Hi,

we have provide only one lun(10GB) both the host servers(Linux 5.6, Kernel 2.6)   than after we install EMC power path on the both the servers, When i check  fdsik -l command it giving following output

[root@osdd1 scsi]# fdisk -l

Disk /dev/sda: 1195.9 GB, 1195997396992 bytes

Below is our Host to SAN Configuartion

We have server(IBM X3650M3) with Single HBA(Emulex) card having 2 ports, Two Switches(cisco MDS 9124) and EMC Clariion cx4-960 (in this we are using SP-A and SP-B deafult Ports ).

When we installed EMC Power Path why it showing multipathing? I need clarifcation on the same from ur side saying that is it ok to show the information like /dev/sdb and /dev/sdc. in my view it should show only one path i.e. /dev/emcpowera1 why it showing /dev/sdb and /dev/sdc paths

for more information on powerpath
