故障现象:

VNX Unified系列在用VIA做File部分初始化的时候,只能做一次,如果配置一半的时候失败或者关闭了VIA的窗口,VIA就无法再次扫描到该存储。


解决方案:

1、使用Putty等软件通过串口线登录CS0,注意这里的串口线必须是随机自带的串口线,因为CS的接口特别窄,其他串口线会无法插入。串口速率19200

a)、串口登录CS0  用户名:root   密码:nasadmin

注意:如果存储是双CS配置的话,可以先把CS1给关闭,拔掉线缆,然后配置完成VIA之后,再把CS1添加上,或者按照下面的方法来设置双CS配置。

b)、从CS前面板的标签中记录下CS0和CS1的 eth3的MAC地址,或是运行以下命令来查看MAC地址并记录eth3的IP:

# /sbin/ifconfig eth3

2、运行命令:

# /nasmcd/sbin/clariion_mgmt -info

如果返回:

Error 12: Not configured

说明proxy ARP没有配置,可以直接跳到步骤3。如果Proxy ARP已经配置,运行以下命令来将SP的ip恢复到出厂设置:

# /nasmcd/sbin/clariion_mgmt -stop

返回信息:

Checking if running as root...yes

Checking if model is supported...yes

Checking for integrated system...yes

Checking if interface eth3 is configured...yes

Checking if SP (10.241.168.206) is up...yes

Checking if SP (10.241.168.207) is up...yes

Step 1/12 [28185788417]: Changing SPA IP address.

Changing SPA IP from 10.241.168.206 to 128.221.252.200 (subnetmask 255.255.255.0, gateway 128.221.252.104)

Step 2/12 [28185788421]: Waiting for SPA to restart.

Waiting for SPA to go down.....done (19 secs)

Step 3/12 [28185788425]: Waiting for ping response from SPA.

Waiting for 128.221.252.200 to respond...done (2 secs)

Step 4/12 [28185788427]: Waiting for CLARiiON software to start on SPA.

Waiting for CLARiiON software to start on SPA...done (61 secs)

Waiting until SPB sees 128.221.252.200 in the domain...done (4 secs)

Step 5/12 [28185788429]: Updating NAS database with SPA IP address.

Adding rules to allow outbound traffic from SPB

Updating SYMAPI database with new CLARiiON IP addresses...done (33 secs)

Step 6/12 [28185788433]: Removing Proxy ARP for SPA on Control Station

Removing host specific route for SPA

Removing rules that allow outbound traffic from SPA

Removing ARP entry for SPA

Updating /etc/hosts entry for SPA

Step 7/12 [28185788418]: Changing SPB IP address.

Changing SPB IP from 10.241.168.207 to 128.221.253.201 (subnetmask 255.255.255.0, gateway 128.221.253.104)

Step 8/12 [28185788422]: Waiting for SPB to restart.

Waiting for SPB to go down.....done (18 secs)

Step 9/12 [28185788426]: Waiting for ping response from SPB.

Waiting for 128.221.253.201 to respond.....done (14 secs)

Step 10/12 [28185788428]: Waiting for CLARiiON software to start on SPB.

Waiting for CLARiiON software to start on SPB...done (37 secs)

Waiting until SPA sees 128.221.253.201 in the domain...done (2 secs)

Step 11/12 [28185788430]: Updating NAS database with SPB IP address.

Updating SYMAPI database with new CLARiiON IP addresses...done (20 secs)

Step 12/12 [28185788434]: Removing Proxy ARP for SPB on Control Station

Removing host specific route for SPB

Removing rules that allow outbound traffic from SPB

Removing ARP entry for SPB

Updating /etc/hosts entry for SPB

FINISH: Operation took a total time of 4 minutes 35 seconds to complete.

3、运行以下命令来检查 /etc/rc3.d下是否存在” S95cable_check”文件:

# cd /etc/rc3.d

# ls -la S95cable_check

4、如果该文件存在,可直接跳至下一步。如果该文件不存在并且之前也没有保留备份的话,那么你需要从对应版本的NAS光盘中来提取这个文件,并通过WinSCP等软件将文件传输到存储上。

文件在光盘的路径如下:

emcnas7.1.47.5_DVD.iso\EMC\nas\

附件中有7.1.47.5版本需要的文件,可直接提取

5、使用网线连接eth3,并使用WinSCP登录eth3的ip,将该文件复制到 /etc/rc3.d/目录下

6、更改文件权限

# chmod 755 S95cable_check

7、 删除临时文件

# rm -rf  /tmp/.factory*

# fm -rf /tmp/factory*

8、用vi命令修改hosts文件,删除CS0的主机名那一条

# vi  /etc/hosts

删除跟CS0有关的主机名和ip的字段,如果是双CS配置,在CS1上也要删除

9、 如果是单CS配置,请直接跳至第10步,如果是双CS配置,请操作以下步骤:

a) 从CS0上SSH登录CS1

# ssh 128.221.252.101

b) 停止CS1上的NAS服务

# /sbin/service  nas stop

c) 退出CS1的SSH,停止CS0上的NAS服务

#/sbin/service  nas stop

d) 用串口登录CS1的root帐号并执行以下操作:

a、拷贝S95cable_check文件到  /etc/rc3.d(该操作需要用WinSCP登录CS1的eth3)

b、删除 /etc/hosts 文件中CS1的主机名和IP地址

c、删除  /etc/sysconfig/network-scripts/ifcfg-eth3配置文件

d、重启CS1,直至出现如下信息:

Waiting for VNX Installation Assistant to continue....

10、 删除CS0上的 /etc/sysconfig/network-scripts/ifcfg-eth3 配置文件

11、 重启CS0,直至CS0出现如下信息:

Waiting for VNX Installation Assistant to continue....

12、启动VIA对VNX Unified进行初始化操作
