Direct boot eXR ISO by iPXE

The article should applies to all eXR platform, include ASR9k, NCS5500, NCS6k. The output information maybe different by diff platform, but the iPXE method should same. Btw in eXR, if you want to recovery password, will require iPXE.

How to upgrade eXR by one cmd “install replaced” | NCS5500

Awesome upgrade cmd for eXR, that will help customer simplify upgrade procedure and do upgrade automation! Feature release from 652. Just tested and summarized.

I summarized normal upgrade eXR version by install add/prepare/active at former: Upgrade/Install Packages in eXR. For the article, will summary how to upgrade by install replaced.

“Install replaced” is a new cmd that help customer upgrade only by one cmd, don’t need to add/prepare/active steps, that only support by GISO. What is GISO? That is an image bundle, customer can flexibly customize the image, e.g only bundle: ISIS rpm + mini iso + k9 rpm + configuration to one GISO, more GISO information, please check CCO Doc: Flexible Packaging Configuration Guide for Cisco NCS 5500 Series Routers

PS: “Install replaced” that will not affect running configuration, and auto removes inactive rpm, and commit.

Upgrade/Install Packages in eXR

Seperate RPM Pacakage

Check now version

Due to now version include multi packages, so you must include those packages when you upgrade:

Upgrade XR for ASR9k/CRS/GSR by TURBOBOOT

[对于XR的升级,就我现在所知的有以下几种,如果还有其他的方法,到时再更新]
1. Golden Disk升级
类似于Ghost系统,在现有XR设备(version A)上直接把整个系统文件backup到disk卡中,然后把这个disk卡放到要升级的机箱上(version B),指定boot位置并重启,就可以直接用新系统了(version A)。省了安装系统的时间。但由于需要指定boot路径,另外还需要copy MBI文件到bootflash,所以操作起来感觉不是非常方便。

2013-9-18 更新:
在2010-9-24 更新中的第3和第4小点中,已经总结了一些GoldenDisk的内容。这里再提一下,如果从老版本升级到新版本,如3.6.3到4.0.4,又需要用FAT32,那么一定要把MBI拷贝到bootflash,否则无法识别FAT32;另外还要记住升级前要升级rommona/b的版本,原因下面有解释。

在3.6.3上升级rommon的步骤如下:
1. 从官网下载较新的rommon tar文件
2. 拷贝到disk0中
3. 执行upgrade rommon a/b all disk0

如果客户安装了很多SMU,又不知道正确的MBI路径,那么可以在老系统中把默认的MBI路径拷贝到bootflash中,然后启动,设备会自动boot这个MBI,如果MBI不正确,它会自动把正确的MBI文件copy到bootflash中,然后重启并用新MBI启动,如下所示:

Install (Node Preparation): Booting with committed software
Install (Node Preparation): Checking free space on /bootflash/
Install (Node Preparation): Copying MBI from /disk0/hfr-os-mbi-4.0.4.CSCuc17728-1.0.0/mbihfr-rp.vm
Install (Node Preparation): Copying MBI to /bootflash/disk0/hfr-os-mbi-4.0.4.CSCuc17728-1.0.0/mbihfr-rp.vm
insthelper: This node was booted with an incorrect MBI (/bootflash/disk0/hfr-os-mbi-4.0.4/mbihfr-rp.vm), rebooting self with correct boot image (/bootflash/disk0/hfr-os-mbi-4.0.4.CSCuc17728-1.0.0/mbihfr-rp.vm).

2. Turboboot 升级
完全重新安装,在Rommon模式中download mini PIE文件,感觉像之前IOS环境下的启动新版本那样。只不过XR是要安装,而IOS直接调用。
3. 直接在原有系统上升级
打个比方说,在windows xp的基础上直接升级到windows 7,这样即使windows 7装完了,在新系统中仍然有老系统的东西。所以一般不推荐用这种方法。对于disk存储介质,最好只有1种操作系统,这样稳定些。

2013-11-29 更新:
在现有系统升级又分两种方式:
一种是直接安装PIE文件,如果你的版本是A,要升级B,那么直接active B的PIE即可,但要注意,A和B的PIE要保持一致才能安装,否则会有兼容,如下所示(注:现有系统升级后,配置是保留的):

另一种方式是直接安装下载后的TAR文件,或者自己做的一个TAR文件,以后有机会抓着部分信息,在更新上去。

关于rommon的一些问题
CRS一共有两个rommon,rommon A和rommon B。平时启动都是rommon B,rommon A只做一些工厂检测用。[如果rommon A的版本不低于1.52(这是CRS的需求,9k的另需要确认),就不用升级rommon A。因为每次启动都会由rommon A 去disk卡中check一些信息,感觉像是rommon在加载一些命令集(monlib ?),使得如果rommonB不能启动,或是坏了,可以直接从rommon A启动进行检测。如果版本低于1.52,rommon A就会不识别fat32的disk,所以就停在那里无法继续进行加载rommon B,如果是fat16,就没有任何问题]
