[openib-general] srp initiator device discovery

[vishal]

Hi,

   I have srp initiator installed with OFED-1.1, and another machine
with SRP target (IBGOLD). I started the srp daemon to discover the
target devices, and then ran fdisk -l to see the list. The list (below)
shows duplicate devices :-

Disk /dev/sdb: 2199.0 GB, 2199023255552 bytes
255 heads, 63 sectors/track, 267349 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Disk /dev/sdb doesn't contain a valid partition table

Disk /dev/sdc: 2199.0 GB, 2199023255552 bytes
255 heads, 63 sectors/track, 267349 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System

Disk /dev/sdd: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System

Doing some tests I found that sdb=sde, sdc=sdf, and sdd=sdg (obvious).

I also tested the device discovery after creating an md device on the
target side, and found that the initiator doesn't take into account the
presence of an md device. Is this the expected behaviour ?

Thanks for your time!
