SHADOW_MBR_TMO

   SHADOW_MBR_TMO controls the amount of time the system tries to
   fail over physical members of a shadow set before removing them
   from the set. The SHADOW_MBR_TMO parameter replaces the temporary
   VMSD3 parameter used in prior releases.

   The SHADOW_MBR_TMO parameter is valid for use only with Phase II
   of Volume Shadowing for OpenVMS. You cannot set this parameter
   for use with Phase I, which is obsolete.

   Use the SHADOW_MBR_TMO parameter (a word) to specify the number
   of seconds, in decimal from 1 to 65,535, during which recovery
   of a repairable shadow set is attempted. If you do not specify
   a value or if you specify 0, the default delay of 120 seconds is
   used.

   Because SHADOW_MBR_TMO is a dynamic parameter, you should use the
   SYSGEN command WRITE CURRENT to permanently change its value.

   SHADOW_MBR_TMO is a DYNAMIC parameter.
