1.3 Determining If You Have a Front-Access or Rear-Access Model

If you are not sure whether you have a front-access or a rear-access model, go to the front of the chassis and look at the top part of the chassis.

■ If you see the DC connectors at the front of the chassis, then you have a front-

access model (

■ If you do not see DC connectors at the front of the chassis, and metal filler plates

fill the gaps where the DC connectors would normally be, then you have a rearaccess model ( for the rear-access model.

1.4 Determining If You Have AC- or DCPowered Servers and Chassis

All of the Netra CT servers installed in a chassis must be either AC or DC; do not mix AC- and DC-powered servers in the same chassis. Even though there are no differences in most of the components in the AC- and DC-powered servers (such as fans, boards, and drives), the differences in the power supplies and the power connectors restrict you from mixing AC- and DC-powered servers in the same chassis.

The label located between the two silver screws at the base of the each power supply unit tells you whether the servers in the chassis are all AC- or DC-powered (

1.5 FRU Categories

In general, the FRUs in a Netra CT server can be divided into two categories:

■ Hot-installable/replaceable (referred to hereafter as hot-swappable), meaning that

you can install or remove and replace a FRU while the server is running, without interrupting the operation of the server. This category of FRU sometimes requires that you enter hot swap software commands before and after an installation or a removal/replacement to incorporate the new FRU in the system correctly. For more information on the hot swap commands, refer to Chapter 5.

■ Non-hot swappable, or cold-swappable, meaning that you must halt (and, in some

cases, also power off) the server before installing or removing and replacing a FRU. Note that you must halt power only to the server where you would be removing and replacing the FRUs; any other servers installed in the same chassis can remain running.

Redundant power supplies and hard disk drives in a Netra CT 810 server are a variation of the hot-swappable category. You can replace a single power supply in a redundant configuration while the server is running, without having to enter any software commands, or a single hard disk drive after you have unmounted the drive or disengaged it if you are running a disk management software package.

1.5.1 Hot-Swappable FRUs

The FRUs listed below are hot-swappable:

■ I/O cards, both front-access and rear-access models

■ Satellite CPU cards

■ Alarm cards for both the Netra CT 810 server and the Netra CT 410 server

■ Alarm rear transition cards (rear-access model only)

■ Host CPU card

■ Host CPU front transition card (front-access model only)

■ Host CPU rear transition card (rear-access model only)

■ Either of the two hard disk drives in a Netra CT 810 server

■ DVD or DAT drives occupying the removeable media module

■ Fan trays

■ System status panels

■ System controller boards

■ Either of the two power supply units in a Netra CT 810 server

1. The alarm andalarm reartransition cardsare hot-swappableonly if the host CPUcard andsystem controller board are also installedin the Netra CT server.

2. The host CPUcard andthe host CPU front and rear transition cards are hot-swappableonly ifthe alarm card and systemcontroller boardare alsoinstalled in the Netra CTserver.

Powering the Server Off and On

This chapter gives instructions on powering the Netra CT server on and off.

■ Section 2.1, “Powering On the Server” on page 2-2

■ Section 2.2, “Powering Off the Server” on page 2-6

Note – Whenever you reboot or power your server on and off, the hot swap states

revert back to the default full hot swap state for all I/O slots. If you want basic hot swap on an I/O slot, you must manually reset the I/O slot to basic hot swap after rebooting or powering your server on and off.

Note – You can also power the Netra CT server on and off through the alarm card

using the poweroff and poweron commands. Refer to the Netra CT Server System Administration Guide for more information.

2-1

2.1 Powering On the Server

Note – You must have the host CPU card, alarm card and system controller board

installed in the Netra CT server before you can power it on; the server will not power on properly if all three of these components are not installed. Once the system is powered on and running, then you can hot-swap any of the three components as documented in this manual. Also, do not reboot the server if the alarm is in the process of resetting.

1. Verify that the power supply locking mechanism(s) on the server you are about to

power on are in the locked (), or down, positions.

FIGURE 2-1 shows the location of the power supply locking mechanisms on the Netra

CT server. Make sure you lock both power supplies if you are powering on a Netra CT 810 server.

6. Connect to the console and boot up the server.

Refer to Appendix B for instructions on connecting a terminal to your server, if necessary.

2.1.1 Verifying Full Power-Up

The Netra CT server may take several minutes to completely power up and finish the configuration process, depending on the number of I/O cards you have installed in the system. Do not remove or install any cards or components in the Netra CT server until you have verified that the system is completely powered up.

To verify that the system has been completely powered up and is fully configured, as root, enter:

# prtpicl -c fru -v | more

You should see output similar to the following:

chassis (fru, 3d00000008) :ChassisType SUNW,NetraCT-810 :State configured :_class fru :name chassis ...

■ If the entry in the State field is configured, then the system is completely

powered up and configured. You can safely remove and install boards and components at this point.

■ If the entry in the State field is not configured (for example, configuring or

unconfigured), then the system is still coming up. Do not remove or install any

cards or components in the Netra CT server in this state. You must wait several more minutes until the state goes to configured.

