Maintaining the Sun Fire V20z Server |
This chapter describes how to add, replace and configure components in the Sun Fire V20z server after it has been set up.
For instructions on maintaining a Sun Fire V40z server, see Chapter 5.
This chapter contains the following sections:
To determine and isolate a faulty component, refer to Troubleshooting and Diagnostics.
Perform this procedure to observe safety guidelines when you are powering off the system and removing the cover for a maintenance procedure in this chapter:
1. If the system OS is running, perform a shutdown of the OS, then press and release the platform power button on the front panel.
2. Turn off all peripheral devices connected to the system.
3. Turn off the AC power switch on the rear panel of the server (see FIGURE 1-2). Leave the AC power cord attached to the power supply to maintain system ground.
4. Turn off power to any attached peripherals.
5. Label and disconnect all peripheral cables and all telecommunication lines connected to I/O connectors or ports on the back panel of the system.
|
Caution - The system's printed circuit boards and hard disk drives contain components that are extremely sensitive to static electricity. |
6. Before handling components, attach a wrist strap to a chassis ground (any unpainted metal surface).
7. Pull the cover toward the server front slightly, then press the cover latch release button with your right thumb (A) and slide the cover towards the rear of the chassis until it contacts the stop (B) (see FIGURE 4-1).
8. Lift the cover up and remove it.
When replacing the top cover on the Sun Fire V20z server after component installation, use caution to avoid damaging the cover or server components.
Remove all peripheral cables from PCI cards before installing the cover. If you install the server cover with PCI card cables installed, a lip on the edge of the server cover and the EMC foam gasket inside that lip may catch parts of the PCI card connectors and, in some cases, may deform the server cover seal or damage the connector latches.
Ensure that the power-supply cable is properly installed. The server cover may not close properly or may be difficult to close, and server performance may be affected if the power-supply cable is not properly installed.
The power-supply cable must be routed and pressed down such that it does not interfere with the cover installation. The power-supply cable must be tucked into a position such that the cable and its associated tie-wraps are not below the top surface of the power supply. Rotate the tie-wraps downward so that they do not protrude above the cable itself.
Refer to FIGURE 4-2 to locate components before performing the remove and replace procedures.
The following figure indicates the location of each of these components:
The ID assignments for the SCSI hard disk drives (HDDs) are as follows. Looking from the front of the server:
If you have a single SCSI HDD, the drive can be inserted in either slot. If you have two HDDs, the drive with the OS boot sector must be installed in the lowest-numbered slot among the populated slots.
The Solaris boot disk must be installed in SCSI slot 0.
The following sections highlight some issues that you should take into account when performing the remove-and-replace procedures in this chapter.
When the Sun Fire V20z server first shipped, the CPUs were at stepping version "C0". Since then, the CPUs have been stepped up to version "CG".
If you order an CPU X-option to add or replace a CPU in your server, do not mix CPUs of different stepping versions.
Before ordering a new or replacement CPU, verify the stepping version of your CPU(s) and then order the same stepping version.
To verify the stepping version of your CPU(s) in a local server (with KVM attached):
1. Power on or reboot your server.
A message similar to the following example appears on the screen, and the memory test begins.

2. During the memory test, hit the Pause key.
3. Verify the stepping version of the CPUs in the line similar to the following:
2 Processors Detected, CG - CG
4. To continue with the reboot, hit any key.
To verify the stepping version of your CPU(s) in a remote server:
1. Enable the Serial-Over-Lan(SOL) feature on the SP.
For more information, refer to the "Serial Over LAN" section in Chapter 5 of the Sun Fire V20z and Sun Fire V40z Servers--Server Management Guide (817-5249).
2. Launch an SOL session from a SP command-line interface (CLI) to connect to the platform console remotely.
platform set console -s sp -e -S baud rate
where baud rate is the value that you have set in the BIOS settings; the default baud rate in the BIOS settings is 9600.
For example, if the baud rate in your BIOS settings is set to the default value, you would enter:
platform set console -s sp -e -S 9600
|
Note - This command changes the baud-rate value for the SP so that it matches the baud rate in the BIOS settings. It does not change the baud rate in the BIOS settings. |
5. Verify that the correct baud rate appears in the Speed column. Using the example above, the output should appear as follows:
Rear Panel Console Redirection Speed Pruning Log Trigger
SP Console Enabled 9600 No 244 KB
6. Activate the SOL session by running the following command.
7. Create another SP session from the SP prompt.
8. Re-cycle the power on the platform OS by running the following command.
|
Note - Before you re-cycle the power, ensure that the platform OS has been shut down gracefully, or that the file system has been synchronized using the sync command. |
platform set power state cycle -W -f
9. In the SP SOL session that you launched in Step 1, you now see the output of the BIOS CPU step screen.
For a sample of this output, see Step 1 in the previous procedure on "Invalid Cross-Reference Format".
10. During the server's memory self-test, terminate the remote session in order to pause the screen:
11. Verify the stepping version of the CPUs in the line similar to the following:
2 Processors Detected, CG - CG
The following CPUs have been upgraded to stepping version "CG" and qualified for the Sun Fire
V20z server:
These CPUs require Sun's BIOS version 1.27.9 or later and other updated firmware components to be installed on the server.
The AMD CPU is shipped in a box that has the following AMD and Sun Microsystems part numbers printed on the side:
If the CPU box has these part numbers, you must install the updated Sun BIOS and firmware on the server for the new CPU to function properly.
Reboot your server. Once the server reboots, a text message appears; see the sample in Step 1 of the procedure Verifying the Stepping Version In a Local Server.
Ensure that, in the header of this text message, the System BIOS Revision indicates V1.27.9 or higher. If the BIOS version is lower than v1.27.9, you need to update the BIOS and firmware.
If necessary, you can download the updated Sun BIOS and firmware from the following site:
http://www.sun.com/servers/entry/v20z/downloads.html
To install BIOS and the other firmware components, follow the instructions in the ReadMe file that is found on the download page.
In the original release of the Sun Fire V20z server, there is a plastic guide on the motherboard for supporting a half-length PCI-X card. This support guide prevents you from installing a full-length PCI-X card in the PCI 1 (66 MHz) position.
In the updated release of the server, the guide has been removed. You can now install a full-length PCI-X card in this slot.
If you have an original release (chassis PN 380-0979) of the Sun Fire V20z server, you may receive as a Super CRU the updated release (chassis PN 380-1168) of the server.
If you want to install the Solaris 9 Operating System (OS) on an updated release of the Sun Fire V20z server, you must download a Solaris OS Install-Time Update (ITU) from the Web site. This ITU is required during OS installation.
The Solaris OS ITU is available from the product Web site:
http://www.sun.com/servers/entry/v20z/downloads.html
