簡介

本文檔介紹在託管StarOS虛擬網路功能(VNF)的Ultra-M設定中，替換此處提到的統一計算系統(Unified Computing System, UCS)伺服器中的故障元件所需的步驟。

雙列直插式記憶體模組(DIMM)更換拖把
FlexFlash控制器故障
固態驅動器(SSD)故障
可信平台模組(TPM)故障
Raid快取故障
Raid控制器/熱匯流排介面卡(HBA)故障
PCI Riser卡故障
PCIe介面卡Intel X520 10G故障
模組化主機板上區域網(MLOM)故障
風扇托架RMA
CPU故障

背景資訊

Ultra-M是經過預打包和驗證的虛擬化移動資料包核心解決方案，旨在簡化VNF的部署。 OpenStack是適用於Ultra-M的虛擬化基礎架構管理器(VIM)，包含以下節點型別：

計算
對象儲存磁碟 — 計算（OSD — 計算）
控制器
OpenStack平台 — 導向器(OSPD)

Ultra-M的高級體系結構及涉及的元件如下圖所示：

本文檔面向熟悉Cisco Ultra-M平台的思科人員，詳細介紹在伺服器進行元件更換時，在OpenStack和StarOS VNF級別需要執行的步驟。

附註：Ultra M 5.1.x版本用於定義本文檔中的過程。

MoP的工作流程

必要條件

備份

在更換故障元件之前，請務必檢查Red Hat OpenStack平台環境的當前狀態。建議您檢查當前狀態，以避免更換過程開啟時出現問題。通過這種更換流程可以實現這一點。

在進行恢復時，思科建議使用以下步驟備份OSPD資料庫：

[root@director ~]# mysqldump --opt --all-databases > /root/undercloud-all-databases.sql
[root@director ~]# tar --xattrs -czf undercloud-backup-`date +%F`.tar.gz /root/undercloud-all-databases.sql 
/etc/my.cnf.d/server.cnf /var/lib/glance/images /srv/node /home/stack
tar: Removing leading `/' from member names

此過程確保可以替換節點而不影響任何例項的可用性。此外，建議備份StarOS配置，尤其是要替換的計算/OSD計算節點承載控制功能(CF)虛擬機器(VM)時。

附註：如果伺服器是控制器節點，請繼續執行「」部分，否則繼續下一部分。

元件RMA — 計算/OSD — 計算節點

確定在計算/OSD — 計算節點中託管的VM

確定伺服器上託管的VM。可能發生兩種情況：

伺服器僅包含服務功能(SF)虛擬機器：

[stack@director ~]$ nova list --field name,host | grep compute-10
| 49ac5f22-469e-4b84-badc-031083db0533 |  VNF2-DEPLOYM_s9_0_8bc6cc60-15d6-4ead-8b6a-10e75d0e134d     |  
pod1-compute-10.localdomain    |

伺服器包含控制功能(CF)/彈性服務控制器(ESC)/元素管理器(EM)/Ultra自動化服務(UAS)組合VM:

[stack@director ~]$ nova list --field name,host | grep compute-8
| 507d67c2-1d00-4321-b9d1-da879af524f8 | VNF2-DEPLOYM_XXXX_0_c8d98f0f-d874-45d0-af75-88a2d6fa82ea | pod1-compute-8.localdomain     |
| f9c0763a-4a4f-4bbd-af51-bc7545774be2 | VNF2-DEPLOYM_c1_0_df4be88d-b4bf-4456-945a-3812653ee229     | pod1-compute-8.localdomain     |
| 75528898-ef4b-4d68-b05d-882014708694 | VNF2-ESC-ESC-0                                             | pod1-compute-8.localdomain     |
| f5bd7b9c-476a-4679-83e5-303f0aae9309 | VNF2-UAS-uas-0                                             | pod1-compute-8.localdomain     |

