3. When you are asked if you want to remove the selected elements from quarantine, click OK.
The next time you perform Get Details/Discovery Data Collection for the element, the
management server gathers data from the element.
Updating the Database with Element Changes
After you have initially discovered the elements, information about them might change. To update
database with these changes, perform the steps described in this section.
Keep in mind the following:
• If you change the password of a host after you discover it, you must change the password for the
host in the discovery list. Then, you must stop and restart the CIM Extension running on that host
before you run a discovery.
• If you are adding, removing or replacing McDATA or Connectrix switches, you must perform
different steps. See the topics, ”Adding McDATA and EMC Connectrix Switches” on page 103,
”(Discovery from HP SE Only)Removing McDATA and EMC Connectrix Switches” on page 104,
and ”(Discovery from HP SE Only)Swapping McDATA and EMC Connectrix Switches” on
page 104.
• (Discovery from HP SE only)Get Details takes some time. You might want to perform this process
when the network and the managed elements are not busy. To obtain a picture of device
connectivity quickly, click the Get Topology button on the Topology tab.
Discovery from HP SIM
1. Click Options > Storage Essentials > Discovery > Run Discovery Data Collection.
2. Select Include infrastructure details, which gathers information about SAN details. Include
backup details is used for gathering information for Backup Manager. You do not need to
select Include backup details unless you have already discovered hosts running backup
applications and installed CIM Extensions on those hosts. See ”Step 1 - Discovering Your Hosts
and Master Backup Servers” on page 113 for more information about discovering master
backup servers. The Include backup details option gathers the latest information about your
backup applications.
3. The management server obtains most of its information from device managers for storage
systems with external databases, such as HP, HDS, and EMC storage systems. Select Force
Device Manager Refresh if you want the management server to tell the device managers for
your storage systems to obtain the latest information. If you do not select Force Device
Manager Refresh, the management server gathers information from the external databases
with the assumption the information in the external database is up to date. See the following
topics for more information: ”Excluding EMC Symmetrix Storage Systems from Discovery” on
page 66 and ”Excluding EMC Symmetrix Storage Systems from Force Device Manager Refresh”
on page 100.
4. Click the Get Details button.
5. View the status of the gathering of element details by looking in the View Logs page. See the
topic, ”Viewing Log Messages” on page 59 for more information about the messages viewed in
this tab.
