如何更改VNX Storage Processsor和Control Station管理地址?
解决方案:
准备工作 a) 列出VNX Storage Processsor和Control Station的新的IP地址清单。 b) 用串口线连接CS0,并通过putty登陆。注:从Control Station的背面看,串口位于最右边。 [/url] c) 登陆Putty,配置参数如下: - bits per second: 19200
- data bits: 8
- parity: None
- stop bit: 1
- flow control: None
- Telnet terminal ID: ANSI
d) 作为用户nasadmin登陆,进入根目录$ su root 情景一:新的IP地址和原地址在不同网段 1. 用下列命令暂停SP的Proxy ARP。这时原IP地址将不再回应任何ARP请求,即原地址失效。恢复到出厂的管理地址128.221.252.200和128.221.252.201。 # /nas/sbin/clariion_mgmt -stop # ping 128.221.252.200 [SPA] # ping 128.221.253.201 [SPB] 2. 更改CS0的IP地址,并验证: a) 更改CS0的IP地址,并验证: # nas_cs -set -ip4address 10.240.210.110 -ip4netmask 255.255.255.0 -ip4gateway 10.240.210.1 OK # nas_cel -list id name owner mount_dev channel net_path CMU 0 c250 0 10.240.210.110 FNM001046001132007 # grep <cs0_name> /etc/hosts 10.240.210.110 c250.emc.com c250 b) 等待5-15分钟,CS0的新IP地址将被更新到管理域domain中。 # /nas/sbin/navicli -h 128.221.252.200 domain -list # /nas/sbin/navicli -h 128.221.253.201 domain -list 注:在两个SP上最终的结果会显示CS0的新IP地址。 c) 如果有必要,插拔管理端口的端口到另一台交换机。 d) 如果只有单个Control Station,直接进入步骤5。如果有两个Control Station,继续下一步。 3. 从CS0切换至CS1,修改CS1的IP地址并更新至管理域domain。 a) 从CS0切换至CS1: # /nas/sbin/cs_standby -failover The system will reboot, do you wish to continue? [yes or no]: yes Failing over from Primary Control Station... b) 用串口线连接CS1,并通过putty登陆。确认CS1是当前的Primary control station。 # /nas/sbin/getreason 11 - slot_0 secondary control station 10 - slot_1 primary control station -->这里显示"Primary" 5 - slot_2 contacted 5 - slot_3 contacted # ps -ef |grep boxm # ps -ef |grep nas_m c) 更改CS1的IP地址,并等待5-15分钟,确认CS0的新IP地址将被更新到管理域domain中。 # nas_cs -set -ip4address 10.240.210.111 -ip4netmask 255.255.255.0 -ip4gateway 10.240.210.1 OK # nas_cel -list # /nas/sbin/navicli -h 128.221.252.200 domain -list # /nas/sbin/navicli -h 128.221.253.201 domain -list # grep <cs1_name> /etc/hosts 10.240.210.111 cs1_250.localdomain cs1_250 d) 如果有必要,插拔管理端口的端口到另一台交换机。 4. 从CS1切换回CS0,等待CS0的IP地址再次更新至Domain。 a) 从CS1切换回CS0。 # /nas/sbin/cs_standby -failover The system will reboot, do you wish to continue? [yes or no]: yes Failing over from Primary Control Station... b) 用串口线连接CS0,并通过putty登陆。确认CS0当前是primary control station。 # ps -ef |grep boxm # ps -ef |grep nas_m # /nas/sbin/getreason 10 - slot_0 primary control station 11 - slot_1 secondary control station c) 等待几分钟再次更新CS0 IP到domain中。 # /nas/sbin/navicli -h 128.221.252.200 domain -list # /nas/sbin/navicli -h 128.221.253.201 domain –list 5. 在SPA和SPB上启用Proxy ARP、配置新的IP地址并确认新地址生效,整个过程大概需要15分钟。 # /nas/sbin/clariion_mgmt -start -spa_ip 10.240.210.112 -spb_ip 10.240.210.113 # /nas/sbin/getreason # nas_storage -c -a # ping 10.240.210.112 # ping 10.240.210.113 # /nas/sbin/navicli -h 10.240.210.112 domain -list # /nas/sbin/navicli -h 10.240.210.113 domain –list 6. 登陆Unisphere,确认IP地址是否修改成功。 [url=http://think.lenovo.com.cn/htmls/knowledge/detail_20160713175152622.html]http://<SPA_IP_address> http://<SPB_IP_address> http://<CS0_IP_address> 情景二:新的IP地址和原地址在同一网段 1. 用下列命令更改两个SP的IP地址,确认新地址生效。 # /nas/sbin/clariion_mgmt -modify -spa_ip 10.240.200.52 -spb_ip 10.240.200.53 # ping 10.240.200.52 # ping 10.240.200.53 # tail /etc/hosts 10.240.200.52 A_FNM00104600113 SPA # CLARiiON SP 10.240.200.53 B_FNM00104600113 SPB # CLARiiON SP # nas_storage -c -a Discovering storage on c250 (may take several minutes) done # /nas/sbin/navicli -h 10.240.200.52 domain -list # /nas/sbin/navicli -h 10.240.200.53 domain –list 2. 更改CS0的IP地址,并确认新地址更新至Domain中。 # nas_cs -set -ip4address 10.240.200.50 -ip4netmask 255.255.255.0 -ip4gateway 10.240.200.1 OK # nas_cel -list id name owner mount_dev channel net_path CMU 0 c250 0 10.240.200.50 FNM001046001132007 # /nas/sbin/navicli -h 10.240.200.52 domain -list # /nas/sbin/navicli -h 10.240.200.53 domain -list # grep <cs0_name> /etc/hosts 10.240.200.50 c250.emc.com c250 3. 对于有两个Control Station的VNX设备,需要从CS0切换至CS1,更改CS1的IP地址,等待CS1新地址更新至Domain。 a) 从CS0切换至CS1 # /nas/sbin/cs_standby -failover b) 登陆CS1,并确认CS1是当前的primary control station。 # /nas/sbin/getreason 11 - slot_0 secondary control station 10 - slot_1 primary control station 5 - slot_2 contacted 5 - slot_3 contacted c) 更改CS1的IP地址,并确认新地址更新到Domain中。 # nas_cs -set -ip4address 10.240.200.51 -ip4netmask 255.255.255.0 -ip4gateway 10.240.200.1 OK # nas_cel -list # grep <cs1_name> /etc/hosts 10.240.200.51 cs1_250.localdomain cs1_250 # /nas/sbin/navicli -h 10.240.200.52 domain -list # /nas/sbin/navicli -h 10.240.200.53 domain –list 4. 从CS1切换回CS0,等待CS0的IP地址再次更新至Domain。 a) 从CS1切换回CS0 # /nas/sbin/cs_standby -failover b) 登陆CS0,并确认CS0是当前的primary control # /nas/sbin/getreason 11 - slot_0 primary control station 10 - slot_1 secondary control station 5 - slot_2 contacted 5 - slot_3 contacted c) 确认CS0地址更新至Domain # /nas/sbin/navicli -h 10.240.200.52 domain -list # /nas/sbin/navicli -h 10.240.200.53 domain -list 5. 登陆Unisphere,确认IP地址是否修改成功。 http://<SPA_IP_address> http://<SPB_IP_address> http://<CS0_IP_address> |
