Issue/Introduction

CA VM:Secure (TM) Version 03.2 RSU-2001

When trying to relabel a volume, minidisks that are defined over the 65520 limit is not changed.

Entering command:   VMSECURE CHGVOLNM VM481A VX481A LABEL

The operation fails with message:

VMXCHG0752W Skipping volume label change for the 0777 minidisk of user V077229 due to error updating directory entry.
VMXDYG0121E Error 124 from DIAGNOSE X'84' processing.

Minidisks defined and sized to fit under the 65520 cylinder limit works okay.

The device type specified in the DASD CONFIG are as follows

  DEVTYPE 3390-216 3390 4096 261555 

And the volume is included in a pool

  SUBPOOL LXTPOOL  LINEAR   LOWEND *    

  VOLUME  VM481A 3390-216                    
    EXTENT       0       0   * ALLOC        
    EXTENT       1  261554   LXTPOOL

Using DIAGNOSE X'84' to alter minidisk extents (RMDISK
operation) on an EAV volume with cylinder extent definitions
crossing the or being greater than the 65k cylinder boundary
will fail with RC=124 or RC=125.
