6509 SUP720 boot 参数配置总结

6509 SUP720启动参数配置

需求：6509启动时先找外置CF卡上的IOS并从外置CF卡上的IOS启动，如果外置CF卡取出后，6509重启时找不到CF卡，系统从引擎内flash中的IOS启动

配置过程：

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.bin

boot system flash sup-bootflash:s72033-psv-mz.122-18.SXD7b.bin

保存配置后，查看启动参数：

SW03253#show boot

BOOT 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

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.bin

boot 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.bin

boot system flash sup-bootflash:

SW03253#show boot

BOOT variable = disk0:s72033-adventerprisek9_wan-vz.122-33.SXH.bin,1;sup-bootflash:,1

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）：

boot system flash disk0:s72033-adventerprisek9_wan-vz.122-33.SXH.bin

boot system flash bootflash: s72033-psv-mz.122-18.SXD7b.bin

SW03253#show boot

BOOT variable = disk0:s72033-adventerprisek9_wan-vz.122-33.SXH.bin,1;bootflash:s72033-psv-mz.122-18.SXD7b.bin,1

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：

boot system flash disk0:s72033-adventerprisek9_wan-vz.122-33.SXH.bin

boot system flash bootflash:

SW03253#show boot

BOOT variable = disk0:s72033-adventerprisek9_wan-vz.122-33.SXH.bin,1;bootflash:,1

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)：
boot system flash disk0:s72033-adventerprisek9_wan-vz.122-33.SXH.bin
boot system bootflash:

[SW03253(config)#boot system ?
  WORD   TFTP filename or URL
  flash  Boot from flash memory
  ftp    Boot from a server via ftp
  mop    Boot from a Decnet MOP server
  rcp    Boot from a server via rcp
  tftp   Boot from a tftp server
SW03253(config)#boot system bootflash: ]

SW03253#show boot
BOOT 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 boot
BOOT 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

总结
经过N次重启6509，终于搞定了boot参数的配置。但是还有两个问题不明白：
1.配置boot 参数时时，什么情况下使用boot system flash disk0： (boootflash/sup-bootflash)，什么情况下使用boot system  disk0:  (boootflash/sup-bootflash)？
2.BOOT variable = disk0:,12;bootflash:,12;（没有flash关键词时是12），BOOT variable = disk0:s72033-adventerprisek9_wan-vz.122-33.SXH.bin,1;bootflash:,1（有flash关键词时是1），12、1分别代表什么？还有其它值吗？

我顶一下，我没您这么复杂，
反正两块引擎啊，我在一块引擎上把新的IOS灌进去老IOS删除，然后改下boot参数，然后重启，如果能顺利boot起来的话，那么就把另一块板子的IOS也升级了，如果不行的话，copy一下主备板子的IOS也就可以灾备了
