OA66459: MSGIEF336I JOB CANCELLED BY ALLC_OFFLN INSTALLATION EXIT WITH JES3 AND TS7700 AND JES3 ALLOCATION ASSIST ENABLED

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• Any JES3 users with TS7700 and JES3 Allocation Assist function
  specified in DEVSUPxx parmlib member JES3_ALLOC_ASSIST=YES where
  their clusters being used do not start with cluster 0 or if
  their clusters being used start with cluster 0 but there are
  gaps, for example, clusters 0, 1, 4, 5, 6, 7 allocations may
  fail with MSGIEF336I JOB CANCELLED BY ALLC_OFFLN INSTALLATION
  EXIT or may go into allocation recovery IEF877I to vary a
  device online or may hang.
  Users Affected: users joining or unjoining clusters where
  the first cluster is not cluster0 or first one is cluster0
  but there are gaps, are running JES3 ONLY, with DEVSUPxx
  parameter JES3_ALLOC_ASSIST=YES
  

Local fix

• BYPASS/CIRCUMVENTION:
  create a new DEVSUPNN parmlib member, copy current DEVSUPxx to
  the new one and add:
  JES3_ALLOC_ASSIST=NO
  Then issue SET DEVSUP=NN where NN is the new DEVSUPNN created
  
  RECOVERY ACTION:
  rerunning the job will normally run successfully
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of TS7700 Virtualization Engine        *
  *                 D/T3957 and D/T3948 and are running in JES3  *
  *                 environment only.                            *
  ****************************************************************
  * PROBLEM DESCRIPTION: In Jes3 environment with TS7700 and     *
  *                      JES3_ALLOC_ASSIST=YES is specified in   *
  *                      DEVSUPxx member of SYS1.PARMLIB, if the *
  *                      first cluster in the composite library  *
  *                      is not named cluster 0 or if the first  *
  *                      cluster is named cluster 0 but there    *
  *                      are gaps in the names, for example cl0, *
  *                      cl1,cl4,cl5, device services may return *
  *                      a list of libpool ids that include the  *
  *                      distributed libraries incorrectly.      *
  *                      This can cause JES3 to build LDXlibid,  *
  *                      LDElibid entries in the JES3 deck       *
  *                      incorrectly.  When this happens some    *
  *                      tape allocations may fail because these *
  *                      invalid library names are returned in   *
  *                      the device pool list to allocation.     *

Problem conclusion

• Code was updated in LIBSERV POOLIST request to correctly return
  a list of device pool ids with the correct associated
  distributed library names.
