IMPORTANT: Because of subtle differences between discovery from HP SIM and HP SE, HP
strongly recommends you do either all of your discovery steps in HP SIM or HP SE. See ”Differences
Between HP SE and HP SIM Discovery” on page 18 for more information about the differences
between HP SIM and HP SE discovery.
Discovery from HP SIM Steps
Discovery of switches, storage systems, NAS devices and tape libraries consists of several steps:
1. Discover your switches by using HP Systems Insight Manager. See ”Step 1 - Discover Switches”
on page 34. Refer to the documentation for HP SIM for detailed information about discovery.
2. Discover your storage systems, NAS devices and tape libraries by using HP Systems Insight
Manager. See ”Step 2 - Discover Storage Systems, NAS Devices and Tape Libraries” on
page 61.
3. Obtain details about the elements you previously discovered by using the Run Discovery Data
Collection feature. You must run Get Details to obtain provisioning information. This step takes
some time to complete. Run Get Details when the network is not busy. See ”Step 4 - Discovery
Data Collection or Get Details” on page 97 for more information.
Discovery from HP SE Steps
Discovery for switches, storage systems, tape libraries and NAS devices consists of several steps:
1. Discover your switches. See ”Step 1 - Discover Switches” on page 34.
2. Discover your storage systems, tape libraries, and NAS devices. See ”Step 2 - Discover Storage
Systems, NAS Devices and Tape Libraries” on page 61.
3. (Optional) If you want to view the topology quickly in System Manager, obtain the topology as
described in ”Step 3 (Discovery from HP SE Only) - Build the Topology” on page 92. Keep in
mind this step only gathers the information necessary for displaying the topology.
4. Perform Get Details. Get Details is required to obtained detailed information from the elements
you discovered. You must run Get Details to obtain provisioning information. This step takes
some time to complete. Run Get Details when the network is not busy. See ”Step 4 - Discovery
Data Collection or Get Details” on page 97 for more information.
IMPORTANT: Before performing any provisioning operations that involve a Brocade switch you
must perform Discovery Step 3 for any subset of elements that includes this Brocade switch.
Overall Discovery Tasks
Keep in mind the following:
• Accessing the Discovery pages for discovery from HP SIM or HP SE differs. See ”Accessing the
Discovery Pages for HP SIM and HP SE” on page 19 for details.
• To save time, make sure the user names and passwords are correct. When credentials are not
supplied, the default user names and passwords are tried for the element.
