Duplicate Listings for Brocade Switches
in Same Fabric
If you discover more than one Brocade switch in the same fabric, the Targets tab displays
duplicate listings for the Brocade switches. Each Brocade switch is listed multiple times with the IP
address of the other switches and its own.
For example, assume you discovered Brocade switches QBrocade2 and QBrocade5 in the same
fabric, the switches are listed twice on the Targets tab. QBrocade2 is listed twice, once with its
own IP address, the other time with the IP address of QBrocade5, as shown below:
192.168.10.22 Switch QBrocade2, QBrocade5 admin
192.168.10.25 Switch QBrocade2, QBrocade5 admin
Element Logs Authentication Errors During Discovery
During discovery, you may see SNMP authentication errors on the element you are trying to
discover. The management server is probing the element with an SNMP request. If the element
does not know the management server, it logs authentication errors.
EMC Device Masking Database Does Not Appear
in Topology (AIX Only)
An EMC device masking database attached to an AIX host does not appear in the Topology tree
under the Application Path - Unmounted node on the Topology tab in System Manager.
If the EMC device masking database is attached to a host running Microsoft Windows or Sun
Solaris, the masking database appears under the Application Path - Unmounted node.
Management Server Does Not Discover Another
Management Server's Database
In some situations the management server may not discover another management server’s
database. Make sure that the Oracle monitoring software (CreateOracleAct.bat for Microsoft
Windows) is installed on the management server to be discovered and that the Oracle instance is
added to the discovery list.
Microsoft Exchange Drive Shown as a Local Drive
Microsoft Exchange Servers have a drive M. The software displays this drive as a local fixed disk,
instead of a Microsoft Exchange Server special drive.
Unable to Discover Microsoft Exchange Servers
If DNS records for your Microsoft Exchange servers are outdated or missing, the discovery of
Microsoft Exchange may fail because Microsoft Exchange is dependant on Active Directory, which
is dependant on DNS. Since Active Directory is dependant on DNS, Active Directory replication
and Active Directory lookups may fail or contain errors if DNS records are not accurate.
Nonexistent Oracle Instance Is Displayed
The software uses the Oracle Transparent Name Substrate (TNS) listener port to detect Oracle
instances on a server. Sometimes an Oracle instance is removed from the server, but not from the
