分析分級 Fretta 平台依賴 (PD) 問題

簡介

本文檔介紹如何在Fretta(NCS5500)系列路由器上分析和查詢平台相關問題的根本原因。 

要收集的日誌

對於任何與平台相關的診斷，請收集下列基本日誌。根據可疑的元件或功能區域，收集除基本日誌之外的其他日誌，如下面的小節所示。

要收集的基本日誌

• show logging
• show tech ctrace
• show tech card-manager
• show tech shelf-mgr
• show tech os
• show tech obfl

HeartBeat未命中日誌

• show tech heart-beat miss

EOBC/EPC相關日誌

請參閱跟蹤EOBC/EPC特定問題。

• show tech control-ethernet

光纖相關

• show tech fabric from xrvm

切片管理器

• 顯示技術支援sdr_mgr
• show tech-support install
• 顯示技術支援交換矩陣
• show tech-support fpd
• show tech-support cm
• show controller fabric health
• 顯示平台切片

MPA管理器

• show tech-support mpa-mgr

LED

• show tech-support env
• show tech-support alarm_mgr
• 顯示警報
• show led
• 顯示環境

詳細資料

使用card-mgr日誌進行分析

• 請花一些時間瀏覽卡管理器詳細維基，網址為 
• 若要調試任何平台問題，您需要使用show tech ctrace、show tech card-mgr和show tech shelf_mgr日誌來瞭解正在發生的情況。
• show reboot-history card location <> from shelf_mgr logs提供卡的重新啟動歷史記錄。
• show controllers card-mgr event-history brief location <>和show controllers card-mgr event-history detail location <>show tech card-mgr logs提供了有關card-mgr fsm狀態機詳細資訊的詳細資訊。
• 當卡無法啟動時，您需要檢視該卡的事件歷史記錄，並根據卡停滯/發生故障的狀態/事件檢查BIOS、PD安裝或card-mgr視點。每個事件都有一個關聯的郵遞區號，提供有關FSM運動的線索。

附註：如果線卡無法啟動並進入「失敗/失敗」狀態，則您需要在強制重新載入線卡後連線到線卡控制檯。這有助於您瞭解線卡無法啟動的原因。show tech無法從發生故障的線卡中收集日誌。

請參閱上面提到的card-mgr詳細wiki，瞭解特定狀態、事件和郵遞區號詳細資訊的含義。另請參閱calvados/dc_common_pkg/drivers/card_mgr/card_mgr_fsm.smil 上的card manager smil檔案。此檔案很好地描述了FSM狀態、事件和狀態轉換。

使用show tech ctrace進行離線分析

在Ads伺服器上離線解碼ctrace

1. 將show tech trace archive複製到ads伺服器上的目錄中。
2. 使用 — tar zxvf showtech-ctrace-admin-2019-Nov-06.174210.UTC.tgz取消歸檔內容
3. cd showtech-ctrace-admin-2019-Nov-06.174210.UTC
4. 使用此命令可以解碼目錄cmgr下的card_mgr進程的跟蹤：/users/gonaidu/bin/showtech_ct_dec -d cmgr -p card_mgr
5. cd cmgr

附註：ctrace解碼的日誌位於本地時區 — 如果已在班加羅爾ADS伺服器上進行解碼，則ctrace基於IST時區。在比較路由器日誌和離線解碼的ctrace日誌時，請牢記這一點。

確定主SC和主SUP

在cmgr目錄下使用「grep "Master Role" *":

card_mgr.0_RP0:299:2019-02-22:07.35.38.709224844:2580:calvados/dc_common_pkg/drivers/card_mgr/src/card_mgr_main.c:1539:main:cmgr_main:MAIN_HW_ARB_RESULT:[MAIN]: HW Arbitration Result = Master Role
card_mgr.0_SC0:96:2019-04-06:19.04.34.500975616:1976:calvados/dc_common_pkg/drivers/card_mgr/src/card_mgr_main.c:1539:main:cmgr_main:MAIN_HW_ARB_RESULT:[MAIN]: HW Arbitration Result = Master Role

從主SC檢索後代碼

 使用此命令獲取LC 0/1的郵遞區號：grep "slot 2" card_mgr.0_SC0 | grep changed

2019-04-06:19.04.34.759844864:1976:calvados/dc_common_pkg/drivers/card_mgr/src/card_mgr_interrupt.c:256:iofpga_check_card_post_code_change:cmgr_isr:ISR_CARD_POST_CODE_CHANGED:[ISR]: POST Code for slot 2 changed to 0xa0

主要RP視點中的事件歷史記錄：

grep RCAPI_NOTIFY_CARD_POST_CODE_CB card_mgr.0_RP0 | grep "0\/1" 

