devices not found with setup of Powerpath v5.3 and HP's EVA4400

hello,

Powerpath is am unable to see the LUNs on a EVA4400 disk array.   Here is what I do:

# powermt display dev=all
Device(s) not found.

When I run lvmdiskscan, I can see the LUNs, but powerpath doesn't

# lvmdiskscan
  /dev/sdq  [       20.00 GB]
  /dev/sda1 [      101.94 MB]
  /dev/sda2 [      136.02 GB] LVM physical volume
  /dev/sdb  [       50.00 GB]
  /dev/sdr  [       20.00 GB]
  /dev/sdc  [       50.00 GB]
  /dev/sds  [       15.00 GB]
  /dev/sdd  [       50.00 GB]
  /dev/sdt  [       40.00 GB]
  /dev/sde  [       50.00 GB]
  /dev/sdu  [       40.00 GB]
  /dev/sdf  [       20.00 GB]
  /dev/sdv  [       25.00 GB]
  /dev/sdg  [       15.00 GB]
  /dev/sdw  [       20.00 GB]
  /dev/sdh  [       40.00 GB]
  /dev/sdx  [       20.00 GB]
  /dev/sdi  [       40.00 GB]
  /dev/sdy  [       15.00 GB]
  /dev/sdj  [       25.00 GB]
  /dev/sdz  [       40.00 GB]
  /dev/sdk  [       20.00 GB]
  /dev/sdl  [       20.00 GB]
  /dev/sdm  [       15.00 GB]
  /dev/sdn  [       40.00 GB]
  /dev/sdo  [       40.00 GB]
  /dev/sdp  [       25.00 GB]
  25 disks
  1 partition
  0 LVM physical volume whole disks
  1 LVM physical volume

From my understanding, powerpath should work with this array type.   Any suggestions on what I need to do to get powerpath to work?

Thanks in Advance.

Dynamox is correct, the EVA 4x00 series is not supported by EMC (and will not be supported via the RPQ process. From a previous post:

"The EVA4000 controller type is different from the other supported EVA models (3x00, 5x00 and 8x00).  PP doesn’t support the EVA4x00

i just checked in E-Lab and Powerpath 5.3 supports EVA3000, 5000 and 8000. I did not see any 4 thousand models.

PowerPath will not claim devices it's not designed to support. So you can use HP's multipathing software (Secure path ? ) or use Linux dm-mpio.

Thanks Dynamox and Conor for your help.   This does explain why powerpath is not working in this setup.   This  is definitely a  bummer... 

Thanks again
