Hi all,

I am in the process of creating a DML (or DSL if you're using ITIL V2) and I am thinking about the CI identifiers to use.

At present, our computer hardware is uniquly identified using the naming convention AA1234, AA1235, AA1236 etc.

For the DML CIs such as physical installation CDs, I am thinking of attaching labels to them with a similar naming convention, eg DM0001, DM0002, DM0003 etc.

For the "logical" CIs stored on a server, eg Printer Drivers, I am unsure how to name the CI.
It will be difficult to use a similar identifier to the CDs for example, as you can't attach a label to a logical CI!

Perhaps the name of the driver could be used as the CI identifier, eg HPLJ4100XP.

Any thoughts / hints / tips etc?

Many thanks

You can use more than one identifier for a specific CI

1 the record ID - this is created by the database - usually people let the system do this. This ensures unique IDs
2 - the name of the CI - this should be a contextual unique
server01, router01, server02 etc

you can make that as simple or as complex as your required

3 - DNS record ID - this may not match #2
4 - IP address

Then you have attributes such as product name, product type, vendor, manufacturer etc like your HP driver for printers bought at tesco's

the use / choice of ID should follow DB normalization standards and the requirements for the DB
