Designing Disaster Recovery Clusters using Metroclusters and Continentalclusters, Reprinted October 2011 (5900-1881)

MON_NOTIFICATION_SYSLOG <0 or 1>
If you want notification messages to be logged on the system's console, uncomment the
MON_NOTIFICATION_CONSOLE variable and set it to 1. If the variable is not set, the
default value is 0.
MON_NOTIFICATION_CONSOLE <0 or 1>
If you want an automatic resynchronization upon link recovery, uncomment the
AUTO_RESYNC variable and set it to either 1 or 2. If the variable is not defined or
commented, the default value of 0 is used.
If AUTO_RESYNC is set to 0 (DEFAULT), the monitor will not try to do the resynchronization
from PVOL to SVOL. This setting will only send notifications.
If AUTO_RESYNC is set to 1, the monitor will split the remote BC if one is configured
from the mirror group before trying to do the resynchronization from PVOL to SVOL.
If AUTO_RESYNC is set to 2, the monitor will only do the resynchronization from PVOL
to SVOL when it finds the MON_RESYNC file in the package directory on the node that
the package is running. The monitor will not manage the remote BC prior to and after
the resynchronization. This setting is used if the user wants to manage the BC themselves.
To enable the Continuous Access resynchronization for AUTO_RESYNC=2, it is necessary
to create a file using the HP-UX command touch. For example:
# touch <dts/dts/dts_pkg_dir>/MON_RESYNC <0 or 1 or 2>
If you want an automatic resynchronization for the Delta Resync pair if the
monitor detects that the data is not being replicated to DC3 over Continuous Access
Journal (CAJ) pair due to either link or storage failures, uncomment the
AUTO_DELTA_RESYNC variable and set it to 1. If the variable is not defined or
commented, the default will be 0.
AUTO_DELTA_RESYNC <0 0r 1>
NOTE: While the Device Group Monitor (DGM) is used, the online package
re-configuration of the DGM parameters is not supported. The online package
re-configuration of the 3DC parameters is supported only for the following:
• AUTO_SVOLPSUS
• AUTO_SVOLPSUE
• AUTO_SVOLPFUS
• AUTO_PSUSSSSWS
• AUTO_PSUEPSUS
• AUTO_NONCURDATA
• AUTO_FENCEDATA_SPLIT
When DGM is not used, the online package re-configuration of all 3DC parameters
is supported.
b. Un-comment the service parameters for the Device Group Monitor and provide a unique
name to the service_name parameter. Do not edit the service_cmd parameter. It is
auto generated.
Eg:
service_name mcxpca_dgmonitor
service_cmd "/usr/sbin/DRMonitorXPCADevGrp
${DTS_dts/dts/dts_pkg_dir}/${SG_PACKAGE_NAME}_xpca.env"
service_restart none
service_fail_fast_enabled no
service_halt_timeout 300
