Chapter 11 CL2 (Common Level 2) Messages

The messages in this chapter are sent by Common Level 2 (CL2) modules. CL2 modules provide level-2 data link functions for SNAX Extended Facility (SNAX/XF) and SNAX Advanced Peer Networking (SNAX/APN). The subsystem ID displayed for these messages includes CL2 as the subsystem name.

NOTE: Negative-numbered messages are common to most subsystems. If you receive a negative-numbered message that is not described in this chapter, see Chapter 15.

S7011 LDEV ldev [I/O ADR:(cpu,chan,%ctlr,%unit)]

cpu

identifies the processor number.

chan

identifies the channel number.

ctlr

identifies the controller number.

unit

identifies the unit number.

Cause  For BITSYNC controllers (6203/6204/3604) or CLIP controllers (3650/3605): This error is usually caused by a timeout of a CIU-to-LIU bus (CLB) transmission, or a controller or channel problem. For SNAXLink controllers: An error has occurred on the specified device, and the input/output (I/O) retry did not succeed.

Effect  For SNAXLink controllers, the system waits until the problem is corrected.

Recovery  Check the rank and priority of the communications interface unit (CIU) controllers and correct any problems found. If necessary, save the information returned in this message, contact your service provider, and provide all relevant information as follows:

  • Descriptions of the problem and accompanying symptoms

  • Details from the message or messages generated

  • Supporting documentation such as Event Management Service (EMS) logs, trace files, and a processor dump, if applicable

If your local operating procedures require contacting the Global Mission Critical Solution Center (GMCSC), supply your system number and the numbers and versions of all related products as well.

S7011 LDEV ldev I/O ADR:(cpu,chan,%ctlr,%unit) LINE $line RETRY %dev-status %ctlr-err

cpu

identifies the processor number.

chan

identifies the channel number.

ctlr

identifies the controller number.

unit

identifies the unit number.

dev-status

contains the interrupt cause word. The interrupt cause word (RIC) is used by the communications interface unit (CIU) to report CIU or CIU-to-LIU bus (CLB) error conditions and to report the successful completion of input/output (I/O) operations. The interrupt cause word has two formats: one for input (reading) and one for output (writing). The interrupt cause word returned to the I/O channel during the interrupt sequence contains the controller-specific status information that forced the generation of an interrupt by the controller.

For a description of the interrupt cause word, refer to the table or figure that corresponds to the controller:

  • For BITSYNC controllers (6203/6204/3604), refer to Table 11-1.

  • For CLIP controllers (3650/3605), refer to Table 11-3.

  • For SNAXLink controllers and outbound interrupts, refer to Table 11-4.

  • For SNAXLink controllers and inbound interrupts, refer to Table 11-5.

ctlr-err

is a file‑system error. ctlr‑err is either 213 (octal for file-system error 139) or 336 (octal for file-system error 222).

Table 11-6 shows the interpretation of bits 8 through 15 of the interrupt cause word. Bits 8 and 9 are type bits; their value indicates how you should interpret the values in bits 10 through 15. Bits 10:15 indicate the actual interrupt cause.

Table 11-6 Interrupt Cause Word Bits 8:15 for SNAXLink Controllers for CL2 Message 5

Value of Bits 8:9Value of Bits 10:15Meaning
00 Operational interrupts, which indicate the result of an EIO instruction issued to the CIU controller. They are nonfatal; the CIU controller continues to function normally, and the unit generating the interrupt goes into an inactive state and awaits the next EIO instruction.
 %1Operation completed without error.
 %2Write operation terminated without any data being transferred across the SNAXLink link.
 %3The TX SNAXLink link controller aborted the frame being transferred across the SNAXLink link.

 %24The LOCS block checksum was not equal to the checksum calculated by the CIU controller during transfer to the CIU controller.
 %25The START EXECUTION EIO instruction specified a starting address that was not within the proper range ($D200 through $EFFF).

