Using the HAFM application 42
Fibre Channel networks use World Wide Names (WWNs) to uniquely identify nodes and ports
within nodes. For many devices, the 64-bit WWNs are fixed, and their assignment follows
conventions established by the IEEE. For other devices, the WWNs can be set or modified by the
user. WWNs are a special concern for SAN Manager because:
• WWNs are used as the primary keys to identify network elements.
• Previous experiences have shown that an ill-formed WWN can be a malfunctioning device.
Proper operation with SAN Manager requires that WWNs be unique within the network and
well-formed (they must be 64 bits in length and the first byte cannot be zero).
Determining user groups
An administrator can determine the groups to which a user belongs:
1. Select SAN > Users.
The Server Users dialog box is displayed (
Figure 26 on page 64).
2. Select a user from the Users table.
3. Click Find.
The groups to which the user belongs are highlighted in the Groups list.
4. Click OK.
Determining the discovery state
NOTE: The Product List panel can be hidden by default. To view the Product List, select View >
Product List or press F9.
You can determine the discovery status of products by looking at the status column in the Product
List. Table 12 lists the operational statuses and their equivalent discovery states.
