How to manage CI Alias in ServiceNow ?

[Sanjeev Kumar1]

Hi All,

I review alias tables in Service-now we have following tables (see image) for alias.

If you check cmdb_alias table it has following fields.

1. CI
2. IP address
3. Type

we want to manage CI Alias in ServiceNow but we also need to insert Alias Name in table.

but cmdb_alias does not have alias Name field.

Can we add Alias Name filed in this table OR there is any other way to manage CI Alias in ServiceNow.

Please suggest on same. ?

The CMDB Alias table (cmdb_alias) is used for DNS Aliases, like when you have one server with 8 different aliases and each alias is assigned a different IP address (for example 10.243.4.40 - 48/255.255.255.0). It sounds like you may be asking for a different use case. What are you trying to do?

The Alias table (cmdb_ci_alias) is used for a process called "Field Normalization". See the product documentation page: What field normalization does

I have the same need - to be able to add DNS Aliases for a CI/IP to the CMDB.   I also have looked at all the 'alias' tables and not finding any logic on how they are used.   My need isn't strictly aliases for a CI with several different IPs.   I also have several aliases pointing to one CI/IP.

I want to be able to have a related list on the server CI lthat ists the "DNS Aliases" for the Server/IP.

I don't want to have to modify the OOB tables if I don't need to,   but I need help understanding the tables/processes used for managing DNS aliases.

Hi Candy,

For your requirement you can use OOB "cmdb_alias" table.

It's help full for you.