註：此處顯示的輸出中，第一列對應於通用唯一識別符號(UUID)，第二列為VM名稱，第三列為VM所在的主機名。此輸出的引數將在後續章節中使用。

正常斷電

案例1.計算節點僅承載SF VM

將SF卡遷移到備用狀態

登入到StarOS VNF並確定與SF VM對應的卡。使用從「識別在計算/OSD — 計算節點中託管的VM」部分識別的SF VM的UUID，並識別與UUID對應的卡：

[local]VNF2# show card hardware
Tuesday might 08 16:49:42 UTC 2018
<snip>
Card 8:
  Card Type               : 4-Port Service Function Virtual Card
  CPU Packages            : 26 [#0, #1, #2, #3, #4, #5, #6, #7, #8, #9, #10, #11, #12, #13, #14, #15, #16, #17, #18, #19, #20, #21, #22, #23, #24, #25]

  UUID/Serial Number      :  49AC5F22-469E-4B84-BADC-031083DB0533

檢查卡的狀態：

10: FC       4-Port Service Function Virtual Card    Standby        -

如果卡處於活動狀態，請將卡移至備用狀態：

  [local]VNF2# card migrate from 8 to 10

從ESC關閉SF VM

登入到與VNF對應的ESC節點並檢查SF VM的狀態：

[admin@VNF2-esc-esc-0 ~]$ cd /opt/cisco/esc/esc-confd/esc-cli
[admin@VNF2-esc-esc-0 esc-cli]$ ./esc_nc_cli get esc_datamodel | egrep --color "<state>|<vm_name>|<vm_id>|<deployment_name>"
<snip>
<state>SERVICE_ACTIVE_STATE</state>

                    VM_ALIVE_STATE</state>
<snip>

使用其VM名稱停止SF VM。（在「識別在計算/OSD — 計算節點中託管的VM」部分中註明的VM名稱）：

[admin@VNF2-esc-esc-0 esc-cli]$ ./esc_nc_cli vm-action STOP VNF2-DEPLOYM_s9_0_8bc6cc60-15d6-4ead-8b6a-10e75d0e134d

停止後，VM必須進入SHUTOFF狀態：

[admin@VNF2-esc-esc-0 ~]$ cd /opt/cisco/esc/esc-confd/esc-cli
[admin@VNF2-esc-esc-0 esc-cli]$ ./esc_nc_cli get esc_datamodel | egrep --color "<state>|<vm_name>|<vm_id>|<deployment_name>"

                    VM_SHUTOFF_STATE</state>

案例2.計算/OSD — 計算節點主機CF/ESC/EM/UAS

將CF卡遷移至備用狀態

登入到StarOS VNF並確定與CF VM對應的卡。使用從「標識節點中託管的VM」部分中標識的CF VM的UUID，並找到與UUID對應的卡：

[local]VNF2# show card hardware
Tuesday might 08 16:49:42 UTC 2018

  UUID/Serial Number      : F9C0763A-4A4F-4BBD-AF51-BC7545774BE2
<snip>

檢查卡的狀態：

[local]VNF2# show card table

 9: FC       4-Port Service Function Virtual Card    Active         No         
10: FC       4-Port Service Function Virtual Card    Standby        -

如果卡處於活動狀態，請將卡移至備用狀態：

[local]VNF2# card migrate from 2 to 1

從ESC關閉CF和EM VM

登入到與VNF對應的ESC節點並檢查VM的狀態：

[admin@VNF2-esc-esc-0 ~]$ cd /opt/cisco/esc/esc-confd/esc-cli
[admin@VNF2-esc-esc-0 esc-cli]$ ./esc_nc_cli get esc_datamodel | egrep --color "<state>|<vm_name>|<vm_id>|<deployment_name>"

