Why Qlogic CTRL-Q doesn't show up when i boot my SUN x6250

If you also encounter this problem, problem most likely lie on your BIOS setting.

1. Go into your BIOS menu, press F2 while system is power on.
2. Go to Boot -> Boot Settings Configuration
3. And change the EM0 FUN0 OPTION ROM to enable (I have doubt on why there is FUN0 to FUN7 and i only need to enable FUN0, search internet but can't seems to find any explanation, if you know please post on the comments. However, i do know the Qlogic card plug at EM x.0 where x is the slot number)
4. Finally reboot and you should be able to see the CTRL-Q

Enable EM0 FUN0 OPTION ROM

Can see CTRL-Q

ELOM to ILOM for Sun Blade x6250

First of all, you need to download necessary files for this upgrade. Go to this link and look for sun blade x6250 entry. At the time of this writing, the latest firmware version is 2.0.4. After you downloaded the file, extract it out and look for this folder "Elom to Ilom". There are 2 important files inside:

• Telom_x6250-053_040.ROM - Traditional version of ILOM
• 6250i203.bin - ILOM image file

According to SUN documentation, you should upgrade your server module to the traditional version of ELOM before migrating it to ILOM.

Initially i like to do this upgrade through web GUI but it always give me the page error when i click the upgrade firmware button. Give up on web GUI, i turn to using command line and surprisingly, is not as hard as i thought.

For command line interface, the extra step you need to do is to prepare TFTP server if you don't have one. For my case, i use SolarWinds Free TFTP server to do it. After finish setup the TFTP server, just copy the 2 files mentioned above to the directory where you put it as root directory on your TFTP server.

The next step is to login to the command line of your server module and execute the following steps:

• cd /SP/TftpUpdate
• set ServerIP=xxx.xxx.xxx.xxx (your TFTP IP address)
• set FileName=Telom_x6250-053_040.ROM (the traditional ELOM)
• show (optional: just to make sure you provide correct information)
• set Update=action (and the update process begins)

Below shows the screen capture for the update process. Need to wait for couple of minutes before the server module up again.


The steps taken to update to ILOM are similar to steps taken to update to traditional version of ELOM mentioned above.

The video clip below shows what happen to the sun blade x6250 while updating.

MPXIO In Action

My Environment

Brocade switch:
Port 4, 5 connected to HBA and port 10, 11 connected to storage.

How i simulate?
1. Initiate a file copy process.
2. Simulate link breakdown by disable (portdisable) port 4 while file is still copying.
3. Simulate link recovery by enable back (portenable) port 4 while file is still copying.

From the video, you can see the drop of throughput on port 4 when i disable port 4 and the throughput on port 4 climbs up again when i enable back port 4.

Configuring MPXIO

My Environment:
Server: Sun Blade T6320
Storage: EMC CX3-20

Steps taken:

• Use format to inspect the luns that had been assigned to your system. In my test system, disk 4,5 and disk 6,7 are actually same lun with 2 paths.

Sun Solaris 10 Network Install (LAN)

My environment:
Sun Blade T6320, Platform Group: sun4v
Install Server: x86 with Sun Solaris 10
Install Server and Client (Target system for installation) sit on the same subnet

Sun Official Documentation:

Solaris 10 6/06 Installation Guide: Network-Based Installations

http://docs.sun.com/app/docs/doc/819-5776

Steps taken applicable to my environment:

1. Create install server

# mkdir -p install_dir_path ;Create a directory to save the image
# cd /cdrom/sol_10_1008_sparc/Solaris_10/Tools  ;the keyword here is Tools folder
# ./setup_install_server install_dir_path  ;execute the script, it might take some time here

2. Modify ur hosts file (/etc/inet/hosts)at your install server.
Example, if your new client (target system for installation) is named
hostname: newsol10
IP Address: 10.0.0.123

Your hosts file (/etc/inet/hosts) should have the following entry
10.0.0.123 newsol10

3. Create a file with the following path and name -- /etc/ethers and this file should have the following entry
0:14:fc:xx:yy:zz newsol10

You can obtain your machine MAC address by looking at the information while it is booting as below:

Sun Blade T6320 Server Module, No Keyboard

4. Add system to be installed using add_install_client

# ./add_install_client newsol10 sun4v

bash-3.00# ./add_install_client newsol10 sun4v

copying boot file to /tftpboot/inetboot.SUN4V.Solaris_10-1

5. Boot your client into OBP session (OK prompt) and at the ok prompt, type
ok boot net - nowin    ;into console mode installation

* I encoutered "timed out waiting for tftp reply" after typing the command above,
i not sure why but after i restart the install server as well as my client, the error goes away.

How to send break signal in ILOM

ILOM version = 2.0.4.19
System = SUN T6320

• Shutdown your Sun system. Numerous way to do it, one of them is using the ILOM webGUI as shown.

Shuting down the machine (click to see enlarged picture)

• Log in to 2 ILOM sessions using putty.
• In your first ILOM session, first go to /HOST namespace.

-> cd /HOST

• Type the following command and standby

-> set send_break_action="break"

• In your second ILOM session, first start the system by typing the following command

-> start /SYS

• After that, accessing the console through this command.

-> start /SP/console

• Wait until it shows your Ethernet MAC address information and before it goes into boot device, use your first ILOM session to send the break signal. In order not to miss the timing, you can send numerous break signals in the anticipation of the Ethernet MAC address information to show up as shown below.

Send the break signal while booting (click to see enlarged picture)

• And finally the {0} OK prompt.
