This article introduces in detail how to modify the IP address of the management port of EMC VNX storage. Note that the VNX storage methods of Unifed and block are different. This is why several friends asked me this question and wrote this blog.
Before modifying the IP address of the management port, make sure that the storage is not in the storage domain. If it belongs to a storage domain, you must remove it from it. Generally in China, it is rare to create a domain for storage alone, so just refer to it. Of course, it is possible for a serious company to put storage in the storage domain.
Here's how to remove storage from the storage domain:
- Determine if the storage is in the domain
- If this storage is the master in the storage domain, you must specify another role of the array to become the master
- If there is only one storage in this storgae domain, delete the domain first before modifying the IP address.
- Check that all hosts have redundant paths, and the failover software is working properly
The following is the specific modification method, there are two different methods:
- Use the setup interface to modify the address, this requires a reboot controller
<SP_IP_address/setup
Commands need to be executed separately on the two controllers
For VNX unified storage, this option is grayed out , so it cannot be modified by this method.
After Apply, it takes 1-2 minutes to restart, and the white hand of SPB lights up.
2. Use the naviseccli command to modify the address, this does not require a reboot controller
This method is only applicable to versions R29 and later, not previous versions
First check the current network configuration.
naviseccli -h <current SPaIP> networkadmin -get //Get the settings corresponding to the -h IP address
C:\IPmitool>naviseccli -h 10.255.199.240 -user sysadmin -password sysadmin -scope 0 networkadmin -get -sp b //Get the address of SPB
The following command is to set the new address
naviseccli -h <current SPaIP> networkadmin -set -address <newSPaIP> -subnetmask <if changing-new IP> -gateway <if changing-newIP>
In actual work, there may be various problems. If you encounter problems, you can add wechat at StorageExpert for further discussion.
