IV85545: DIAG INTERRUPTION FORCES REBOOT TO TAKE CONTROL OF DEVICE BACK. APPLIES TO AIX 7100-04

APAR status

• Closed as program error.

Error description

• If a diag command gets ran on a device and then the diag
  process gets interrupted, there is no way to reconfigure
  that devices an take the control back except a reboot.
  # ps -ef | grep diag | grep -v grep
  # <<<<< diag proc is gone
  # lsdev -Cc adapter | grep fcs0
  fcs0   Diagnose 01-08 FC Adapter
  #      ^^^^^^^^
  # /usr/lib/methods/ucfgdiag -l fcs0
  # lsdev -Cc adapter | grep fcs
  fcs0   Defined   01-08 FC Adapter
  # cfgmgr -l fcs0
  Method error (/usr/lib/methods/cfgefscsi -l fscsi0 ):
  0514-061 Cannot find a child device.

  fscsi0    Available 01-08-02    FC SCSI I/O Controller
  

Local fix

• Reboot the system.
  

Problem summary

• When a terminal is closed(i.e. disconnect a connection of the
  terminal) during diag execution to fcs, fcs remains in Diagnose
  state. The child device of fcs should be recovered by
  re-configuring like rmdev/cfgmgr, however, the status cannot
  become Available unless system reboot.
  

Problem conclusion

• Modified the code to fix this problem.
  

Temporary fix
