IT36919: BROCADE REST-API SWITCH, NEVER BECOMES UNDETECTABLE AND CANNOT BE DELETED ALONE FROM IBM SPECTRUM CONTROL

IBM Spectrum Control 5.4.5.2 (December 2021)

APAR status

• Closed as program error.

Error description

• When a switch is no longer in use, the External process doing
  the pobe will just fail to connect to it, return an error, and
  will not create any output file.
  The probe's state will be Failed, but the switch will remain as
  DETECTABLE in IBM Spectrum Control
  The probes of the other switches in the Fabric set some link
  entities (port2port ) to UNDETECTABLE, but this is not enough,
  and when trying to delete the out of use switch from IBM
  Spectrum Control, the cleanup code still finds links
  between that switch and the rest of the switches, and delete
  them all.

  This APAR makes it possible for a switch to be deleted from
  Spectrum Control alone, independent of all the other
  switches in the fabric, when it is taken out from the fabric.
