Modifying Device IP in HP IMC

[CCNP87]

Hi Everyone,

We are planning to change the management IP address of the all 150 switches in our campus LAN, so we would like to replace/modify the old IP addresses with the new ones because we want to retain all the previous syslogs, configuraiton files etc....  Rediscovering the devices with new IP addresses will add them as new devices and thats not an option.

I did found 2-3 posts here on HPE Community regarding the same query but the links containing intructions are not valid anymore.

Any help will be greately appreceated.

You can do it by modifying the DB, but it's not a supported procedure. You can do it if you really want, it's not that hard. But you might get a few oddities happening.

You said that it's "not an option" to add as new devices: You have to decide how important is it to you to retain that data vs doing something unsupported. 

What is it that you *really* need from the old data? If it's just syslogs & config files, then you can just take copies of that data - the config files are stored on disk, and syslogs are periodically exported to text.

Just edit IPs in table tbl_dev in schema imc_config in database config_db in SQL

Hello,

Please do not modify the IPs in the database directly as this could cause unforseen issues and is not supported.

Meanwhile there is a way to change the IP addresses of your devices directly in iMC wihout deleting and re-adding them. I'm not sure on which version it was added, but if you are on one of the latest (7.3 E0705+) it should work:

1. Open the file iMC\client\conf\commonCfg.properties in a text editor, and change enableIPModification=false to enableIPModification=true

2. Restart jserver process via DMA. The option to modify the device IP will now be available on Device Details.

Good to know. Should really be enabled by default IMO
