SGSN备份流程
热度 5 ||
备份(backup): SGSN root权限
1. telnet登陆SGSN,确定节点
=== sysadm@eqm01s13p2 ANCB ~ # gsh get_ne
2. 切换root账户
=== sysadm@eqm01s13p2 ANCB ~ # su –
Password:
3. 启动GAS
root@eqm01s14p2 ANCB ~ # gsa
4. 检查GSS和SGSN是否相连
gsa@primary_FSB(remote)> info
time: 2007_1012_0832 UTC
disc syncronization:
0: cs:Connected st:Primary/Secondary ld:Consistent
1: cs:Connected st:Primary/Secondary ld:Consistent
2: cs:Connected st:Primary/Secondary ld:Consistent
primary_FSB:
front ETH0 : mac 00:01:EC:ED:E8:C2
: ip 10.45.0.15
: bcast 10.45.0.255
: mask 255.255.255.0
GSS server:
ip-address : 10.45.0.251
node path : /gsn/nodes/node186
backup dir : /gsn/nodes/node186/backups
5. 有GSSserver ipaddress,nodepath,backupdir三项显示,说明GSS连通正常,可以备份,并给备份加注标签为example1,系统以一定的格式添加前缀(可自定义,这里是系统时间)作为备份的名称
gsa@primary_FSB(remote)> backup –t example1
6. 大概30分钟备份完成,有如下提示
[OK] The backup /gsn/nodes/sgsncd03/backups/2010_0202_0645_UTC__example1 has all files needed for a restore
7. 检查备份文件
gsa@primary_FSB(remote)> list
Connecting to 10.49.0.1 (10.49.0.1) at port 21...remote system: UNIX Type: L8 Version: SUNOS2009_0410_1443__R8first 2009_0525_1115__predragonboat 2009_0826_1115__August2010_0202_0645__example18. 确认备份文件完整性,如果不完整,应该重新备份
gsa@primary_FSB(remote)> verity 2010_0202_0645 __example1
注:
1.备份过程中不要checkpoint
2.备份适宜在非忙时做
3.如果配置文件多,容量大,磁盘使用率高,将会增加备份的时间.6G的数据大概要花2个小时
4.备份过程中连接中断,备份取消,需要重新开始.所以长时间的备份建议console口登陆进行备份.
GGSN备份
备份(jbackup):GGSN普通账户和root账户权限,1G flash CARD
1. 查看JuniperOS套装版本,确定flashCARD启动所需系统文件的版本,这里用9.0R4.5: (对应文件install-media-9.0R4.5-ggsn-domestic)
ericsson@GGSNCD01-RE0> show version
Hostname: GGSNCD01-RE0
Model: m120
JUNOS Base OS boot [9.0R4.5]
JUNOS Base OS Software Suite [9.0R4.5]
JUNOS Kernel Software Suite [9.0R4.5]
JUNOS Crypto Software Suite [9.0R4.5]
JUNOS Packet Forwarding Engine Support (M/T Common) [9.0R4.5]
JUNOS Packet Forwarding Engine Support (M120) [9.0R4.5]
JUNOS Online Documentation [9.0R4.5]
JUNOS Routing Software Suite [9.0R4.5]
Ericsson Juniper Networks Mobile IP GGSN Software [9.0R4.5]
2. 查看GGSN软件安装包版本,这里是5.1.86.0: (对应文件ggsn-install-5.1.86.0.tgz)
ericsson@GGSNCD01-RE0> show services ggsn status|no-more
Interface: gc-2/1/0
External address: 220.206.149.33
Internal address: 128.0.2.18

PDP services start time: Sun Jan 24 12:39:52 2010 (374136 microsecond)
…….(omitted)
注:也可以直接用命令得到这个版本show snmp mib get ggsnversion.0
3. 进入备用RE1
ericsson@GGSNCD01-RE0> request routing-engine login re1
4. 在配置模式,保存当前配置
ericsson@GGSNCD01-RE1> edit
Entering configuration mode
[edit]
ericsson@GGSNCD01-RE1# save ggsn1stbackup20100202_conf
Wrote 4497 lines of configuration to 'ggsn1stbackup20100202_conf'
[edit]
ericsson@GGSNCD01-RE1# exit
Exiting configuration mode
5. 查看三个文件是否都在当前目录下
ericsson@GGSNCD01-RE1> start shell
% ls
ggsn-install-5.1.86.0.tgz install-media-9.0R4.5-ggsn-domestic
ggsn1stbackup20091218 jbackup.txt
%exit
6. 启动shell,root账户,不要改变登陆路径:
ericsson@GGSNCD01-RE1> start shell
% su#####################注:这里不是su -,保证备份在/home/ericsson/目录下.
Password:
root@ GGSNCD01-RE1%
7. 确定flashCARD已插到备用RE1的USB接口上,开始备份
root@GGSNCD01-RE1% jbackup -d -p install-media-9.0R4.5-ggsn-domestic -j ggsn-install-5.1.86.0 .tgz -c ggsn1stbackup20100202_conf
8. 备份完成,如下提示,记下jbackup[],以便却分备份是否完成.
……(omitted)
jbackup[73492]: Current log file is: jbackup.txt (if it exists)...
jbackup[73492]: Done.
注:有时telnet会话超时中断,提示信息显示不完全,为了确认备份是否完成,需检查文件:
tail jbackup.txt
9. 拔出flashCARD,贴标签,妥善保存
