恢復MDS9000引導載入程式提示
簡介
本文說明如何從開機載入器提示和開機模式中復原多層資料中心交換器(MDS)。
必要條件
需求
思科建議您瞭解以下主題：
- MDS9000 CLI配置命令
- 如何設定與MDS交換機的控制檯連線。
- 如何設定MDS交換機或通過其管理埠將其連線到網路。
- 熟悉TFTP。
採用元件
本文檔中的資訊基於軟體要求版本6.2(9)及更高版本。本文檔使用的是支援12到48個線速16 Gbps光纖通道埠的MDS9148S交換機，即交換機名稱tempest。
本文中的資訊是根據特定實驗室環境內的裝置所建立。文中使用到的所有裝置皆從已清除（預設）的組態來啟動。如果您的網路運作中，請確保您瞭解任何指令可能造成的影響。
背景資訊
為了正常工作，MDS交換機需要有效的未損壞的Kickstart和系統映像才能完全啟動。無效、損壞或缺少Kickstart映像會阻止交換機啟動並在啟動載入程式提示符處停止。具有有效Kickstart映像，但系統映像無效或丟失的交換機最終處於引導模式。
交換機啟動順序
BIOS > Loader > Kickstart Image > System Image
- 基本輸入輸出系統(BIOS)載入載入程式。
- 載入器將Kickstart映像載入到RAM中，並啟動Kickstart映像。
- 啟動映像載入並啟動系統映像。
- 系統映像讀取啟動配置檔案。

復原程式
從交換機控制檯會話。
載入器>
步驟1.下載交換機的Kickstart和System映像，並將其放入TFTP伺服器目錄中。
在本例中， TFTP伺服器的IP地址為10.104.204.100。
步驟2.配置交換機管理IP地址、子網掩碼及其預設網關。
Check config options in loader prompt using help option
loader> help
help - print online help
boot - Boot image
cmdline - <arguments>
dir - List Directory
help - print online help
network - Set network communication settings
reload - Reboot the board.
serial - Set serial console settings
show - Show loader configuration
loader> net --ip=10.66.78.80 --nm=255.255.255.128 --gw=10.66.78.4
在此範例中：
- 交換機介面mgmt0 IP地址為10.66.78.80 255.255.255.128
- 交換機預設網關IP地址為10.66.78.4
或
對於交換機硬體型號，載入程式提示符中的IP分配語法略有不同。
此處列出的示例適用於T&V系列交換矩陣交換機。
loader> set ip 10.66.78.80 255.255.255.128
loader> set gw 10.66.78.4
附註：如果第一次啟動交換機（對於RMA交換機）或交換機已進行寫擦除啟動，則需要步驟2配置。
步驟3.啟動位於TFTP伺服器目錄中的Kickstart映像，將交換器進入開機模式。

步驟4.從啟動模式中恢復交換機。
1.檢查交換機引導提示符中的IP配置。
switch(boot)# sh ip
ip routing is disabled
Management Interface: ip address 10.66.78.80/25
ip default-gateway 10.66.78.4
如果未找到IP配置，請再次配置介面管理IP地址和預設網關IP地址，如下所示。
switch(boot)# config t Enter configuration commands, one per line. End with CNTL/Z. switch(boot)(config)# interface mgmt 0 switch(boot)(config-if)# ip address 10.66.78.80 255.255.255.128 switch(boot)(config-if)# no shut switch(boot)(config-if)# exit switch(boot)(config)# ip default-gateway 10.66.78.4 switch(boot)(config)# exit
-
測試TFTP伺服器和交換機之間的IP連通性（在載入程式提示符下ping響應不可用）。
從TFTP伺服器ping交換機管理IP地址。
C:\Users\mpandika> ping 10.66.78.80 Pinging 10.66.78.80 with 32 bytes of data: Reply from 10.66.78.80: bytes=32 time=2ms TTL=60 Reply from 10.66.78.80: bytes=32 time=3ms TTL=60 Reply from 10.66.78.80: bytes=32 time=3ms TTL=60 Reply from 10.66.78.80: bytes=32 time=3ms TTL=60 Ping statistics for 10.66.78.80: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 2ms, Maximum = 3ms, Average = 2ms C:\Users\mpandika>
- 將Kickstart和System映像從TFTP伺服器下載到交換機的bootflash。
switch(boot)# copy tftp://10.104.204.100/m9100-s5ek9-kickstart-mz.8.3.1.bin bootflash: Trying to connect to tftp server...... Connection to server Established. Copying Started..... TFTP get operation was successful Copy complete, now saving to disk (please wait)... switch(boot)# switch(boot)#copy tftp://10.104.204.100/m9100-s5ek9-mz.8.3.1.bin bootflash: Trying to connect to tftp server...... Connection to server Established. Copying Started..... TFTP get operation was successful Copy complete, now saving to disk (please wait)... switch(boot)#
4.驗證Kickstart映像和System映像是否成功下載到交換機的bootflash中。
switch(boot)# dir bootflash: 4096 Dec 22 2002 01:38:31 .partner/ 297 Nov 09 2017 07:18:54 MDS201711091818530370.lic 297 Nov 09 2017 07:28:42 MDS201711091828418770.lic 4096 Jul 23 2018 14:44:25 lost+found/ 26027008 Aug 08 2018 02:55:31 m9100-s5ek9-kickstart-mz.8.3.1.bin 109635731 Aug 08 2018 02:53:38 m9100-s5ek9-mz.8.3.1.bin 3430222 Feb 01 2000 02:31:30 moonlake.1.f.xsvf 23467 Jul 30 2018 12:40:56 mts.log 347607 Jul 28 2017 04:46:31 portchannel 4096 Dec 22 2002 02:38:54 scripts/ 31812 Jun 30 2018 05:07:27 snmp.pcap Usage for bootflash: filesystem 1264746496 bytes used 2106781696 bytes free 3371528192 bytes total switch(boot)#
5.載入系統映像。
