有台4300需要使用usb升级到JTAC推荐版本,之前我的U盘做成了Srx550的启动盘,格式化将软件版本放进去,插到EX4300上,发现scrt在shell模式下没有输出U盘信息,查询kb发现需要将U盘格式设置为fat32

  1. 重新格式化U盘以后插入,可以看到shell模式下输出:

root@hostname:0% umass1: PNY Hook Attache, rev 2.00/0.00, addr 2

da1 at umass-sim1 bus 1 target 0 lun 0

da1: Removable Direct Access SCSI-4 device 

da1: 40.000MB/s transfers

da1: 7650MB (15667200 512 byte sectors: 255H 63S/T 975C)

  2. 挂载U盘,查看文件,已经可以看到4300的版本(Junos系统是基于freebsd unix,所以查看文件list的命令跟unix一样):

root@hostname:RE:0%  mount_msdosfs /dev/da1s1 /mnt       (这里的对应shell输出)

root@hostname:RE:0%  cd /mnt

root@hostname:0%  ls

.Spotlight-V100

._jinstall-ex-4300-14.1X53-D46.7-domestic-signed.tgz

.fseventsd

 3.将文件复制到var/tmp/里面,(junos文件放置到var/tmp下面)并检查:

root@hostname:0% cp jinstall-ex-4300-14.1X53-D46.7-domestic-signed.tgz /var/tmp

root@hostname:0% cd /var/tmp

root@hostname:0% ls

.snap

ex_autod_config

ex_autod_rollback_cfg

gres-tp

install

jdhcpd.core-tarball.0.tgz

jinstall-ex-4300-14.1X53-D46.7-domestic-signed.tgz

snap

vi.recove

4.安装软件包升级并且重启:

root@hostname> request system software add /var/tmp/jinstall-ex-4300-14.1X53-D46.7-domestic-signed.tgz no-c no-p reboot

这是遇到一个报错:

ERROR: Package signature validation failed.  Aborting install.

查询kb的时候,并没有找到这个error,但是找到另一个kb:U盘升级失败是系统时间的问题。

我设置下系统时间:

root@hostname> show system uptime 

fpc0:

  重新升级:  

root@hostname> request system software add /var/tmp/jinstall-ex-4300-14.1X53-D46.7-domestic-signed.tgz no-c no-p reboot

  系统开始升级重启。


5.设备升级以后检查版本,升级成功:

root@hostname> show version

检查系统时间,自动更新为了2017年。关于上面的这个error,是设备主机和IOS证书认证时时间冲突。