Chapter 2 Powering the Server Off and On 2-5

2.2 Powering Off the Server

You can power off the Netra CT server in three ways:

■ Graceful hardware power-down

■ Ungraceful hardware power-down

■ Graceful software power-down

If you do not have a terminal hookup to your server and your CPU is functioning normally, you should go through a graceful hardware power-down for your server. For a graceful hardware power-down, you would press the system power button for less than four seconds. This will start the orderly power-down sequence in a manner that no persistent OS data structures are corrupted. In the orderly power-down, applications in service may be abnormally terminated and no further services will be invoked by the CPU.

If you do not have a terminal hookup to your server and your CPU is not functioning normally, you will not be able to go through a graceful hardware powerdown; you will have to go through an ungraceful hardware power-down instead. For an ungraceful hardware power-down, you would press the system power button for more than four seconds. This will immediately shut the system down without making any attempts to keep the persistent OS data structures from being corrupted.

A graceful software power-down is a normal power-down using a terminal connected to your server, where you would log onto the server as root, then execute a software command to bring the server down safely.

■ For hardware power-down instructions, go to Section 2.2.1, “To Perform a

Hardware Power-Off” on page 2-6.

■ For software power-down instructions, go to Section 2.2.2, “To Perform a

Software Power Off” on page 2-7.

2.2.1 To Perform a Hardware Power-Off

1. In preparation for bringing down the operating system and powering off the server, ensure that all significant application activity is quiesced on the server.

2. Go to the front of the Netra CT server and locate the system status panel.

The location of the system status panels in the Netra CT 810 server and Netra CT 410 server is illustrated in

3. Locate the system power button on the system status panel.

FIGURE 2-2.

4. Press the system power button and release it to go through a graceful hardware power-down.

This will start the orderly power-down sequence in a manner that no persistent OS data structures are corrupted. In the orderly power-down, applications in service may be abnormally terminated and no further services will be invoked by the CPU. The system power LED will blink for several seconds, then it will go off.

5. Verify that the green power ( ) LED on the power supplies are blinking, indicating that the system is in the standby mode.

FIGURE 2-3 shows the system power LED location for the Netra CT 810 server, and FIGURE 2-4 shows the system power LED location for the Netra CT 410 server.

6. If you want to completely power off the Netra CT server, push the purple power supply unit locking mechanism(s) up into the unlocked ()position (

FIGURE 2-1).

Note – You must unlock the locking mechanism on both power supply unit(s) on the

Netra CT 810 server in order to completely power off that server.

The green power ( ) LED(s) on the power supply unit(s) should go off (unlit), indicating that the system is now completely powered off.

2.2.2 To Perform a Software Power Off

1. In preparation for bringing down the operating system and powering down the server, ensure that all significant application activity is quiesced on the server.

2. Log in as root at the system console and enter:

# cd / # shutdown -i0 -g0 -y

When the server is finished shutting down, the ok prompt is displayed.

3. Connect to the console and boot up the server.

CHAPTER

Handling Cards and Assemblies

This chapter gives instructions on how to safely handle the CompactPCI cards and assemblies. This chapter is divided into the following sections:

■ Section 3.1, “Handling CompactPCI Cards” on page 3-1

■ Section 3.2, “Handling Assemblies” on page 3-2

Consult the Netra CT Server Safety and Compliance Manual for safety information prior to performing the procedures in this chapter.

3.1 Handling CompactPCI Cards

Each Netra CT server in a chassis has a CompactPCI bus. All of the cards in a server—the CPU card, alarm card, and I/O cards—are CompactPCI cards.

Caution – The system is sensitive to static electricity. To prevent damage to the

assembly, always connect an antistatic wrist strap between you and the system.

Caution – Do not flex the CompactPCI cards; the surface-mounted components can

break if the card is bent.

To minimize the amount of card flexing, observe the following precautions:

■ When removing a card from an electrostatic discharge bag, keep it vertical until

you lay the card on the electrostatic discharge mat.

■ Do not place a card on a hard surface. Use a cushioned antistatic mat. The card

connectors and components have very thin pins that bend easily.

■ Be careful of small parts located on the component side of a card.

3-1

■ Do not use an oscilloscope probe on the components. The soldered pins are easily

damaged or shorted by the probe point.

■ Transport a card in an antistatic bag.

Caution – The heat sinks on a card can be damaged by incorrect handling. Do not

touch the heat sinks while installing or removing a card. Hold a card only by the edges. If a heat sink is loose or broken, obtain a replacement card.

Caution – The heat sinks on a card can be damaged by improper packaging. When

storing or shipping a card, ensure that the heat sinks have sufficient protection.

Caution – The system controller card and its modules have surface-mount

components that can be broken by flexing the card.

3.2 Handling Assemblies

Assemblies have their own set of handling requirements, similar to the requirements for CompactPCI cards.

Caution – The system is sensitive to static electricity. To prevent damage to the

board, always connect an antistatic wrist strap between you and the system.

4-12 Netra CT Server Service Manual • January 2004

4.3 Troubleshooting the System Using Diagnostic Software

There are several software packages that allow you to run diagnostic tests on your system, such as Sun VTS. SunVTS is a validation test suite that is provided as a supplement to the Solaris operating environment. The individual tests can stress a device, system or resource so as to detect and pinpoint specific hardware and software failures and provide users with informational messages to resolve any problems found. SunVTS runs at the operating system level.

There are several tests that are particularly useful when troubleshooting a Netra CT server:

■ alarm2test—alarm2test is part of SunVTS, but it is used specifically to test

the alarm card installed in the Netra CT server by invoking the alarmdiag test on the alarm card. alarm2test runs at the operating system level.

