故障處理srx5600防火墻的issu升級原理

1、I升級方法，只需要通過一條命令，即可以實現(xiàn) SRX 雙機的無會話中斷升級操作。1.2.通過FTP 方法將升級文件上傳到 Node 0（主）。在 Node 0 上 發(fā) 出 I命令 (userhost request system softwarein-service-upgrade “image_name” reboot)，I進程將檢查config、升級文件和各種兼容性。如果存在問題將提示相關操作或停止繼續(xù)升級。3.4.II將升級文件copy 到 Node 1（備）。在Node 1 上加載新的操作系統(tǒng)文件、并重啟，然后同步RTO（各種實時對象，如ses的操作系統(tǒng)版本是不同的，I表等）。這時主備需

2、要進行大量的檢查工作，如果存在問題將提示相關操作或 停止繼續(xù)升級。5.6.7.II在 Node 0 上加載新的操作系統(tǒng)文件，然后做主備切換。重啟Node 0。最后需要手工將 Node 0 切換為主，恢復為原來的主備關系：a)b)c)d)reqreqreqreqhassis cluster failover redundancy-group 0 node 0 hassis cluster failover redundancy-group 1 node 0 hassis cluster failover reset redundancy-group 0hassis cluster failove

3、r reset redundancy-group 11.只有一臺設備完成升級若I升級失敗，只有一臺設備完成升級，則可在已升級設備上通過如下意外情況處理升級原理：SRX5600的 I升級原理 20120702-v2時間：2012 年 7 月 2 日撰寫：Juniper 工程師概要：命令回退reqhassis cluster in-service-upgrade abortrequest system software rollbackrequest system reboot 2.升級過程中設備掉電如果在發(fā)布I命令后，設備在使用新版本完成啟動前掉電，那么當電力恢復啟動設備后，該設備將仍處于I進程
