FCIP/GigE Performance Graphs
If there are no FCIP/GigE performance graphs shown for a switch, verify that the server IP address
is properly registered in the SNMP trap registration table. To verify the IP address, enter the CLI
command snmpconfig --show snmpv3 and verify that the SNMPv3 credentials exactly match
the SNMPv3 user that the DCFM server is registered with for traps.
Management of M-series/McDATA switches requires a B-series switch
DCFM management accesses the switches through one B-series switch in each fabric. To use DCFM
to manage M-series or McDATA switches, at least one B-series switch must be connected to the fabric.
At this time, only the HP StorageWorks 4/256 SAN Director (Brocade 48000) and HP StorageWorks
DC SAN Backbone Director (Brocade DCX) are supported for interoperability with M-series switches.
For the latest support information, see the HP StorageWorks Fabric interoperability: Merging fabrics
based on M-series and B-series Fibre Channel switches application note at
Pages.internal/spock2Html.aspx?htmlFile=an_fabric_interoperability.internal.html.
Removing switches
If you plan to segment and remove more than two switches from a fabric and you have historical
performance collection enabled, HP recommends that you accept changes after each switch
segmentation from the client.
DCFM clients
To free up server resources and as best practice, HP recommends that you shut down clients that are
not actively used. In some scenarios, if duplicate entries are displayed in the Product List, restart the
client.
Secure FOS fabrics cannot be discovered from DCFM
DCFM does not support Secure FOS (SFOS). If you attempt to discover an SFOS fabric, DCFM displays
the message Discovery Failed. To recover, you must remove the SFOS settings and set normal
fabric settings.
Performance Data Aging tab has been removed from Server Management
Console
You cannot configure the Performance Data Aging settings in DCFM 10.1.4. The tab has been removed
from Server Management Console (SMC). The default configuration settings are as follows:
•
288 samples in a 5-minute period (1 day)
•
144 samples in a 30-minute period (3 days)
•
84 samples in a 2-hour period (1 week)
•
90 samples in a 1-day period (3 months)
•
606 total samples
When migrating from an earlier release to DCFM 10.1.4, all historical data will be truncated with
respect to the default samples, and the aging configuration will not be migrated.
SNMPv3 credentials for FOS switches when migrating from EFCM
When migrating from EFCM to DCFM, the SNMPv3 credentials for the FOS switches are incorrectly
assigned to the user ID (Discovery Dialog > IP Address tab > User ID). You must clear the user ID
manually before you can discover and manage the FOS switches.
