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;
