Re: Install Fails on T5240



Also, 

According to this doc:

https://docs.oracle.com/cd/E19712-01/820-3318-14/820-3318-14.pdf

These systems require 1.5v FB DIMMS

FB-DIMM Configuration Guidelines for Sun SPARC Enterprise T5240 Servers
When planning FB-DIMM upgrades to Sun SPARC Enterprise T5240 servers,
observe the following memory configuration guidelines:
 ■ The motherboard has 16 slots that support industry-standard FB-DIMMs.
 ■ Use only 1.5-volt FB-DIMMs in SPARC Enterprise T5140 and T5240 servers.
 ■ Sun SPARC Enterprise T5240 servers support three FB-DIMM configurations:
 ■ 8FB-DIMMs (Group 1 in FIGURE: FB-DIMM Configuration on Motherboard
 (Sun SPARC Enterprise T5240 Servers) on page 101)
 ■ 12 FB-DIMMs (Groups 1 and 2 in FIGURE: FB-DIMM Configuration on Motherboard
 (Sun SPARC Enterprise T5240 Servers) on page 101)
 ■ 16 FB-DIMMs (Groups 1, 2, and 3 in FIGURE: FB-DIMM Configuration on
 Motherboard (Sun SPARC Enterprise T5240 Servers) on page 101) ■
 SPARC Enterprise T5240 servers can be equipped with a memory mezzanine
 assembly, which provides an additional 16 FB-DIMM slots.
 ■ All FB-DIMMs within a single CMP branch must have the same capacity.
 ■ If the System Firmware is at least version 7.1.7.f,
 the FB-DIMM capacities on different CPUs can be different.
 ■ When replacing a faulty FB-DIMM, the replacement FB-DIMM must have the
 same FRU part number as the FB-DIMM being replaced.
 If you are not able to obtain a replacement FB-DIMM with the same FRU part
 number, may need to replace all the FB-DIMMs in the branch to ensure that
 all FB-DIMMs in that branch have the same FRU part number.

Hi Jeremy,


Update: I was incorrect regarding the dimms they should be 1.8v. Note: The "Samsung M395T5160QZ4-CE66 0819" part number dimms work on my t5140 and t5120.

Pulled my t5140 and t5120 from storage, they are very similar to your t5240.   Experienced the same memory related issues, forgot about installing all matching dimms when I put these server away years ago.

Had a mixture of 16 ("Samsung M395T5160QZ4-CE66 0819"  and "Samsung M395T5160QZ4-CE66 0816"). Both systems didn't like that. Even though each dimm is 4GB and the part numbers seem similar, the difference with the revision "0819" vs "0816" caused a problem.  As such, I filled all 16 dimm slots with only "Samsung M395T5160QZ4-CE66 0819" and memory related errors stopped.

A) Regarding Memory Errors:

use ILOM CLI:

-> show faulty

For example: "show faulty" output shows dimm location /SYS/MB/CMP0/BR0/CH0/D0 as bad. To fix it:

--> set /SYS/MB/CMP0/BR0/CH0/D0 clear_fault_action=true

--> set /SYS/MB/CMP0/BR0/CH0/D0  component_state=Enabled

#you must do this for all devices/components listed within the show faulty output.

--> reset /SP

B) Regarding not being able to connect to ilom from a modern web browser with https:

* Will assume you already have ethernet mgmt port configured via ilom.

--> show /SP/network

Note: Disable https and enable http via ilom cli.

-->set  /SP/services/http servicestate=enabled

--> set /SP/services/http secureredirect=disabled
--> set /SP/services/https servicestate=disabled

*Please share if you have a better way.  Haven't had any luck with newer web browsers connecting to ILOM via https (on older servers like this).


C) Regarding being unable to connect to the t5140 ethernet mgmt port via ssh. add HostKeyAlgorithms=+ssh-rsa to your ssh.

For example:

ssh root@192.168.21.138

Unable to negotiate with 192.168.18 port 22: no matching host key type found. Their offer: ssh-rsa,ssh-dss

 $  ssh -o HostKeyAlgorithms=+ssh-rsa    root@192.168.1.18  (use ip of your t5240 management port).


D) Recommend you populate either 8 or 16 dimms according to the following diagram. Otherwise, "show faulty" may generate warnings/errors regarding degraded memory performance.

The following is helpful:

For T5140/T5240:

https://docs.oracle.com/cd/E19712-01/E21412-01/z40002fb1399759.html#z40002fb1400813

For T5120:

https://docs.oracle.com/cd/E19839-01/E21875-01/z40012191414552.html


E) Also recommend installing latest Oracle ilom/firmware for your t5240 server. (SysFW 7.4.11 based on ILOM 3.0 147310-15)