<snip>

使用其VM名稱逐一停止CF和EM VM。（在「識別在計算/OSD — 計算節點中託管的VM」部分中註明的VM名稱）：

[admin@VNF2-esc-esc-0 esc-cli]$ ./esc_nc_cli vm-action STOP VNF2-DEPLOYM_c1_0_df4be88d-b4bf-4456-945a-3812653ee229

停止後，VM必須進入SHUTOFF狀態：

[admin@VNF2-esc-esc-0 ~]$ cd /opt/cisco/esc/esc-confd/esc-cli
[admin@VNF2-esc-esc-0 esc-cli]$ ./esc_nc_cli get esc_datamodel | egrep --color "<state>|<vm_name>|<vm_id>|<deployment_name>"

將ESC遷移到備用模式

登入到節點中託管的ESC並檢查它是否處於主狀態。如果是，將ESC切換到備用模式：

[admin@VNF2-esc-esc-0 esc-cli]$ escadm status
0 ESC status=0 ESC Master Healthy


[admin@VNF2-esc-esc-0 ~]$ sudo service keepalived stop
Stopping keepalived:                                       [  OK  ]

案例2.計算/OSD — 計算節點主機CF、ESC、EM和UAS

恢復UAS虛擬機器

檢查UAS VM在新星清單中的狀態並將其刪除：

[stack@director ~]$ nova list | grep VNF2-UAS-uas-0
| 307a704c-a17c-4cdc-8e7a-3d6e7e4332fa | VNF2-UAS-uas-0                                                 | ACTIVE | -          | Running     | VNF2-UAS-uas-orchestration=172.168.11.10; VNF2-UAS-uas-management=172.168.10.3
[stack@tb5-ospd ~]$ nova delete VNF2-UAS-uas-0
Request to delete server VNF2-UAS-uas-0 has been accepted.

要恢復autovnf-uas VM，請運行uas-check指令碼以檢查狀態。它必須報告錯誤。然後使用—fix選項再次運行，以重新建立缺失的UAS VM:

[stack@director ~]$ cd /opt/cisco/usp/uas-installer/scripts/
[stack@director scripts]$ ./uas-check.py auto-vnf VNF2-UAS

恢復ESC虛擬機器

從新星清單中檢查ESC VM的狀態並將其刪除：

stack@director scripts]$ nova list |grep ESC-1

[stack@director scripts]$ nova delete VNF2-ESC-ESC-1
Request to delete server VNF2-ESC-ESC-1 has been accepted.

在AutoVNF-UAS中查詢ESC部署事務，並在事務的日誌中查詢boot_vm.py命令列以建立ESC例項：

將boot_vm.py行儲存到shell指令碼檔案(esc.sh)，並使用正確的資訊（通常為core/<PASSWORD>）更新所有使用者名稱*****和密碼*****行。也需要移除-encrypt_key選項。對於user_pass和user_confd_pass，您需要使用格式 — username:密碼(示例- admin:<PASSWORD>)。

查詢URL，以便從running-configbootvm.py並將bootvm.py檔案獲取到autovnf-uas VM。在這種情況下，10.1.2.3是自動IT虛擬機器的IP:

登入到新的ESC並驗證備份狀態：

ubuntu@VNF2-uas-uas-0:~$ ssh admin@172.168.11.14
…
   ####################################################################

從ESC恢復CF和EM虛擬機器

從新星清單中檢查CF和EM VM的狀態。它們必須處於ERROR狀態：

[stack@director ~]$ source corerc
[stack@director ~]$ nova list --field name,host,status |grep -i err   
| 507d67c2-1d00-4321-b9d1-da879af524f8 | VNF2-DEPLOYM_XXXX_0_c8d98f0f-d874-45d0-af75-88a2d6fa82ea | None                                 | ERROR|

登入到ESC主伺服器，為每個受影響的EM和CF VM運行recovery-vm-action。耐心點。ESC會安排恢復操作，但可能在幾分鐘內不會發生。監控yangesc.log:

sudo /opt/cisco/esc/esc-confd/esc-cli/esc_nc_cli recovery-vm-action DO 
       
       