■ obdiag—obdiag is similar to the alarm2test, in that it invokes the

alarmdiag test on the alarm card; however, obdiag is run from the firmware level, not the operating system level.

■ Apost—Apost is part of the Chorus operating system image on the alarm card. It

runs a basic test on the alarm card to verify that the alarm card is operating properly before bringing up Chorus on the alarm card.

A new utility called diagconf, which is also part of the Chorus operating system image on the alarm card, is now available. You can use diagconf to set or display the configuration settings for Apost, allowing you to make the tests run on the alarm card more or less thoroughly before the Chorus operating system is brought up on the alarm card.

To display the values currently set for Apost, access the alarm card command line interface (CLI), and, through the alarm card CLI, enter the following command:

hostname cli> diagconf -d

Chapter 4 Troubleshooting the System 4-13

You should see output similar to the following, giving you the values currently set for the Apost test on the alarm card:

diag-switch False verb-mode True stop-on-error False diag-level Max mfg-mode Off hdr-checksum 0xaa time-stamp 0 record-format-ver 49 post-version 02 reset-status 0xd0000000 post-status ... post-msg Watchdog Reset-------- POST Passed-------------------

Some values are hard-set and cannot be changed by a user, while others can be changed to make that particular test more or less thorough. To change the value for a particular test, enter the following command:

hostname cli> diagconf -s command value

where command is the name of the command that you want to change, and value is the value you want to change.

The following table lists the Apost tests that can be changed by a user and the allowable values for each. Any tests not listed in

TABLE 4-6 are either hard-set and

cannot be changed, or should not be changed by a user.

TABLE 4-6 Apost Tests and Values through diagconf

Command Value

diag-switch • True—Turns the diag-switch test on.

• False—Turns the diag-switch test off.

verb-mode • True—Turns the verb-mode test on.

• False—Turns the verb-mode test off.

stop-on-error • True—Stops the Apost testing when the first error is encountered.

• False—Continues Apost testing, regardless of the number of errors encountered.

diag-level • Off—Turns the diag-level test off.

• Min—Sets the diag-level test to the minimum level of testing.

• Max—Sets the diag-level test to the maximum level of testing

4-14 Netra CT Server Service Manual • January 2004

For more information on these and other tests in the SunVTS test suite, refer to the Computer Systems Release Notes Supplement for Sun Hardware document or the SunVTS documentation on the Solaris on Sun Hardware Answerbook, both included with your Solaris operating environment.

4.4 Troubleshooting the System Using the Power-On Self Test (POST)

When you first power-up the Netra CT server, some or all of the green Power LEDs on the system status panel will flash on and off for several seconds. The green Power LED for the I/O slot holding the CPU card (slot 1 in the Netra CT 810 server and slot 3 in the Netra CT 410 server) will go to solid green while the green Power LEDs for the remaining components are still flashing on and off; this is an indication that the CPU card has passed the power-on self test (POST).

Before any processing can occur on a system, it must successfully complete the POST. Messages are displayed for each step in the POST process. If there is a critical failure, the system will not complete POST and will not boot. To monitor this process, you must be connected to the TTY A port on the CPU card or CPU transition card. See Section 5.2.1, “Logging In to the Netra CT Server” on page 5-4.

OpenBoot PROM (OBP) variables control the console port. The variables and their possible settings are described below.

To see the console output device, enter:

ok printenv output-device

The screen will display something similar to the following:

output-device ttya

The possible settings for this variable are:

■ ttya (default)

■ ttyb

■ screen

■ rsc

Chapter 4 Troubleshooting the System 4-15

ttya and ttyb represent the serial ports on the CPU card. screen represents the display attached to the first frame buffer installed in the system (not present on the Netra CT server). rsc is used by the alarm card.

To see the console input device, enter:

ok printenv input-device

The screen will display something similar to the following:

input-device ttya

The possible settings for this variable are:

■ ttya (default)

■ ttyb

■ keyboard

■ rsc

ttya and ttyb represent the serial ports on the CPU card. keyboard represents the standard system keyboard (not present on the Netra CT server). rsc is used by the alarm card. If no system keyboard is connected, the console port defaults to ttya.

Note – Be sure the two variables are consistent with each other. For example, do not

set the output-device to screen and the input-device to ttya.

There is another OBP variable that controls the behavior of the POST process called diag-level. By default, this variable is set to max, which means POST will run more thorough/verbose tests against the hardware. This variable can also be set to min, which will run a less stringent set of tests against the hardware. A minimum level of POST testing also takes less time, so the Solaris operating environment can boot more quickly on a machine with diag-level set to min.

To run the maximum amount of POST tests, enter:

ok setenv diag-level max

To run the minimum amount of POST tests, enter:

ok setenv diag-level min

4.5 Troubleshooting the System Using the Alarm Card Software

For information on troubleshooting using the alarm card software, refer to the Netra CT Server System Administration Guide (816-2483-xx).

4.6 Troubleshooting a Power Supply Using the Power Supply Unit LEDs

There are two LEDs on each power supply unit: a green ( ) LED and an amber ( ) LED. You can use the LEDs on the power supply unit to troubleshoot each power supply unit; however, because there is one power supply unit in the Netra CT 410 server and two power supply units in the Netra CT 810 server, the actions to take are different.

