1000 disk arrays are set according to TABLE 2-3 and TABLE 2-4.
In this configuration: 2.1.4.
2.2 1x2 Cabling The 1x2 can be configured with the controller module either on top of or below the two disk arrays. Both configurations are described in this section. 2.2.1 SCSI Cabling 2.2.1.1 Cable Lengths The following table shows the lengths of each SCSI cable connected to the drive connections on the controller module.
