HP Virtual Connect Enterprise Manager Software - Manual (Page 100)

After a server profile failover, some connections defined in the server profile are not
functional
VCEM cannot identify if all Fibre Channel and Ethernet connections configured in a server profile can be
physically mapped to the physical ports of a server blade, due to that it is possible to have Ethernet or Fibre
Channel connections in the server profile that cannot be configured in the server blade where it is assigned,
causing those servers to not function.
To correct this issue, perform either of the following:
•
Manually move the affected server profile to a spare server blade that contains all the necessary physical
ports to receive the server profile.
•
Install the necessary mezzanine cards in the server blade to provide the physical port mappings required
by the server profile connections.
Server profiles are not displaying physical port mapping and allocated bandwidth
information
VCEM does not display physical port mapping and allocated bandwidth information for the Ethernet network
connection in a server profile.
To correct this information, perform the following:
1. Go to Virtual Connect Manager user interface.
2. Expand the Server Profiles Assigned Server Profiles left navigation panel and click the desired
server profile.
3. The Physical Port Mapping and Allocated Bandwidth information is presented inside the Ethernet Network
Connection table.
VCEM page displays "Communication with the HP SIM server has been lost"
When VCEM performs a task that requires some time to be completed, HP SIM server might detect that the
task is taking too long and the Communication with the HP SIM server has been lost message
appears.
This behavior is intermittent, but can occur in the following situations:
•
When navigating through VCEM pages and requesting multiple operations at the same time
•
When VC Domains that are being managed by VCEM are having a communication outage
To solve this issue, press Refresh to reload the VCEM page, and then perform the desired operation again.
To prevent the issue from happening again, perform either of the following:
•
Verify that the Central Management Server has the minimum hardware requirements to run VCEM.
•
Verify that all VC Domains are correctly communicating with the Central Management Server.
VC Domain not discovered by HP SIM
If SNMP protocol is not correctly configured, then HP SIM cannot correctly discover the unconfigured VC
Domains, and then you might not be able to see such VC Domains or the VC Domains list.
To correct this issue, perform one of the following:
•
Access the HP SIM menu, select Options
→Discovery→Configure Global Credentials, and verify
the first SNMP read community string is public.
•
Access the HP SIM menu, Select Options
→Discovery→Configure Global Protocol Settings, and
verify that the Enable SNMP option is selected.
•
Run HP SIM discovery on the Onboard Administrator IP address related to the VC Domain by accessing
the HP SIM menu and selecting Options
→Identify System or Options→Discovery.