4.6.1 Troubleshooting the Power Supply Unit in the Netra CT 410 Server

Following are the states of the LEDs on the power supply unit in the Netra CT 410 server:

■ Green, flashing—The power supply unit is in the standby mode; the power

supply unit is powered on, but it is not supplying power to the server.

■ Green, solid—Both the server and the power supply unit are powered on and

functioning properly.

■ Amber—A fault was found in the power supply unit. Replace the power supply

unit. See Section 10.5, “Power Supply Unit” on page 10-16 for those instructions.

■ Off—One of the following conditions apply:

■ The power supply locking mechanism is in the upper, unlocked position.

■ The accompanying cable is disconnected from the DC power distribution unit

or the AC power entry unit.

■ The accompanying power distribution unit has failed.

■ The power supply unit has failed.

Chapter 4 Troubleshooting the System 4-17

4.6.2 Troubleshooting the Power Supply Units in the Netra CT 810 Server

When both power supply units in a Netra CT 810 server are up and running properly, the green ( )LEDs on both power supply units will be ON (note that these are the LEDs on the power supply units themselves, not the LEDs on the system status panel).

If a power supply unit fails, the amber ( ) LED on the power supply unit might light, depending on the type of failure that has occurred:

■ If a soft-fault occurs, such as a stuck fan or a temperature warning, you should get

a notification of the error; however, the amber ( ) LED on the power supply unit will not light for a soft-fault condition. The power supply unit is still supplying power to the system during a soft-fault condition.

■ If a hard-fault occurs, such as a voltage problem, you should get a notification of

the error. In addition, the amber ( ) LED on the power supply unit does light for a hard-fault condition. The power supply unit does not supply power to the system during a hard-fault condition.

If one power supply unit fails (either a soft-fault or a hard-fault), but the other power supply unit is still functioning normally, you should replace the faulty power supply unit as soon as possible to keep the system up and running. If both power supply units fail, the action you should take varies depending on which of the two types of fault has occurred:

If Then

Both power supply units go through a soft-fault Replace one power supply unit at a time in

One power supply unit goes through a soft-fault and the other power supply unit goes through a hard-fault

Both power supply units go through a hard-fault The system is down and you should

4-18 Netra CT Server Service Manual • January 2004

order to keep the system up and running.

Replace the power supply unit that has gone through a hard-fault first in order to keep the system up and running.

replace at least one of the power supply units to bring the system back up again.

4.7 Troubleshooting a CPU Card

This section describes how to troubleshoot problems related to the CPU card. The information provided here primarily covers those situations when the system containing the CPU card does not boot up or when the CPU card is not fully functional after boot up. Only general troubleshooting tips are provided here. No component level troubleshooting information is included in this section.

The following topics are covered:

■ General troubleshooting tips

4.7.1 General Troubleshooting Tips

Caution – High voltages are present in the Netra CT server. To avoid physical

injury, follow all the safety rules specified in the Netra CT Server Safety and Compliance Manual when opening the enclosure and/or removing and installing the

board.

The following general troubleshooting tips are useful in isolating the problems related to the CPU card:

1. Make sure the CPU card is installed properly in the correct slot in the Netra CT server.

The CPU card should be installed in slot 1 in the Netra CT 810 server and in slot 3 in the Netra CT 410 server.

Chapter 4 Troubleshooting the System 4-19

2. Make sure all the necessary cables are attached properly to the CPU transition card.

The following figures show the connectors on the different CPU transition cards:

■ CPU front transition card, Netra CT 410 server—FIGURE 4-6

■ CPU rear transition card—FIGURE 4-7

Chapter 4 Troubleshooting the System 4-21

4.7.3 Mechanical Failures

Symptom

Unable to insert the CPU card into the backplane.

Action

1. Verify that there are no mechanical and physical obstructions in the slot where the CPU card is going to be installed.

2. Make sure no pins on the board connectors or the CompactPCI backplane connectors are bent or damaged.

4.7.4 Power-On Failures

This section provides examples of power-on failure symptoms and suggested actions. There can be several reasons for the power-on failures.

● Make sure the CPU card is installed properly.

Note – If both Ready and Alarm LEDs on the CPU card are green, the board is

partially functional and capable of running POST (power on self-test). It means that the basic functionality of the board is present. If none of the aforementioned LEDs is green, and the board is installed properly, the board is not functional. In that case, contact your Sun supplier or field service engineer.

4.7.5 Failures Subsequent to Power-On

Symptom

Cannot connect successfully to a TTY serial port; there are no POST messages and unable to send keyboard input.

Action

1. Check the TTY cable for proper setup.

4-22 Netra CT Server Service Manual • January 2004

2. If you do not see any output after connecting the TTY terminal to the CPU transition card, remove it and connect it to the COM port of the CPU card and try again.

4.7.6 Troubleshooting During POST/OBP and During Boot Process

This section describes certain possible problems encountered while running POST and OBP and during the boot process.

Symptom

POST error message displays:

cannot establish network service

Action

● This might be a hardware address problem. Add or check the media access control

(MAC) address to the server and the IP address at the server.