 %30The parameter word transferred with this EIO instruction is not supported on this unit.
 %31Reserved for future use.
 %32The NVRAM either was programmed incorrectly or was not programmed at all. It is impossible to return a valid identification block.
01 Microcode interrupts, which indicate that a failure in the microcode has been detected, either a software queue overflow or a state failure. They are fatal and are reported only on unit 0.  The CIU controller disables the SNAXLink link and all I/O channel activity.
 %0, %1, %2, %3, %4, %5, %6, %7, %11, %12, %13, %14, %15, %16, %20, %21, %22, %23.When bits 8:9 are set to 01 (microcode type interrupts), bits 10:15 indicate a microcode state failure or other microcode error. Contact your representative and be sure to include the contents of the RIC word in your service request.
10 Hardware interrupts, which indicate a hardware failure. They are fatal and are reported on unit 1. The CIU controller disables the SNAXLink link and all I/O channel activity. The hardware interrupt codes are documented in the 3840 SNAXLink Maintenance Manual.
11 Illegal interrupts should never be generated by the CIU controller. A cause word with bits 8 and 9 set indicates that the CIU controller malfunctioned in an undetectable manner. Shut down the CIU controller and contact your HP representative.

 

When GUARDIO message 100 is displayed for a SNAXLink line, the EIO status word (RDST) is returned for %dev-status in the TMDS FIND DETAIL ON command. The CIU controller returns this status code to indicate:

  • Whether or not it has accepted the EIO instruction

  • Whether or not it has been downloaded and is executing from the downloaded microcode

Figure 11-3 shows the format of the EIO status word.

Figure 11-3 IO Status Word Format

IO Status Word Format

Table 11-7 lists the meanings of the individual bits in the EIO status word.

Table 11-7 Bits in EIO Status Word for CL2 Message 5

BitMeaning
0Ownership error. The CIU controller received an EIO instruction on an I/O channel port that did not “own” the CIU controller. In such a case, the CIU controller discards all EIO instructions except for TAKEOWNERSHIP and KILLPORT.
1Interrupt bit. An EIO instruction has been directed to a CIU controller that has an interrupt pending in the port interface interrupt registers.
2Busy bit. The possible causes are as follows:
  • The CIU controller is busy executing another operation and can be interrupted only by a privileged EIO instruction.

  • The CIU controller is unable to accept any EIO instructions except TAKEOWNERSHIP, KILLPORT, and RESET.

  • The EIO queue is full.

  • The CIU controller received a PON, a front-panel reset on the owning I/O channel port.

  • A RESET or TAKEOWNERSHIP EIO received on the owning I/O channel port.

3A parity error was detected during transfer of the parameter word. The CIU controller discards the EIO instruction. If the error was detected during the transfer of a command word, the CIU controller is not selected and the I/O channel times out the EIO instruction. The CIU controller remains unaware of the EIO and subsequent timeout.
4The CIU controller is executing microcode out of its bootstrap EPROM.
5The CIU controller received an invalid EIO instruction.
6The CIU controller has been shut down because of a parity error or because the parity-checking circuitry was disabled.
7The CIU controller is performing or has failed a self-test. Self-tests occur after a PON, a front-panel reset, or a RESET EIO command.
8The CIU controller has enabled the SNAXLink link controllers.
9The CIU controller has set the SNAXLink link controllers into loopback mode.

 

Cause  This message is usually caused by a hardware error and applies to BITSYNC controllers (6203/6204/3604), CLIP controllers (3650/3605), and SNAXLink controllers.

  • For controllers other than SNAXLink controllers:

    After the CIU transfers a write data frame to a communications line interface processor/break-out board (CLIP/BOB) from the processor, the CIU times the wait-for-acknowledgment (WACK) response from the CLIP/BOB to which the frame was sent.

    If the response is timed out by the CIU, then an interrupt is generated to the appropriate communications access process/Communications Subsystem Manager (CAP/CSM) with a timed-out indication. The CIU suspends further transfers to the failing CLIP/BOB. To reactivate transfers to the CLIP/BOB, the CAP/CSM issues either a LINK CLEAR EIO or INITIATE WRITE EIO instruction with a retry parameter.

  • For SNAXLink controllers:

    An error occurred on the specified device.

Effect  The operation is retried.

