OpenVMS Release Notes
4. HOST_REDUNDANT
NOHOST_REDUNDANT
Turns on and off the capability to redirect
the host to the redundant unit copy for the
original requested unit data after the
controller is unable to submit data from the
original unit to the host. This switch is used
in conjunction with the SET
unit-number
command.
In dual-redundant configurations, when a
controller in earlier ACS versions was
unable to retrieve data from a failed unit
upon request from a host, some host systems
(particularly Tru64 UNIX with Logical
Storage Manager) continuously waited for
data to be returned from the controller
without automatically retrieving the same
data from the dual-redundant unit copy.
Simultaneously, the controller continuously
attempted to retrieve the data from the failed
unit without success.