2019-04-06:19.04.40.665774834:2589:calvados/dc_common_pkg/drivers/card_mgr/src/card_mgr_rack_service.c:1919:cmgr_rack_notify_card_post_code_change_cb:cmgr_rack_capi:RCAPI_NOTIFY_CARD_POST_CODE_CB:[RACK CAPI]: 0/1 - CAPI cmgr_rack_notify_card_post_code_change_cb, client card_mgr (PID=1976,hdl=0x7f7c880ff728,slot=29)

如何拉動、編輯和建立Satori產品組合？

可以有多個行同時存在。工程師需要知道他/她應從何處獲取檢視。要瞭解適當的satori組合/devline，請從sysadmin linux提示符運行此命令

cat /etc/build-info.txt

你得到的輸出是這樣的

Before pulling the view, setup your environment

步驟2.確保此專案存在於git組態檔中，即；~/.gitconfig

[應用]

    空白= nowarn

    ignorewhitespace =更改

步驟3.在執行任何活動之前，使用此命令設定環境

source /auto/exr-yocto/tools/scripts/set_yocto_env

步驟4.使用此命令獲取檢視。

acme pull -sb ios_ena -dev cisco-xr-wr7 -plat none

步驟5.在shell中運行以下命令

取消設定CDPATH

用於構建核心的命令

步驟1.導航到satori目錄並運行此命令。

scripts/xr/build-release.sh -f

步驟2.成功構建核心後，它會將思科特定的修補程式應用到各種.c和.h檔案，並且代碼可在此路徑中用於代碼行走。

satori/target-n9000-gdb/bitbake_build/tmp/work/n9000_gdb-wrs-linux/

附註：您不應在此進行任何永久性更改以在二進位制檔案中反映出來，因為這是tmp位置，將在下一個生成中被覆蓋。此位置的代碼應用於代碼行走和.patch檔案生成。此處討論.patch檔案

從代碼位置角度來看，klm的代碼位於兩條路徑上

• 對於「代碼行走」和「修補程式生成」：

satori/target-n9000-gdb/bitbake_build/tmp/work/n9000_gdb-wrs-linux/

• 二進制/sdk生成中使用的實際.c和.h檔案

satori/meta-cisco-nxos/recipes-kernel/

在上述路徑上，您將獲得兩個目錄

A.cisco-klm —>這涵蓋模組化和固定式fretta系統中使用的所有klm。

B.cisco-klm-zermatt —>這涵蓋所有klm，它們僅用於固定的fretta系統，例如klm_iofpga。

如何對不同的klms進行更改並進行編譯？

對klm_iofpga進行更改非常簡單。只需轉到此路徑，即可開始對您感興趣的.c或.h檔案進行更改。

satori/target-n9000-gdb/bitbake_build/tmp/work/n900_gdb-wrs-linux/cisco-klm-zermatt/0.1-r0/klm_iofpga

為其他所有klm進行更改會有些棘手。如上所述，您需要轉到tmp位置，進行更改，生成.patch文件(如何生成.patch文件，將在此處介紹)。 將.patch檔案復制到特定位置，在.bb檔案中為這個新的.patch檔案建立條目並開始生成。

請找到進行更改的步驟。

步驟1.轉到要在其中進行更改的klm特定目錄。您會在此找到所有KLM。

satori/target-n9000-gdb/bitbake_build/tmp/work/n9000_gdb-wrs-linux/cisco-klm/0.1-r0

步驟2.使用面組工具進行更改，以便生成.patch檔案。請注意，此處的acme diff不起作用，因此您需要使用面組工具來生成修補程式檔案。

步驟3.設定面組工具別名

cd satori/target-n9000-gdb/bitbake_build/tmp/work/n9000_gdb-wrs-linux/cisco-klm/0.1-r0

alias quilt=/nobackup/rpanday/kernel-wr7/satori/target-n9000-gdb/bitbake_build/tmp/sysroots/x86_64-linux/usr/bin/quilt

quilt new patch_file.patch ->指令面組分配名為patch_file.patch的新.patch檔案。

面組頂部(quilt top)->此命令告知patch_file.patch位於面組堆疊的頂部並可供編輯。

面組編輯klm_obfl/obfl_dc3.c —->指令面組捕獲在klm_obfl/obfl_dc3.c中完成的更改。運行此命令後，obfl_dc3.c將開啟並可供編輯。編輯完成後，寫並退出。

面組刷新 —>此命令獲取已編輯檔案klm_obfl/obfl_dc3.c的差異，並將其放入patch_file.patch中。若要驗證相同內容，請在vi中開啟該檔案。

步驟4.生成修補程式檔案patch_file.patch後，將其複製到此路徑。

cp patches/patch_file.patch /nobackup/rpanday/kernel-wr7/satori/meta-cisco-nxos/recipes-kernel/cisco-klm/files

步驟5.在.bb檔案中為此新的.patch檔案建立一個條目。.bb檔案位於此位置。

/nobackup/rpanday/kernel-wr7/satori/meta-cisco-nxos/recipes-kernel/cisco-klm/cisco-klm_0.1.bb
