You may want to try this, although I have never used it myself
(Note: type the command directly, do not Copy/Paste from this Forum string)
omnirpt -report cell_info -tab -log [destination file path]
You did not specify whether your Cell Manager is uNIX or Windows, but, assuming it is Windows, your [destination file path] (Do not include the [ ] marks) might be something like D:\temp\list_of_hosts.txt
As you can see this is output as a 'text' file, but wait, there's more. The '-tab' argument means that the output fields are seperated by 'tab' characters, and, therefore, the output can be put into a Excel spread sheet, where you can exclude any columns that are not useful. Unfortunately, the 'omnirpt' does not get any more granular than this
The command can be put into a 'batch' file or a UNIX script in the 'Program Data -> Omniback -> bin folder, and can be run as a pre-exec or post-exec script
