ENABLE_ACCESS_PATH=connection-names
ENABLE_ACCESS_PATH=ALL (default)
DISABLE_ACCESS_PATH=connection-names
DISABLE_ACCESS_PATH=ALL
Specifies the access path. It can be a single specific host ID, multiple host IDs,
or all host IDs (ALL). If multiple hosts exist on the same bus, use this switch
to restrict hosts from accessing certain units. This switch limits visibility of
specific units from certain hosts. For example, if two hosts are on the same
bus, you can restrict each host to access only specific units.
Caution: If the storage subsystem has more than one host connection, the
access path must be specified carefully to avoid giving undesirable host
connections access to the unit. The default condition is that access paths to all
host connections are enabled. To restrict host access to a set of host
connections, specify
DISABLE_ACCESS_PATH=ALL if the unit is added,
then use the SET unit-number command to specify the set of host
connections that are to have access to the unit.
Enabling the access path to a particular host connection does not override
previously enabled access paths. All access paths previously enabled are still
valid; the new host connection is simply added to the list of connections that
can access the unit.
The procedure of restricting access by enabling all access paths and then
disabling selected paths is particularly
not recommended because of the
potential data and security breach that occurs if a new host connection is
added.
FAKE_PR
Note: Use the FAKE_PR switch for maintenance or recovery operations only.
If set on a unit, allows the controller to signal to host systems implementing
persistent reservations that persistent reservations are lost. (Lost persistent
reservations can occur as a result of mirrored cache reconfiguration or
maintenance activities, such as cache module replacement.) After the
FAKE_PR switch is invoked, the host may reset persistent reservations
against all of its units in the storage system. After successful communication,
the host recreates persistent reservations that were lost.
