NOTE: If the EMS disk monitor is used as a package resource, then the NO_TIMEOUT value must not be used. If used, the package shutdown hangs if there is no access from the host to the package disks.
5.Copy the environment file template /opt/cmcluster/toolkit/SGCA/caeva.env to the dts/dts/dts_pkg_dir directory specified earlier.
# cp /opt/cmcluster/toolkit/SGCAEVA/caeva.env \ /etc/cmcluster/pkgname
6.Edit the environment file, caeva.env, as follows:
a.Uncomment the PKGDIR variable and set it to the full path name of the directory where this environment file has been placed. This directory must be unique for each package. For example:
PKG_DIR=“/etc/cmcluster/pkgname”
b.Uncomment the CLUSTER_TYPE variable and set it to metro.
c.Set the DT_APPLICATION_STARTUP_POLICY variable to one of following policies: Availability_Preferred, or Data_Currency_Preferred.
d.Set the WAIT_TIME variable to the timeout, in minutes, to wait for completion of the data merge from source to destination volume before starting up the package on the destination volume. If the wait time expires and merging is still in progress, the package will fail to start with an error that prevents restarting on any node in the cluster.
e.Set the DR_GROUP_NAME variable to the name of DR Group used by this package. This DR Group name is defined when the DR Group is created.
f.Set the DC1_STORAGE_WORLD_WIDE_NAME variable to the world wide name of the EVA storage system which resides in Data Center 1. This WWN can be found on the front panel of the EVA controller, or from command view EVA UI.
g.Set the DC1_SMIS_LIST variable to the list of Management Servers which resides in Data Center 1. Multiple names are defined using a comma as a separator between the names.
If a connection to the first management server fails, attempts are made to connect to the subsequent management servers in the order that they are specified.
h.Set the DC1_HOST_LIST variable to the list of clustered nodes which resides in Data Center 1. Multiple names are defined using a comma as a separator between the names.
i.Set the DC2_STORAGE_WORLD_WIDE_NAME variable to the world wide name of the EVA storage system which resides in Data Center 2. This WWN can be found on the front panel of the EVA controller, or from command view EVA UI.
j.Set the DC2_SMIS_LIST variable to the list of Management Server, which resides in Data Center 2. Multiple names are defined using a comma as a separator between the names. If a connection to the first management server fails, attempts are made to connect to the subsequent management servers in the order that they are specified.
k.Set the DC2_HOST_LIST variable to the list of clustered nodes which resides in Data Center 2. Multiple names are defined using a comma as a separator between the names.
l.Set the QUERY_TIME_OUT variable to the number of seconds to wait for a response from the
7.Distribute this Metrocluster environment file to other nodes in the cluster under the same directory by using FTP, RCP or SCP.
