You perform the initial scan without credentials (the user name and password details that enable you to log in to hosts on the network). This scan produces a list of potential hosts that can be discovered. You must choose the IP range to scan. You should be logged into BMC Atrium Discovery as the discovery user.

    As you enter text, the user interface (UI) divides it into pills, discrete editable units, when you enter a space or a comma. According to the text entered, the pill is formatted to represent one of the previous types or presented as invalid. 

     Click here for more information on using the pill UI.

    Invalid pills are labelled with a question mark. You can also paste a list of IP addresses or ranges into this field. There is no paste option on the context sensitive (right click) menu. 

    Warning

     You cannot paste a comma-separated list of IP address information into the Range field in Firefox. This may crash the browser. You can use a space separated list without any problems.

    • To edit a pill, click the pill body and edit the text.
    • To delete a pill, click the X icon to the right of the pill, or click to edit and delete all of the text.
    • To view the unformatted source text, click the source toggle switch.

    The source view is useful for copying to a text editor or spreadsheet. Click the source toggle switch again to see the formatted pill view. You can also sort the pill view by value or type. Value sorts by ascending numerical value. Type sorts by type, placing invalid pills first. Underneath the entry field is a filter box. Enter text in the filter box to only show matching pills.

    Pills are not currently supported in Opera.

    Level

    Select the level for the discovery run. This is one of: 

    • Sweep Scan: This will do a sweep scan, trying to determine what is at each endpoint in the scan range. It will attempt to login to a device to determine the device type. 
    • Full Discovery: This will retrieve all the default info for hosts, and complete full inference.

    Label

    Enter a label for the discovery run. Where the discovery run is referred to in the UI, it is this label that is shown.

    Company

    Select the company name to assign to the discovery run. This drop-down list is only displayed if multitenancy has been set up. If (No company) is displayed, or a company name that you were expecting is missing, refresh the list by clicking Lookup Companies on the CMDB Sync. See multitenancy for more information about this feature.