Recovery  For controllers other than SNAXLink controllers, check the BOB and the CLIP modules.

For SNAXLink controllers, this is an informational message only; no corrective action is needed unless otherwise indicated in Table 11-6.

Cause  This message applies to the CLIP controllers (3650/3605) only. A request was issued to CL2, but no stations were configured. This request may also be caused by an invalid state action.

Effect  CL2 performs recovery; however, this recovery could stop all link protocol.

Recovery   If CL2 stops all link protocol, obtain a trace if you can replicate the problem, contact your service provider, and provide all relevant information as follows:

  • Descriptions of the problem and accompanying symptoms

  • Details from the message or messages generated

  • Supporting documentation such as Event Management Service (EMS) logs, trace files, and a processor dump, if applicable

If your local operating procedures require contacting the Global Mission Critical Solution Center (GMCSC), supply your system number and the numbers and versions of all related products as well.

Table 11-8 lists SNAXLink generated file-system errors. If the error is not listed in this table, refer to Appendix B.

Table 11-8 SNAXLink Generated File-System Errors for CL2 Message 100

%fs‑err1Meaning
0Operation was successful; no errors occurred.
11Download microcode file was not found.
31Unable to obtain memory (LOCALPOOL) needed by SNAX/XF.
33Unable to obtain memory (XPOOL) needed by SNAX/XF.
49Attempted to access a microcode file that had an invalid file code.
59Microcode file was invalid (that is, it contained a bad directory or a bad record count), or a bad condition code occurred during a read of the microcode file.
66The SNAXLink line was down, or the SNAXLink line was stopped and requests were aborted because of the stop.
73The SNAXLink CAU was inaccessible (locked up) because the SNAXLink key was in the OFFLINE position.
120SNAXLink encountered a fatal checksum error. This error generally represents an internal problem for which you should call your HP representative. Sometimes, however, the error is caused by the IBM channel cables exceeding 200 feet in length.
121Text underrun. Data late arriving at SNAXLink.
122Mode-setting reset command was received from SNAXLink, or a link error occurred.
139Fatal error in CIU controller, or the controller was reset to BOOT state.
160Request was invalid for current state, or an attempt was made to download the SNAXLink CAU but the AUTOLOAD option was OFF, or the incoming XID was invalid.
162Expected a response from SNAXLink and did not get one. Operation timed out.
164Mode-setting disconnect command received from SNAXLink. The physical unit (PU) is disconnected.When the IBM operator issues a VARY NET, INACT command for the PU or the SNAXLink Major Node, this is a normal condition. If no such command was issued, VTAM detected an error and declared SNAXLink inoperable. Check the console log, run an EREP report, and send the report and the error messages to your HP representative. This error is also caused by an IBM application sending more than 4096 bytes of data to the NonStop system.
169PU station undefined.
172Improper or invalid frame reply; or frame function, modifier, or length is invalid.
175An HDLC FRMR was sent or received by SNAX/XF. This internal error should be reported to your HP representative.
177Text overrun. Input frame exceeded maximum frame size.
179Active modeset occurred during information transfer state or disconnected state.
193Retries exhausted during an attempt to download microcode, or identification information from microcode file did not match information received from device, or verification of microcode downloaded failed, or microcode execution failed.
210Ownership changed during operation.
219A CIU-E was replaced with a CIU, but during system generation, product number 3841 was specified rather than 3840. This error occurs only on the VLX system.
224A controller problem occurred; either an I/0 operation issued to a CIU controller was rejected, or the CIU controller returned an error status.
230Processor powered down and up.
231CIU controller and/or SNAXLink CAU powered down and up, or a SNAXLink CAU reset occurred, or SNAX/XF detected a fatal error on the NonStop K-series system channel.
301A disk file error has occurred. %fserr2 is the specific file system error.

 

Effect  The controller cannot be used until the microcode is downloaded.

Recovery   Look at the file-system error code in the message. See Table 11-8 or to Appendix B, for a definition of the specified error. For more detailed information, including recovery actions, refer to the Guardian Procedures Errors and Messages Manual.
