Note:
If the network settings did not appear after restart, then power cycle the switch
by removing both power cords for one minute.

Database Machine Full Rack and Oracle Exadata Database Machine
Half Rack
Oracle Exadata Database Machine X3-2 systems and Oracle Exadata Database
Machine X2-2 systems have three Sun Datacenter InfiniBand Switch 36 switches.
Starting with Oracle Exadata Database Machine X4-2, Oracle Exadata Database
Machine Two-Socket Systems have two Sun Datacenter InfiniBand Switch 36
switches.
The switch located in rack unit 1 (U1) is referred to as the spine switch. The other two
switches are referred to as the leaf switches. The location of the leaf switches is as
follows:
• Oracle Exadata Database Machine Two-Socket Systems (X3-2 and later): rack
unit 20 (U20) and rack unit 22 (U22)
• Oracle Exadata Database Machine X2-2 racks: rack unit 20 (U20) and rack unit 24
(U24)
• Oracle Exadata Database Machine Eight-Socket Systems (X2-8 and later) Full
Racks: Rack unit 21 (U21) and rack unit 23 (U23)
The spine switch is the Subnet Manager Master for the InfiniBand subnet. The Subnet
Manager Master has priority 8, and can be verified using the following procedure:
1. Log in to the spine switch as the
root
user.
2. Run the
setsmpriority list
command.
The command should show that
smpriority
has a value of 8. If
smpriority
has a
different value, then do the following:
a. Use the
disablesm
command to stop the Subnet Manager.
b. Use the
setsmpriority 8
command to set the priority to 8.
c. Use the
enablesm
command to restart the Subnet Manager.
The leaf switches are the Standby Subnet Managers with a priority of 5. This can be
verified using the preceding procedure, substituting a value of 5 in the
setsmpriority
command above.