Symptom

POST detects Ecache error and a message similar to the one below is displayed:

STATUS =FAILED TEST =Memory Addr w/ Ecache SUSPECT=U5201 and U5202 MESSAGE=Mem Addr line compare error addr 00000000.00000000 exp 00000000.00000000 obs 88888888.88888888

Action

● This might be a mounting issue with the CPU Mylar film, socket, or heatsink

which could have occurred during transportation or due to severe vibration. Contact Sun s Enterprise Services Solution Center.

Chapter 4 Troubleshooting the System 4-23

Caution – Any attempt to disassemble or replace the aforementioned devices will

void the warranty.

4.7.7 OpenBoot PROM On-Board Diagnostics

There are several OBP variables specific to the Netra CT server, such as:

■ pcia-probe-list—Probes the bus that runs the first ethernet port (front

connection) and standard I/O devices (by default: 1, 2)

■ pcib-probe-list—Probes the bus that runs the second ethernet port (rear

connection) (by default: 1, 2, 3)

■ cpci-probe-list—Probes the bus that runs connections to all cPCI slots in the

ct400 or ct800 (by default: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, a, b, c, d, e, f)

The following section describes the OBP on-board diagnostics. To execute the OBP on-board diagnostics, the system must be at the ok prompt. The OBP on-board diagnostics are listed as follows:

■ watch-clock

■ watch-net and watch-net-all

■ probe-scsi

■ test alias name, device path, -all

4.7.7.1 watch-clock

The watch-clock command reads a register in the NVRAM/TOD chip and displays the result as a seconds counter. During normal operation, the seconds counter repeatedly increments from 0 to 59 until interrupted by pressing any key on the PS/2 keyboard. The following identifies the watch-clock output message.

Hot Swap Software Commands

5.1 Understanding Hot Swap

Certain FRUs in the Netra CT server are hot-swappable (see Section 1.5.1, “Hot-

Swappable FRUs” on page 1-7). Hot swap, a key feature of the PICMG standard,

means that a CompactPCI card that meets the PICMG standard can be reliably inserted into or extracted from a powered and operating CompactPCI platform without affecting the other functions of the platform.

The Netra CT system has hot-swap modes shown in

TABLE 5-1 Netra CT System Hot-Swap Modes

Type of Hot Swap Description

Basic The hardware connection/disconnection process is performed

automatically by the hardware, while the software connection process requires user assistance through the cfgadm (1M) command

Full Both the hardware and the software connection process are

performed automatically

High Availability High availability hot swap provides the ability to control the

hardware connection process. This provides a higher degree of control than just indicating insertion and extraction of a board. The hardware connection process is controlled by software on high availability systems, such as the Netra CT server

TABLE 5-1.

5-1

The Netra CT system is configured for full hot swap by default. You can change the mode of the slot for the CPU boards and I/O boards to basic or full hot swap using the cfgadm(1M) command. You might want to change the hot-swap state of a slot to basic, for example, if you need to insert or remove a third-party I/O board that does not have full hot-swap support.

Note that whenever you reboot or power your server on and off, the hot-swap states revert back to the default full hot-swap state for all I/O slots.

5.1.1 How High Availability Hot Swap Works

By default, the Netra CT server is configured to accept any cPCI FRU unless you specifically set an allowable plug-in for a specific slot (refer to the Netra CT Server System Administration Guide for more information.)

When a board is inserted into the Netra CT server, the alarm card checks the midplane FRU ID information for allowable FRUs for that slot, then checks the inserted board’s FRU ID to make sure the board is allowed in the particular slot. If the board is allowed in the slot, the alarm card powers up the board. If the board is not allowed in the slot, the alarm card sends an SNMP trap to the MOH application.

If a host or satellite CPU board is in use, that is, has applications currently running, the alarm card CLI power commands, such as poweron or poweroff, will not work for that CPU board.

5.1.2 Hot Swap with Boards That Don’t Support Full Hot Swap

You might want to change the hot-swap state of a slot from full to basic if you need to insert or remove a third-party I/O board that does not have full hot-swap support.

To determine the current hot-swap state of a slot, you use the prtconf(1M) command. To enable or disable a type of hot swap on a slot, you use the cfgadm(1M) command. For many cfgadm commands, you must know the attachment point ID for the I/O slot that you will be working on.

5.1.3 System Status Panel LED States and Meanings

The LEDs on the system status panel gives you information that will need to determine what state a board is in and whether it is safe to remove from the system. Refer to

5-2 Netra CT Server Service Manual • January 2004

TABLE 5-1 for more information.

Green Power LED state

TABLE 5-2 CompactPCI Board LED States and Meanings on the System Status Panel

Amber Okay to Remove LED state Meaning Action

Off Off The slot is empty or the system

thinks that the slot is empty because the system didn’t detect the card when it was inserted.

If there is a card installed in this slot, then one of the following components is faulty:

• the card installed in the slot

• the alarm card

• the system controller board Remove and replace the failed component to clear

down.

On Off The card is up and running. Do not remove the card in this state.

Off On The card is powered off. You can remove the card in this state.

Blinking On The card is powered on, but it is

offline for some reason (for example, a fault was detected on the card).

• Alarm card—You can remove the alarm card in this state.

• All other cards—Power off the slot through the alarm card software, then remove the card.

On On The card is powered on and is in

use, but a fault has been detected on the card.

Deactivate the card using one of the following methods:

• Use the cfgadm -f -c unconfigure command to deactivate the card. Note that in some cases, this may cause the system to panic, depending on the nature of the card hardware or software.

