2. Open the PolyServe Management Console Connect window, enter the login
credentials for a server in the matrix, and click Configure button on the Connect
window.
3. On the Configure Matrix window, select the Fencing tab and then configure the
appropriate fencing method. See the HP PolyServe Matrix Server installation
guide for more information about this tab.
4. Click Apply (on the bottom of the Configure Matrix window) to install the new
configuration on the server and answer Yes when you are asked if you want to
start the matrix service.
5. Go to the Matrix-Wide Configuration tab and export the new configuration to
the other servers.
6. Start Matrix Server on the remaining servers.
Server cannot be located
If the cluster reports that it cannot locate a server on the SAN but you know that the
server is connected, there may be an FC switch problem.
For example, on a Brocade FC switch, log into the switch and verify that all F-Port
and L-Port IDs specified in switchshow also appear in the local nameserver,
nsshow. If the lists of ports are different, reboot the switch. If the reboot does not
clear the problem, there may be a problem with the switch.
Also consult your FC switch documentation or the FC switch vendor. If the switch
appears to be operating properly, contact HP Technical Support.
Server cannot be fenced
The following command can be used in situations where Matrix Server is unable to
fence a server that is not communicating with the cluster (for example, because the
server has crashed) and you cannot reboot the server. Run the command from a
server that is communicating with the matrix, not from the non-responsive server. If
none of the servers are responsive, try to execute the command from a client using
the Microsoft psexec utility.
mx server markdown <server>
The command informs Matrix Server that the server has been verified to be down
and does not need to be fenced, as it cannot threaten filesystem integrity.
When Matrix Server cannot fence a server, an alert such as the following will be
displayed:
