OA51499: ABENDE37-08 WHEN EXTENDING TO A VOLUME WITH NO SPACE. Z/OS2.2 ONLY

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• ABENDE37-08 when extending to a volume with insufficient space.
  The result is an overwrite of the VTOC track start+1. Any
  following requests to the VTOC fail with a CVSTAT x'7F' (127)
  I/O error.
  
  It seems this is triggered by an ABEND EXIT that IGNOREs the
  ABEND.

Local fix

• Disable the Secondary Space Relief (SSR) function.
  
  Turning off SSR can result in experiencing the issue described
  by OA51474.  It is highly recommended that the ++APAR for
  OA51474 be applied as well OR Restore UA82730.  It can be found
  in the testcase.boulder.ibm.com server in the fromibm/mvs
  directory as AA51474.HDZ2220
  
  This will require an IPL.
  
  F DEVMAN,DISABLE(SSR) on the z/OS 2.2 images (this does NOT
  persist across IPLs).
  
  - OR -
  
  Permanently disable the SSR function until the PTF is available
  by updating the DEVSUPxx parmlib member with;
  
  DISABLE(SSR)
  
  Make this the LAST parameter if you share Parmlib across a
  SYSPLEX with different Z/OS levels. This parm is only recognized
  by z/OS 2.2
  
  Expect a IEA252E message in pre z/OS 2.2 images as this
  parameter is not supported there.
  
  Then issue the SET DEVSUP=(xx,yy) or SET DEVSUP=xx command per
  your installation.
  
  ---------------------------------------------------------------
  
  Check to ensure SSR is not enabled via;
  F DEVMAN,REPORT
  
  When disabled, SSR should NOT display under OPTIONS;