• Halt the system and power off the slot through the alarm card software, then remove the card.

The green Power LED will then give status information:

• If the green Power LED goes off, then you can remove the card.

• If the green Power LED remains on, then you must halt the system and power off the slot through the alarm card software.

Chapter 5 Hot Swap Software Commands 5-3

5.2 Using the cfgadm Utility

You can perform the following hot swap procedures using the cfgadm utility:

■ Deactivate and activate hot-swappable FRUs

■ Enable and disable full hot swap for I/O slots in a server

■ Enable and disable basic hot swap for I/O slots in a server

5.2.1 Logging In to the Netra CT Server

In order to use the cfgadm utility, you must be able to log in to the server either remotely, where you would log in to the Netra CT server as root through another server on the network, or directly, where you would connect a terminal console directly to your Netra CT server.

For more information on connecting a terminal console to your system, refer to

Appendix B.

5.2.2 Running the cfgadm Utility

For all cfgadm commands, you must know the attachment point ID for the I/O slot that you will be working on. To list the attachment point IDs for the I/O slots in a server, log into the server and, as root, enter the following command:

# cfgadm

For a Netra CT 810 server, you should get feedback similar to the following:

Ap_Id Type Receptacle Occupant Condition AL-8 mcd/fhs connected configured ok CPU bridge/fhs connected configured ok IO-2 stpcipci/fhs connected configured ok IO-3 unknown empty unconfigured unknown IO-4 stpcipci/fhs connected configured ok IO-5 unknown disconnected unconfigured ok IO-6 unknown empty unconfigured unknown IO-7 unknown empty unconfigured unknown

5-4 Netra CT Server Service Manual • January 2004

For a Netra CT 410 server, you should get feedback similar to the following:

Ap_Id Type Receptacle Occupant Condition AL-1 mcd/fhs connected configured ok CPU bridge/fhs connected configured ok IO-2 unknown disconnected unconfigured unknown IO-4 stpcipci/fhs connected configured ok IO-5 stpcipci/fhs connected configured ok

The attachment point ID is shown in the first column of the readout; for example, the attachment point ID for I/O slot 2 in a Netra CT 810 server would be

IO-2.

To view the online help for cfgadm, as root, enter:

# cfgadm -h pci

You should get the following feedback:

PCI hotplug specific commands:

-x enable_slot ap_id [ap_id...]

-x disable_slot ap_id [ap_id...]

-x enable_autoconfig ap_id [ap_id...]

-x disable_autoconfig ap_id [ap_id...]

You can also view the man page for the cfgadm utility by entering man cfgadm at the prompt.

5.2.3 Basic and Full Hot Swap cfgadm Commands

The Netra CT servers are set to full hot swap by default. Full hot swap on an I/O slot means that you do not have to manually deactivate or activate the I/O card when replacing it in the server; those processes are handled automatically.

■ To determine the current hot swap state for all of the I/O slots in your Netra CT

server, go to “Determining the Current Hot Swap State” on page 5-6.

■ To change the default settings for one or more I/O slots in your Netra CT server

to basic hot swap, go to “Enabling Basic Hot Swap on I/O Slots” on page 5-7.

■ To change the settings for one or more I/O slots in your Netra CT server back to

full hot swap, go to “Enabling Full Hot Swap on I/O Slots” on page 5-8.

Chapter 5 Hot Swap Software Commands 5-5

5.2.3.1 Determining the Current Hot Swap State

To determine the current hot swap state for the I/O slots, as root, enter:

# prtconf -v -P

For a Netra CT 810 server, the output is similar to the following:

cphsc, instance #0 System properties: name=’instance’ type=int items=1 value=00000000 name=’default-hotswap-mode’ type=string items=1 value=’full’ Driver properties:

name=’AL-8-autoconfig’ type=string items=1 dev=none

value=’enabled’

name=’IO-7-autoconfig’ type=string items=1 dev=none

value=’enabled’

name=’IO-6-autoconfig’ type=string items=1 dev=none

value=’enabled’

name=’IO-5-autoconfig’ type=string items=1 dev=none

value=’enabled’

name=’CPU-autoconfig’ type=string items=1 dev=none value=’enabled’ name=’hotswap-mode’ type=string items=1 dev=none value=’full’

■ If you see value ’basic’ underneath the default-hotswap-mode line, then

all of the I/O slots in the Netra CT server have been set to basic hot swap. You should see value ’disabled’ for every I/O slot in the system in this situation.

■ If you see value ’full’ underneath the default-hotswap-mode line, then at

least one of the I/O slots in the Netra CT server has been set to full hot swap. You

must look at the entries for individual I/O slots to determine if they have been set to basic or full hot swap mode in this situation:

■ If you see value ’enabled’ underneath a <slot#-autoconfig> line, then

that slot is set to full hot swap.

5-6 Netra CT Server Service Manual • January 2004

■ If you see value ’disabled’ underneath a <slot#-autoconfig> line,

then that slot is set to basic hot swap.

5.2.3.2 Enabling Basic Hot Swap on I/O Slots

All of the I/O slots in the Netra CT server are set to full hot swap by default. You can disable full hot swap on one or more I/O slots, bringing those slots to a basic hot swap state. That means that if an I/O card becomes faulty and needs replacing, you must manually deactivate the I/O slot using the cfgadm utility before you can remove the card, and then manually reactivate the I/O slot after replacing the card.