[admin@VNF2-esc-esc-0 ~]$ sudo /opt/cisco/esc/esc-confd/esc-cli/esc_nc_cli recovery-vm-action DO VNF2-DEPLOYMENT-_VNF2-D_0_a6843886-77b4-4f38-b941-74eb527113a8

登入到新EM並驗證EM狀態是否為up:

ubuntu@VNF2vnfddeploymentem-1:~$ /opt/cisco/ncs/current/bin/ncs_cli -u admin -C
admin connected from 172.17.180.6 using ssh on VNF2vnfddeploymentem-1
admin@scm# show ems

ID  SLA  SCM  PROXY
---------------------
2   up   up   up
3   up   up   up

登入到StarOS VNF並驗證CF卡是否處於備用狀態

處理ESC恢復失敗

如果ESC由於意外狀態而無法啟動VM，Cisco建議如何通過重新啟動主ESC執行ESC切換。ESC切換將需要大約一分鐘。在新的主ESC上運行指令碼「health.sh」，以檢查狀態是否為up。主ESC啟動VM並修復VM狀態。完成此恢復任務最多需要5分鐘。

您可以監控/var/log/esc/yangesc.log和/var/log/esc/escmanager.log。如果您在5-7分鐘之後沒有看到虛擬機器被恢復，則使用者將需要執行受影響虛擬機器的手動恢復。

自動部署配置更新

在AutoDeploy VM中，編輯autodeploy.cfg並用新伺服器替換舊計算伺服器。然後在confd_cli中載入替換。以後成功停用部署需要此步驟：

root@auto-deploy-iso-2007-uas-0:/home/ubuntu# confd_cli -u admin -C
Welcome to the ConfD CLI
admin connected from 127.0.0.1 using console on auto-deploy-iso-2007-uas-0

auto-deploy-iso-2007-uas-0(config)#load replace autodeploy.cfg

auto-deploy-iso-2007-uas-0(config)#commit
Commit complete.
auto-deploy-iso-2007-uas-0(config)#end

在配置更改後重新啟動 uas-confd和autodeploy服務：

root@auto-deploy-iso-2007-uas-0:~# service uas-confd restart
uas-confd stop/waiting
uas-confd start/running, process 14078

元件RMA — 控制器節點

預檢查

在OSPD中，登入控制器並驗證pc是否處於正常狀態 — 所有三個控制器聯機，Galera將所有三個控制器顯示為主控制器。

附註：健康的群集需要2個活動控制器，因此請檢驗其餘的兩個控制器是否處於聯機狀態且處於活動狀態。

將控制器群集移至維護模式

使用控制器上在待機狀態下更新的pc集群:

[heat-admin@pod1-controller-0 ~]$ sudo pcs cluster standby

再次檢查pc status，並確保pc群集已在此節點上停止：

此外，其他2個控制器上的pc狀態應將該節點顯示為備用。

從控制器節點更換故障元件

關閉指定伺服器的電源。要更換UCS C240 M4伺服器上有故障的元件，可從以下站點參閱步驟：

更換伺服器元件

開啟伺服器電源

開啟伺服器電源並驗證伺服器是否啟動：

[stack@tb5-ospd ~]$ source stackrc
[stack@tb5-ospd ~]$ nova list |grep pod1-controller-0
| 1ca946b8-52e5-4add-b94c-4d4b8a15a975 | pod1-controller-0  | ACTIVE | -          | Running     | ctlplane=192.200.0.112 |

登入受影響的控制器，使用unstandby刪除備用模式。驗證控制器是否與群集一起聯機，Galera將全部三個控制器顯示為主控制器。這可能需要幾分鐘時間：

[heat-admin@pod1-controller-0 ~]$ sudo pcs cluster unstandby

[heat-admin@pod1-controller-0 ~]$ sudo pcs status
