PCI Card OL* Overview and Concepts WARNING Observe all safety precautions to avoid being injured while accessing systems to add or replace cards. CAUTION Observe all safety precautions prior to physically accessing the system to prevent static discharge from damaging the system. NOTE Certain “Classes” of hardware are not intended for access by users. At this time this includes V-Class and Superdome systems. HP recommends that these systems only be opened by a qualified HP Engineer.
PCI Card OL* Overview and Concepts Important Terms and Concepts Important Terms and Concepts Table 1-1 Term Terms and Meanings Meaning OL* All aspects of On-line Addition (OLA) and On-line Replacement (OLR) of PCI & PCI-X interface cards. On-line Delete (OLD) is not supported. Power Domain A grouping of 1 or more interface card slots that are powered on or off as a unit. Current systems have each slot in a separate power domain.
PCI Card OL* Overview and Concepts Planning and Preparation Planning and Preparation For the most part, these tools prevent you from performing OL* procedures that would adversely affect other areas of the server. This section provides you with important information that can help minimize errors or problems when performing OL* procedures. Card Compatibility Online Addition When adding an interface card online, the first issue that must be resolved is whether the new card is compatible with the system.
PCI Card OL* Overview and Concepts Planning and Preparation This is particularly important if there is no online fail-over or backup card to pick up those functions. For example: • Which mass storage devices will be temporarily disconnected when the card is shut down? • Will a critical networking connection be lost? A critical resource is one that could cause a system crash or loss of data if the slot were suspended or disconnected.
PCI Card OL* Overview and Concepts OL* Methods OL* Methods Each of the three methods has similarities and differences and a chapter is devoted to each method, as well as an additional chapter with flowcharts showing all of the methods together for comparison and to act as a quick reference. “Mixing OL* Methods” on page 88 includes a table, which details the consequences of mixing OL* methods.
PCI Card OL* Overview and Concepts OL* Methods • A Fast Web interface is light on the network and can be used in places where an X-Windows interface is not available or does not provide equivalent speed. • Additional Web Security provides a secure, encrypted connection between the Web browser and the host system. Attention Button OL* compatible slots feature an OLX Divider that contains a power LED, an attention LED, and an Attention Button.
PCI Card OL* Overview and Concepts Important Considerations Important Considerations This section presents other situations that you are likely to encounter when performing OL* operations, and how to handle them accordingly: • “Power Domains” • “Multi-port Cards” • “Virtual Ports” • “Firmware Patch Information” • “Shared Slots” • “Frequency Mismatch” Power Domains A power domain is a grouping of 1 or more interface card slots that are powered on or off as a unit.

4 olrad - Command Line Interface The olrad command provides the ability to perform online addition and replacement of I/O cards. olrad performs critical resource analysis of the system before performing any OL* operation. This is to ensure that the system is not left in an inconsistent state after a PCI card is added/replaced. Only users with root privileges may use this command. The olrad command replaces the rad command.
olrad - Command Line Interface Using olrad Using olrad Argument Description and Syntax The following arguments are used in the command. slot_id SLOT ID of an OLA/R capable slot. A slot ID is a list of one or more numbers separated by dashes. Each number represents a component of the physical location of the slot. The user can use the slot ID to locate the slot. The sequence of numbers in the slot ID is platform dependent. On N and L classes, the slot ID contains only the slot number.
olrad - Command Line Interface Using olrad The CRA severity levels and their meanings. CRA_SUCCESS no affected resources in use. CRA_WARNINGS resources in use on affected device(s) but none are deemed critical. CRA_DATA_CRITICAL probable data loss, only proceed with the user's permission. CRA_SYS_CRITICAL likely to bring down the user's system. CRA_ERROR some internal CRA error encountered. The syntax for this option is olrad -C slot_id. Example 4-2 CRA Reporting Success.