If you want to disable full hot swap on one or more I/O slots, bringing those slots to a basic hot swap state, as root, enter:

# cfgadm -x disable_autoconfig ap_id

Note – Whenever you reboot or power your server on and off, the hot swap states

revert back to the default full hot swap state for all I/O slots. If you want one or more I/O slots set to the basic hot swap setting, you must manually reset the I/O slots after rebooting or powering your server on and off.

Deactivating a Hot Swappable FRU

To deactivate an I/O card in a basic hot swap state, as root, enter:

# cfgadm -c unconfigure ap_id

where ap_id is the attachment point ID. For example, to deactivate an I/O card in slot 4, as root, enter:

# cfgadm -c unconfigure IO-4

Chapter 5 Hot Swap Software Commands 5-7

Reactivating a Hot Swappable FRU

To connect an I/O card, as root, enter:

# cfgadm -c connect ap_id

where ap_id is the attachment-point ID.

To activate an I/O card, as root, enter:

# cfgadm -c configure ap_id

where ap_id is the attachment point ID.

5.2.3.3 Enabling Full Hot Swap on I/O Slots

If you changed the hot swap states for one or more I/O slots from the default full hot swap setting to the basic hot swap setting, you can change use the cfgadm utility to change the I/O slots back to the default full hot swap setting.

To enable full hot swap for an I/O slot in a Netra CT server, as root, enter:

# cfgadm -x enable_autoconfig ap_id

where ap_id is the attachment point ID in the server that you want to have full hot swap enabled on. For example, to enable full hot swap for I/O slot 4, as root, you could enter the following:

# cfgadm -x enable_autoconfig IO-4

You can also enable full hot swap on all slots at once by rebooting the server, which automatically reverts back to the default full hot swap setting for all I/O slots.

CHAPTER

Removing and Replacing HotSwappable Cards

Caution – If you are just powering on your Netra CT server, do not remove or

install any cards in the system until you have verified that the system is completely powered up. Refer to Section 2.1.1, “Verifying Full Power-Up” on page 2-5 for more information.

Caution – An energy hazard is present if any I/O slots are left uncovered. If you

remove a card from an I/O slot, you must fill it with either a replacement card or a filler panel.

Note – Consult the Netra CT Server Safety and Compliance Manual and Chapter 3 of

this document for safety and board-handling information prior before performing the procedures in this chapter.

There are three types of cards that are hot-swappable in the Netra CT server:

■ Main cards—Following are the main cards that are available for the Netra CT

servers:

■ Host CPU card

■ Alarm card

■ Satellite CPU cards

■ I/O cards

The procedures for removing and replacing these cards are given in Section 6.1,

“Main Cards” on page 6-2.

1. The host CPUcard ishot-swappable only if the alarmcard andsystem controllerboard arealso installed in the NetraCT server.

2. The alarm card ishot-swappable onlyif the host CPU cardand systemcontroller boardare alsoinstalled in the NetraCT server.

■ Front transition cards—Following are the cards that provide connections to

standard I/O connectors on the front for front-access models:

■ Host CPU front transition card (Netra CT 410 server)

Note that the front transition cards are only hot-swappable as long as the accompanying host CPU card has been removed first.

The procedures for removing and replacing these cards are given in Section 6.2,

“Front-Transition Card” on page 6-28.

■ Rear transition cards—Following are the cards that extend the ports from the

main cards to the rear for rear-access models:

■ Host CPU rear transition card

■ Alarm rear transition card

■ Satellite CPU rear transition cards

■ I/O rear transition cards

Note that the rear transition cards are only hot-swappable as long as the accompanying main card has been removed first.

The procedures for removing and replacing these cards are given in Section 6.3,

“Rear-Transition Cards” on page 6-31.

6.1 Main Cards

6.1.1 Rules and Restrictions for Hot-Swapping Main Cards

Before removing and replacing any of the main cards in your server, you must first understand all rules and restrictions involved. The following sections describe the rules and restrictions for the main cards:

■ Section 6.1.1.1, “General Rules and Restrictions for Hot-Swapping Cards” on

page 6-6

■ Section 6.1.1.2, “Rules and Restrictions for Hot-Swapping the Host CPU Card” on

page 6-7

■ Section 6.1.1.3, “Rules and Restrictions for Hot-Swapping the Alarm Card” on

page 6-8

6.1.1.1 General Rules and Restrictions for Hot-Swapping Cards

Following are the rules and restrictions you must understand before hot-swapping any card in the Netra CT server:

1. You must have the host CPU card, alarm card and system controller board

installed in the Netra CT server before you can hot-swap any I/O card or satellite CPU card.

2. You may not be able to perform a full hot-swap on any card if the card is in a

failed condition; you must perform a basic hot-swap in this case. To determine if a card has failed, verify that these LEDs are in following states:

■ Amber Okay to Remove LED on the system status panel is on

■ Green Power LED on the system status panel is on

If the card has failed, you must manually unconfigure the card before you can hot-swap it by entering the following commands:

# cfgadm -c unconfigure ap_id # cfgadm -c disconnect ap_id

where ap_id is the attachment-point ID listed in the first column. If the LED states continue to show a failed condition for the card, then you must

halt the system.

