Solution In Progress - Updated -

Issue

  • RHEL 6.5 system lose access to IBM IMM after reset, ipmi_thread spins
  • After resetting the IMM from the web interface or with ipmitool mc reset cold, IPMI commands no longer operate, and the kipmi0 process takes 100% CPU
  • In particular IBM's DSA tool does not work after an IMM reset because it uses IPMI, amongst other methods, to gather data.

Environment

  • Red Hat Enterprise Linux 6
  • IBM xSeries with original model IMM (not IMM2)
