Security Solutions

fence level is that if the package is running and a link goes
down, an array goes down, or the remote data center goes
down, then write(1) calls in the package application will
fail, causing the package to fail.
NOTE: The Continuous Access Journal is used for
asynchronous data replication. Fence level ascyn is used
for a journal group pair.
If the package is configured for three data centers (3DC),
this parameter holds the fence level of device group between
DC1 and DC2. As the device group between DC1 and DC2
is always synchronous, the fence level either “data” or
“never”. The fence level of device group between DC2 and
DC3 or DC1 and DC3 is always assumed to be “async”
and user need not mention it.
HORCMINST This is the instance of the Raid Manager that the control
script will communicate with. This instance of Raid Manager
must be started on all the nodes before this package can
be successfully started. (Note: If this variable is not exported,
Raid Manager commands used in this script might fail).
HORCMPERM This variable supports the security feature, RAID Manager
Protection Facility on the Continuous Access devices. (Note:
If the RAID Manager Protection Facility is disabled, set this
variable to MGRNOINST. This is the default value).
HORCTIMEOUT (Default = 360)
This variable is used only in asynchronous mode when the
horctakeover command is issued; it is ignored in
synchronous mode. The value is used as the timeout value
in the horctakeover command, -t <timeout>. The
value is the time to wait while horctakeover re-synchronizes
the delta data from the PVOL to the SVOL. It is used for
swap-takeover and SVOL takeover. If the timeout value is
reached and a timeout occurs, horctakeover returns the
value EX_EWSTOT. The unit is seconds.
In asynchronous mode, when there is an Continuous Access
link failure, both the PVOL and SVOL sides change to a
PSUE state. However, this change will not take place until
the Continuous Access link timeout value, configured in the
Service Processor (SVP), has been reached. If the
horctakeover command is issued during this timeout
period, the horctakeover command will fail if its timeout
value is less than that of the Continuous Access link timeout.
Therefore, it is important to set the HORCTIMEOUT variable
to a value greater than the Continuous Access link timeout
value. The default Continuous Access link timeout value is
5 minutes (300 seconds). A suggested value for
HORCTIMEOUT is 360 seconds.
During package startup, the default startup timeout value of
the package is set to NO_TIMEOUT in the package ASCII
file. However, if there is a need to set a startup timeout
value, then the package startup timeout value must be
greater than the HORCTIMEOUT value, which is greater than
the Continuous Access link timeout value:
Pkg Startup Timeout > HORCTIMEOUT >
Continuous Access link timeout value
