Solution 1353995.1 : Sun Blade X6275 Server Module: How to find the node number in an X6275

Applies to:

Sun Blade X6275 Server Module - Version: Not Applicable to Not Applicable - Release: N/A to N/A
Information in this document applies to any platform.

Goal

The purpose of this document is to assist in identifying a node in a Sun Blade X6275 Server Module

Solution

How To identify the node in X6275

1) How do I identify the Node0/Node1 in Sun Blade X6275 ?

Ans: When you look at the board diagram (below) of the Sun Blade X6275, Node 0 is one the left. The right part of the blade is Node 1.

2) How do I Identify the nodes from the blade front panel ?

Ans: Looking at the front panel of the blade, number 0 shown is Node 0 and number 1 is Node 1 Sun Blade X6275 server module node numbering.

The node names for a single Sun Blade X6275 server module are identified as follows, As seen from the front of the blade installed in the chassis, the top node is 0 and the bottom node is 1.

Example : Blade front panel

Example: Node0

KEY:

0 - Node 0
1 - Node 1
2 - Server Module Locate LED
3 - Server Module Ready to Remove LED
4 - Server Module Service Action Required LED
5 - Server Module OK LED
6 - Server Module Power/Standby button
7 - Non-Maskable Interrupt (NMI) button (Service only)
8 - Universal Connector Port (UCP), used for dongle cable

3) How do I identify the Nodes from the Blade SP (ILOM) ?

Ans: Sun's Integrated Lights Out Manager (ILOM) resides on an integrated system service processor (SP) in the Sun Blade Server modules. Each node contains it's own SP ILOM with its own unique IPaddress.

Note: We can collect ILOM logs from the blade SP using the multi-port dongle cable amongst other connections.

a. Insert the multi-port dongle cable into the universal connector port (UCP) on the server module front panel.
b. Connect the multi-port dongle cable connections as appropriate.
c. The chassis also has an ILOM, called the Chassis Management Module (CMM) ILOM, which is used to manage chassis functions.
d .The SP ILOM can be accessed through its IPaddress, or through the Chassis Management Module CMM ILOM.

4) What is the supported CMM for X6275 ?

Ans: Sun Blade 6048 and Sun Blade 6000

5) How do I find the Nodes from ILOM/CMM (ILOM 2/ILOM 3) ?

Ans:

a ) ILOM 2.0 Node Numbering

The 2.0 CMM ILOM displays slot addresses as if there are two separate server Modules.

Node 0 is addressed by the actual slot number.
Node 1 is addressed by the slot number plus N, where N (number of slots )is 12 in a Sun Blade 6048 chassis and 10 in a Sun Blade 6000 chassis.

For example, For a server module in slot 6:
Node 0 is addressed by the actual slot number, 6.
Node 1 is addressed by:
- slot 18 (the actual slot number plus 12) in a Sun Blade 6048 chassis
- slot 16 (the actual slot number plus 10) in a Sun Blade 6000 chassis

This convention is reflected in the following CMM ILOM features: The /SYS/SLOTID target is different for the two blade ILOMs.

The chassis CMM ILOM provides separate targets for each blade. For example, If the blade is in slot 6, then the CMM ILOM identifies it as /CH/BL6 and /CH/BL18 in a Sun Blade 6048 chassis or /CH/BL16 in a Sun Blade 6000 chassis

The CMM ILOM web interface provides separate management displays for the two blade ILOMs, using the two slot IDs.

The node names for multiple Sun Blade X6275 server modules in a chassis are identified as follows: the node 0s are identified as BL0, BL1, ... BL11 from left to right; the node1s are identified as BL12, BL13, ... BL23 from left to right.

b) ILOM 3.0 Node numbering

ILOM 3.0 uses the actual slot number plus the node ID to identify modes.

For example in slot 6, the nodes are:
Slot 6, Node 0
Slot 6, Node 1
The CMM targets for the nodes in slot 6 are:
/CH/BL6/NODE0 for Node 0
/CH/BL6/NODE1 for Node 1

Note - For CMM ILOM 2.0.3.13 systems, A Sun Blade X6275 server module must be inserted into the chassis before you power on.

If the blade is not inside the chassis before you power on, ILOM does not recognize node 1. For ILOM 3.0 systems, this requirement does not apply.
