IT33763: SPECTRUM CONTROL GUI SHOWS IN PROBE LOG FOR STORAGE: ERROR READING LOG-FILE C:/PROGRAM FILES/IBM/TPC/DEVICE/LOG\LOG FILE NAME.

APAR status

• Closed as program error.

Error description

• Agentless server creation fills in the T_RES_ELEMENT_PROBER
  status use usless HBA entries and it never deletes them
  afterwards.
  The DB2 table: T_RES_ELEMENT_PROBE_STATUS show a
  very high nimber of rows e.g. 102783852 rows.
  The high numbers
  of rows slow down the probes because of query/update/insert
  into that table.
  As a result, the Fabric Manager Service cannot
  start in 10 minutes and the probe are failing on data server
  side with this error message.
  They are running in Device Server
  only but the Data Server could not get the job
  status:

  * IBM Spectrum Control users who monitor storage subsystems    *
  * with thousands of host connections defined                   *

  * PROBLEM DESCRIPTION:                                         *
  * Redundant and unnecessary entries are created in the         *
  * database                                                     *
  * for the WWPN in host connection definitions, which makes the *
  * database grow over 1 GB large.  Then the SQL queries running *
  *                                                              *
  * against that table become very slow.                         *
  *                                                              *
  * Agentless server creation fills in the status with HBA       *
  * entries                                                      *

  * RECOMMENDATION:                                              *

  ****************************************************************
  Fix the code so the database contains proper entries to link a
  WWPN only to the host it belongs.
