Not able to see all paths for luns after representing it from SAN

Solution Verified - Updated -

Issue

  • The history of this issue is a scenario where there were originally 8 paths per LUN and 4 paths removed per LUN. Then 4 new paths were added in place of the removed paths. The removal and additions of the paths occurred in the storage backend prior to the OS removal of paths and now we are in the state described in this ticket. We are currently working on a test system (UCS blade) and have to replicate our recovery efforts from this system to 70+ production servers without a reboot.

Environment

  • Red Hat Enterprise Linux 6
  • Cisco UCS blade
  • FCOE
  • NETAPP
