SHADOW_SYS_TMO

   The SHADOW_SYS_TMO parameter has the following two distinct uses:

   o  At system boot time, when this is the first node in the
      cluster to boot and to create this specific shadow set. If the
      proposed shadow set is not currently mounted in the cluster,
      use this parameter to extend the time a booting system waits
      for all former members of the shadowed system disk to become
      available.

   o  Once the system successfully mounts the virtual unit and
      begins normal operations. In this usage, the SHADOW_SYS_
      TMO parameter controls the time the operating system waits
      for errant members of a system disk. (Use the SHADOW_MBR_TMO
      parameter to control the time the operating system waits for
      the errant members of an application disk.)

   This parameter applies only to members of the system disk shadow
   set. All nodes using a particular system disk shadow set should
   have their SHADOW_SYS_TMO parameter set to the same value once
   normal operations begin.

   The default value is 120 seconds. Change this parameter to a
   higher value if you want the system to wait more than the 120-
   second default for all members to join the shadow set. You can
   set the parameter value to 120 through 65,535 seconds.
