Storage Essentials 5.1 Installation Guide 135
When you are asked if you want to remove the access points and its associated elements, keep
in mind these elements will not be deleted if they are accessible from an access point not listed
in the Delete Access Points window. For example, assume you selected access point
192.168.10.25 to be deleted. You are then told that switch1 will be deleted along with the
access point. Let's assume switch1 is accessible from another access point, 192.168.10.29.
When you remove access point 192.168.10.25, switch1 will still be accessible because it can
be accessed from another access point that has not been removed.
4. Click OK if you want to remove the access points listed in the Delete Access Points window.
The access points are removed. If the elements listed have no other access points, they are no
longer accessible from the management server.
Step 4 - Discovery Data Collection or Get Details
This section describes the following:
• ”Get Details or Discovery Data Collection” on page 136
• ”Stopping the Gathering of Details” on page 137
• ”Excluding EMC Symmetrix Storage Systems from Force Device Manager Refresh” on page 138
• ”Excluding HDS Storage Systems from Force Device Manager Refresh” on page 139
Get Details or Discovery Data Collection
Get Details or Discovery Data Collection is required to obtained detailed information from
discovered elements. Get Details/Discovery Data Collection must be performed before you can do
provisioning and/or obtain provisioning information, such as data about zone sets and LUN
numbers.
Keep in mind the following:
• Get Details/Discovery Data Collection takes some time. You might want to perform this process
when the network and the managed elements are not busy. (Discovery from HP SE only)To
obtain a picture of device connectivity quickly, click the Get Topology button on the Topology
tab.
• During Get Details/Discovery Data Collection the topology in System Manager is recalculated.
While the topology is being recalculated, the loading of the user interface in Storage Essentials
may be slow.
• If you have problems obtaining information from Connectrix and McDATA switches during Get
Details/Discovery Data Collection, see the topic, ”Step 2 - Discover Storage Systems, NAS
Devices and Tape Libraries” on page 99.
• You can use discovery groups to break up getting the topology (Discovery from HP SE only) or
Get Details/Discovery Data Collection. For example, instead of Get Details/Discovery Data
Collection for all of the elements, you could specify that the management server Get
Details/Discovery Data Collection for only the elements in Discovery Group 1, thus, saving you
time. You add an element to a discovery group by modifying the properties used to discover the
element. See ”Moving Elements to Another Discovery Group” on page 144 for information on
how to move one or more multiple elements to a discovery group. You can also move an element
to another discovery group when you modify its discovery properties. See ”Modifying the
Properties of a Discovered Address” on page 132.
