Symptoms

Migration fails with:
SLS6667I Request purged:Migrate VTVs MVC:mmmmmm VTV:vvvvv1  vvexp1 is not a valid VTV
SLS6667I Request purged:Migrate VTVs MVC:mmmmmm VTV:vvvvv2  vvexp2 is not a valid VTV
SLS6667I Request purged:Migrate VTVs MVC:mmmmmm VTV:vvvvv3  vvexp3 is not a valid VTV

Drain/Reclaim fails with:
 SLS6638I MVC mmmmmm SELECTED FOR RECLAIM OUTPUT VTSS:vtssname STORCL:storclas ACS:vle_subsys
****** MIGRATE/MOVE MVC:mmmmmm VTV:vvvvv1  vvexp1 IS NOT A VALID VTV *****
****** MIGRATE/MOVE MVC:mmmmmm VTV:vvvvv2  vvexp2 IS NOT A VALID VTV *****
****** MIGRATE/MOVE MVC:mmmmmm VTV:vvvvv3  vvexp3 IS NOT A VALID VTV ***** 

Scenario:

  1. RG0000 previously existed as a VTV, with DELSCR(YES) in effect.
  2. RG0000 was migrated to VMVC VME600.
  3. RG0000 was scratched.
  4. VMVC VME600 was drained or reclaimed, but RG0000 was not deleted from the VMVC (working as designed).
  5. VOLPARM definitions were modified so that RG0000 was redefined as a different type of (non-virtual) media; e.g. defined as T10K.  SET VOLPARM allows this since RG0000 is not a valid VTV and it does not exist upon any MVC, according to the CDS. It does still physically exist on VME600 much like it would still physically exist on a real MVC, until it is overwritten.
  6. VME600, now 100% available, is selected for output for migration (VTV RG0004). Fails with the SLS6667I error; e.g.

SLS6667I Request purged:Migrate VTVs MVC:VME600 VTV:RG0004  RG0000 is not a valid VTV

Changes

  1. A VTV was migrated to a VMVC (mmmmmm)
  2. The VTV expired and was scratched (vvexp1).
  3. The VMVC (mmmmmm) was drained (Note: VTV vvexp1 is intended to remain on the VMVC in the VLE until overwritten)
  4. The VTV (vvexp1) is redefined as a non-virtual volume (e.g. 9840, T10000, etc).
