Pedestal End-Bus RAID Cluster Layout
Perform the following steps to connect two (Intel) host servers equipped with
HD-68-pin host adapters to the pedestal subsystem located on the end of the
UltraSCSI bus (Figure 3– 2):
1. Attach a Y-cable (BN21W-0B) to the HD 68-pin host adapter on
Host A.
2. Attach a Y-cable (BN21W-0B) to the HD 68-pin host adapter on
Host B.
3. Attach one end of the HD 68-pin straight-thru cable (BN21K-05) to a
convenient end of the Y-cable attached to Host A.
4. Connect the other end of the cable to a convenient end of the Y-cable
attached to Host B.
5. Attach the compatible end of adapter cable (BN38E-0B) to the available
end of the HD 68-pin Y-cable attached to Host B.
6. Connect the other (VHDCI compatible) end of the adapter cable to
either Host Port 0 or Host Port 1 in the back of the RAID subsystem.
Only one host port is used in a cluster.
NOTE: The host port used must correspond to that specified in your storage set
configuration.
7. Connect terminator H879-AA to the available end of the Y-cable
attached to Host A.
