65、76 sup720启动boot问题.doc

修改配置前，boot参数如下：boot system flash sup-bootflash:sup-bootflash的IOS文件为：s72033-psv-mz.122-18.SXD7b.bin系统重启后能正常启动。第一次修改boot参数为：boot system flash disk0:s72033-adventerprisek9_wan-vz.122-33.SXH.binboot system flash sup-bootflash:s72033-psv-mz.122-18.SXD7b.bin保存配置后，查看启动参数：SW03253#show bootBOOT variable = disk0:s72033-adventerprisek9_wan-vz.122-33.SXH.bin,1;sup-bootflash:s72033-psv-mz.122-18.SXD7b.bin,1;CONFIG_FILE variable = BOOTLDR variable = Configuration register is 0x2102重启6509（此时CF卡上有IOS s72033-adventerprisek9_wan-vz.122-33.SXH.bin），系统可以从CF卡上的IOS启动。取走CF卡后再重启6509，提示CF卡初始化失败，进入Rommon模式，在rommon下输入boot bootflash: s72033-psv-mz.122-18.SXD7b.bin，系统正常启动System Bootstrap, Version 7.7(1)Copyright (c) 1994-2003 by cisco Systems, Inc.Cat6k-Sup720/SP processor with 524288 Kbytes of main memoryAutoboot executing command: boot disk0:s72033-adventerprisek9_wan-vz.122-33.SXH.binPCMCIA slot0 device is not initializedopen: read error.requested 0x4 bytes, got 0x0trouble reading device magic numberloadprog: error - on file openboot: cannot load disk0:s72033-adventerprisek9_wan-vz.122-33.SXH.binSystem Bootstrap, Version 7.7(1)Copyright (c) 1994-2003 by cisco Systems, Inc.Cat6k-Sup720/SP processor with 524288 Kbytes of main memoryrommon 1 dir sup-bootflash:bad device name (device not supported) usage: dir usage: dir rommon 2 rommon 3 dir bootflash:File size 45475412 bytes (0x2b5e654)Checksum 0x9bd41dadFile name s72033-psv-mz.122-18.SXD7b.binrommon 4 boot bootflash:s72033-psv-mz.122-18.SXD7b.binSelf decompressing the image : # OK按照NYL论坛上兄弟说的方法：把第二条boot参数冒号后面的文件名去掉，boot system flash disk0:s72033-adventerprisek9_wan-vz.122-33.SXH.binboot system flash sup-bootflash:s72033-psv-mz.122-18.SXD7b.bin修改boot参数为：boot system flash disk0:s72033-adventerprisek9_wan-vz.122-33.SXH.binboot system flash sup-bootflash:SW03253#show bootBOOT variable = disk0:s72033-adventerprisek9_wan-vz.122-33.SXH.bin,1;sup-bootflash:,1CONFIG_FILE variable = BOOTLDR variable = Configuration register is 0x2102保存配置后重启6509（取走外置CF卡），系统还是没按预期的方式正常启动，而是进入rommon模式了，再次boot bootflash: s72033-psv-mz.122-18.SXD7b.bin启动后再修改启动参数（把第二条的sup-bootflash改为bootflash）：修改boot参数为：boot system flash disk0:s72033-adventerprisek9_wan-vz.122-33.SXH.binboot system flash bootflash: s72033-psv-mz.122-18.SXD7b.binSW03253#show bootBOOT variable = disk0:s72033-adventerprisek9_wan-vz.122-33.SXH.bin,1;bootflash:s72033-psv-mz.122-18.SXD7b.bin,1CONFIG_FILE variable = BOOTLDR variable = Configuration register is 0x2102保存配置后重启6509（取走外置CF卡），系统还是没按预期的方式正常启动，而是进入rommon模式了，再次boot bootflash: s72033-psv-mz.122-18.SXD7b.bin启动后再修改启动参数为：修改boot参数为：boot system flash disk0:s72033-adventerprisek9_wan-vz.122-33.SXH.binboot system flash bootflash: SW03253#show bootBOOT variable = disk0:s72033-adventerprisek9_wan-vz.122-33.SXH.bin,1;bootflash:,1CONFIG_FILE variable = BOOTLDR variable = Configuration register is 0x2102保存配置后重启6509（取走外置CF卡），系统还是没按预期的方式正常启动，而是进入rommon模式了，再次boot bootflash: s72033-psv-mz.122-18.SXD7b.bin启动后再修改启动参数(把第二条的system后面的flash去掉，直接写成boot system bootflash：修改boot参数为：boot system flash disk0:s72033-adventerprisek9_wan-vz.122-33.SXH.binboot system bootflash:SW03253(config)#boot system ?WORD TFTP filename or URLflash Boot from flash memoryftp Boot from a server via ftpmop Boot from a Decnet MOP serverrcp Boot from a server via rcptftp Boot from a tftp serverSW03253(config)#boot system bootflash:SW03253#show bootBOOT variable = disk0:s72033-adventerprisek9_wan-vz.122-33.SXH.bin,1;bootflash:,12;CONFIG_FILE variable = BOOTLDR variable = Configuration register is 0x2102保存配置后重启6509（取走外置CF卡），系统以引擎内FLASH中的IOS正常启动（达到预期效果，可以满足客户需求）再修改boot参数为：boot system disk0:boot system bootflash:SW03253#show bootBOOT variable = disk0:,12;bootflash:,12;CONFIG_FILE variable = BOOTLDR variable = Configuration register is 0x2102保存配置后重启（取走外置CF卡），正常启动System Bootstrap, Version 7.7(1)Copyright (c) 1994-2003 by cisco Systems, Inc.Cat6k-Sup720/SP processor with 524288 Kbytes of main memoryAutoboot executing command: boot disk0:PCMCIA slot0 device is not initializedopen: read error.requested 0x4 bytes, got 0x0trouble reading device magic numberboot: cannot open disk0:boot: cannot determine first file name on device disk0:System Bootstrap, Version 7.7(1)Copyright (c) 1994-2003 by cisco Systems, Inc.Cat6k-Sup720/SP processor with 524288 Kbytes of main memoryAutoboot executing command: boot bootflash:Self decompressing the image : # OK再重启（插入CF卡），系统也可以从CF卡的IOS启动System Bootstrap, Version 7.7(1)Copyright (c) 1994-2003 by cisco Systems, Inc.Cat6k-Sup720/SP processor with 524288 Kbytes of main memoryAutoboot executing command: boot disk0:string is disk0:s72033-adventerprisek9_wan-vz.122-33.SXH.binSelf extracting the image.