6-6 Netra CT Server Service Manual • January 2004

3. You can only remove a card if all of these LEDs are in the following states:

■ Amber Okay to Remove LED on the system status panel is on

6.1.1.2 Rules and Restrictions for Hot-Swapping the Host CPU Card

Following are the rules and restrictions you must understand before hot-swapping a host CPU card:

1. You must have the alarm card and system controller board installed in the Netra CT server before you can hot-swap the host CPU card.

2. When you remove a host CPU card from a server while the server is running, it will disable the CompactPCI bus, which means that the connection with all I/O cards installed in the server will be lost. Once the CompactPCI bus is disabled, MCNet will also become disabled in the system.

After you install the host CPU card back into the server, it will enable the CompactPCI bus and will attempt to connect to all occupied card slots.

Satellite CPU cards are unaffected by the disabling of the CompactPCI bus; they will continue to function as stand-alone processors when you hot-swap a host CPU card.

3. If the host CPU is at the OpenBoot prompt (the ok prompt) and you want to hotswap the host CPU card, you must power off the host CPU slot through the alarm card.

To power off the host CPU slot in a Netra CT server, access the alarm card and, through the alarm card command line interface, enter:

cli> poweroff host

Refer to the Netra CT Server System Administration Manual for more information on accessing the alarm card.

Use the poweron command to power on the host CPU card once you’ve installed the replacement host CPU card.

4. If you are installing a Netra CP2140 host CPU board into a Netra CT server, do not change the default SMC module switch settings on the SW0501 switches. The Netra CT server supports high availability hot swap; however, because the alarm card controls the high availability on the Netra CT server, the settings on the

Chapter 6 Removing and Replacing Hot-Swappable Cards 6-7

SW0501 switches on the Netra CP2140 host CPU card should actually be set in the default, non-high availability settings. Refer to the Netra CT Server Product Overview for more information.

6.1.1.3 Rules and Restrictions for Hot-Swapping the Alarm Card

Following are the rules and restrictions you must understand before hot-swapping an alarm card:

1. You must have the host CPU card and the system controller board installed in the Netra CT server before you can hot-swap the alarm card.

2. You cannot hot-swap any other component in a Netra CT server while the alarm card is being hot-swapped.

3. You cannot install any new component into a Netra CT server while the alarm card is being hot-swapped.

6.1.2 Removing and Replacing Main Cards

The individual slots in your server will be set to full hot swap by default. You can also change the slots to basic hot swap manually. Refer to Chapter 5 for more information.

■ If you are removing and replacing a card in the server, first to go Section 6.1.2.1,

“Removing a Main Card” on page 6-8, then go to Section 6.1.2.2, “Inserting a Main Card” on page 6-17.

■ If you are installing a card in the server, go to Section 6.1.2.2, “Inserting a Main

Card” on page 6-17.

6.1.2.1 Removing a Main Card

Note – Do not proceed with these instructions until you have reviewed the

information in Section 6.1.1, “Rules and Restrictions for Hot-Swapping Main Cards”

on page 6-6. Failure to do so may result in an inadvertent system reboot or incorrect

configuration information.

1. Locate the card that you want to remove from the server.

FIGURE 6-1 shows the locations of these cards in the Netra CT 810 server. FIGURE 6-2

shows the locations of these cards in the diskfull Netra CT 410 server, and FIGURE 6-3 shows the locations of these cards in the diskless Netra CT 410 server.

2. Log into the Netra CT server.

Refer to Section 5.2.1, “Logging In to the Netra CT Server” on page 5-4, then return to this procedure.

3. Perform any necessary card-specific software commands.

■ If you are removing an alarm card from the server, you should make a record of

the settings that you have for the current alarm card so that you can use them on the replacement alarm card. Refer to the Netra CT Server System Administration Manual for instructions on displaying the settings that you have on the current alarm card. Make a record of those settings.

■ For any other card, there may be certain card-specific software commands that

you might have to perform before removing that hot-swappable card. Refer to the documentation that you received with the card for any card-specific procedures before proceeding with this procedure.

4. Determine the hot swap state for the slot that holds the card you are about to remove.

To determine the current hot swap state for the slots in your server, as root, enter:

# prtconf -v -P

The output is similar to the following (note that the following output is for a Netra CT 810 server; the output is similar for the Netra CT 410 server):

cphsc, instance #0 System properties: name=’instance’ type=int items=1 value=00000000 name=’default-hotswap-mode’ type=string items=1 value=’full’ Driver properties:

■ If you see value ’basic’ underneath the default-hotswap-mode line, then

all of the slots in the Netra CT server have been set to basic hot swap. You should see value ’disabled’ for every slot in the system in this situation. Go to

Step 5 on page 6-11 to manually disconnect the card before removing it.

■ If you see value ’full’ underneath the default-hotswap-mode line, then at

least one of the slots in the Netra CT server has been set to full hot swap. You must

look at the entries for individual slots to determine if they have been set to basic or full hot swap mode in this situation:

■ If you see value ’enabled’ underneath a <slot#-autoconfig> line, then

that slot is set to full hot swap. Go to Step 7 on page 6-12 to remove the card.

■ If you see value ’disabled’ underneath a <slot#-autoconfig> line,

then that slot is set to basic hot swap. Go to Step 5 on page 6-11 to manually disconnect the card before removing it.