A Troubleshooting The following documents typical messages returned by the system.
Troubleshooting Messages from pdweb Actions Messages from pdweb Actions There are two types of messaging facilities provided by the Peripheral Device Tool: • Messages recording OL* activity and errors generated by commands executed by pdweb that are stored in various log files. • Error messages that occur within the Peripheral Device Tool and are displayed to the user.
Troubleshooting Messages from pdweb Actions • pg • more • cat The NetTL Log File The NetTL log file contains all errors generated by olrad except those that are generated when using view options such as -q or -c. This is a log file, not a directory. Where is the NetTL Log File Located The NetTL log file can be found in /var/adm/nettl.LOG00 How to View the NetTL Log File To view the NetTL log file, you will use the netfmt command.
Troubleshooting Messages from olrad Actions Messages from olrad Actions Logging olrad uses the NetTL subsystem to log errors and audit trail for all OL* operation performed on various slots. olrad makes use of the SYSADMIN subsystem formatter to format the log messages. The following details are not logged: • CRA report when performing OL*, • CRA report when using the -C option, • Output of view information options such as -v, -c, -g, -h, -q, and -n.
Troubleshooting hotplugd Daemon Diagnostics hotplugd Daemon Diagnostics Messages in the System Log File The following messages are logged in the system log file, /var/adm/syslog/syslog.log. If an Attention Button event occurs after the daemon has been terminated following a successful start of the daemon, the messages are logged in the system log file.
Troubleshooting hotplugd Daemon Diagnostics Messages in the hotplugd Daemon Log File The following messages are logged in the hotplugd daemon log file, defined by logfile. ioctl(DEV_OLAR_GET_ABEVENT/WAIT) error : errno = errMsg An error has occurred on the ioctl() call to get Attention Button events from the kernel in the WAIT mode. errMsg gives the reason for the error.
Troubleshooting hotplugd Daemon Diagnostics #oprnNum oprn - slot( slotId ) - time( time ) - Invalid PCI OL * operation hotplugd has received an invalid PCI OL* operation on slot slotId. oprn can be one of the following: INVALID, INVALID_INSERTION, INVALID_REMOVAL. time is the time at which the Attention Button was pressed. This could happen if INSERTION or REMOVAL is received and the slot is not in the right state.

Additional Resources Other documentation Other documentation The following documents available on http://www.docs.hp.com are related to OL* actions and may provide additional information. • HP System Partitions Guide: Administration for nPartitions • Writing a PCI OLAR Driver chapter in the 11.23 Driver Development Guide. • Managing Systems and Workgroups document in the System Administration section for the specific OS release version you are using.
C Advanced OL* Topics This chapter discuses various advanced topics related to OL*.
Advanced OL* Topics Attention Button Actions Attention Button Actions On pressing the Attention Button, the system would generate the POWER_OFF event under the following cases: a. Slot is occupied, no drivers are attached, AND the AB event is an “NORMAL_REMOVAL” event. b. Slot is occupied, drivers are attached to the slot, and the drivers are suspended, AND the AB event is an “NORMAL_REMOVAL” event. c.
Advanced OL* Topics Attention Button Events Attention Button Events The following are various Attention Button events: INSERTION_UNPOWERED Card inserted, slot unpowered INSERTION_POWERED Card inserted, slot powered NORMAL_REMOVAL Normal hot removal SURPRISE_REMOVAL Surprise removal, for example, the latch is opened when the power is ON FREQ_MISMATCH OL* failed because the frequency at which the card can operate is not compatible with the current bus frequency MODE_MISMATCH OL* failed because the
Advanced OL* Topics PCI OL* Events PCI OL* Events The following are the various PCI OL* events: HPD_OP_INVALID_REMOVAL could not map the NORMAL_REMOVAL AB event HPD_OP_INVALID_INSERTION could not map the INSERTION_POWERED or INSERTION_UNPOWERED AB event HPD_OP_ADD ADD operation HPD_OP_PRE_REPLACE pre-replace or suspend HPD_OP_POST_REPLACE post-replace or resume HPD_OP_SURPRISE_REMOVAL surprise removal has occurred HPD_OP_FREQ_MISMATCH frequency mismatch has occurred HPD_OP_MODE_MISMATCH bus-mode
Advanced OL* Topics OL* Driver Scripts OL* Driver Scripts At various stages throughout most OL* procedures, olrad may initiate certain actions that notify the system of the addition or replacement of an interface card. Since pdweb invokes olrad, these scripts are also run when using pdweb. The script name should be the same as the driver name.

See also OL* Affected Slots The set of PCI slots, other than the target slot, that would have their PCI bus disrupted as a result of a hot plug operation. This disruption includes anything that would interfere with bus traffic, including events like a bus reset or a loss of bus power.
