looks correct, it will display native paths. You are using unlicensed PowerPath so you are only protected from SP failover. Also you need to make sure each HBA is zoned to SPA and SPB.

Hi

I am facing same problem and I have already install EMC power path So that may be issue occurred by linux multipathing ??

this is correct, PowerPath will create emcpowerX device, you use this device when you create partitions, pvcreate ..etc. Native devices are always there, just like they are on AIX, HPUX. Each native device represents a path to the LUN, PowerPath knows that and takes advantages of that for loadbalancing, multipathing.

Hi Dynamox,

Issue is that

When we installed EMC Power Path why it showing multi LUN ?it should show only one LUN i.e. EMC powerpath LUN
for example:-

Disk /dev/emcpowera: 10.7 GB, 10737418240 bytes

64 heads, 32 sectors/track, 10240 cylinders

Units = cylinders of 2048 * 512 = 1048576 bytes

     Device Boot      Start         End      Blocks   Id  System

/dev/emcpowera1               1       10240    10485744    5  Extended

but the problem is that it showing multipathing which are as under,

[root@osdd1 scsi]# fdisk -l

Disk /dev/sda: 1195.9 GB, 1195997396992 bytes

255 heads, 63 sectors/track, 145405 cylinders

Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System

/dev/sda1   *           1          13      104391   83  Linux

/dev/sda2              14      145405  1167861240   8e  Linux LVM

Disk /dev/sdb: 10.7 GB, 10737418240 bytes

64 heads, 32 sectors/track, 10240 cylinders

Units = cylinders of 2048 * 512 = 1048576 bytes

   Device Boot      Start         End      Blocks   Id  System

/dev/sdb1               1       10240    10485744    5  Extended

Disk /dev/sdc: 10.7 GB, 10737418240 bytes

64 heads, 32 sectors/track, 10240 cylinders

Units = cylinders of 2048 * 512 = 1048576 bytes

   Device Boot      Start         End      Blocks   Id  System

/dev/sdc1               1       10240    10485744    5  Extended

Disk /dev/emcpowera: 10.7 GB, 10737418240 bytes

what issue are you facing ?

Thanks Dynamox
