HP Storage Essentials SRM 6.0 Installation Guide 163
NOTE: For more about data collection, see ”About Discovery Data Collection” on page 153.
When planning discovery groups, consider the following requirements and capabilities:
• By default, HP Storage Essentials is configured with a default discovery group plus four
additional groups.
• Discovery groups affect the amount of memory needed for HP Storage Essentials. Before
configuring discovery groups, check the support matrix for your edition and verify that your
system meets the memory requirements for using discovery groups.
• Do not move elements between discovery groups when Discovery Data Collection is running. If
you do this, an error will occur when Discovery Data Collection tries to locate elements that
were moved.
• An element can be a member of only one discovery group at a time.
• Elements discovered through SMI-S and hosts discovered with CIM extensions from Build 5.1
and later of HP Storage Essentials cannot be added to discovery groups. These elements can,
however, be placed independently into scheduled Discovery Data Collection tasks without
being part of a discovery group. This allows you greater flexibility when gathering discovery
data. For more information, see ”Creating Custom Discovery Lists” on page 162.
• When an element in a discovery group is updated, its dependent elements are also updated.
• Each discovery group communicates over a specific port. The defaults ports are:
Creating Custom Discovery Lists
You can create a discovery list for Discovery Data Collection, which will allow you to select a set of
discovery groups to use the next time Discovery Data Collection runs.
To create a custom discovery list:
1. Select Options > Storage Essentials > Discovery > Run Discovery Data Collection.
2. Click the Specified Discovery Groups link.
3. Select the check box next to each item you want to add to the discovery list.
Elements discovered through SMI-S and hosts discovered with CIM extensions from Build 5.1
and later of the product appear in the list individually. You can add individual elements,
discovery groups, or both to the same discovery list.
4. Click Add Selected Discovery Groups to Discovery List to move them into the Discovery List.
