multipath -ll command doesn't give any output
Hi all,
I am new to configure storage in multipath. I have configured multipath in a newly installed oracle Linux 6.0 following Linux documentation; however, when I tried to list the multipath using the commands, it doesn’t show any output. I have stop and restart services, reboot the server to no fix. I have also check the LUNs that I can see the storage array's FC target ports from the server as well as the storage admin confirm that they are properly connected. Blew is the output when I used the commands. Please help and let me know if you need more info...
root@server1 ~]# multipath -ll
[root@server1 ~]# <-- no output
[root@server1 ~]# ps -ef |grep multipath
root 2563 2437 0 16:10 pts/0 00:00:00 grep multipath

[root@server1 ~]# multipath -d
