'srp_daemon' or 'ibsrpdm' commands shows only SRP targets and not the LUNs

Solution Unverified - Updated -

Issue

  • We have assigned the LUNs from IBM FlashSystem storage array to RHEL 6.6 server using Infiniband HCAs. There are 5 LUNs exported from SAN/Storage side, and system is able to access it without any issues. But when we try to 'see' those LUNs via srp_daemon or ibsrpdm commands we see ports and not the LUNs.
    e.g.

    [root@test ~]# /usr/sbin/ibsrpdm -c -d /dev/infiniband/umad2
