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.
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.
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 SMI-S CIMOM in Management
Server. The default timeout is 300 seconds. The recommended
minimum value is 20 seconds.
8. After customizing the control script file and creating the
environment file, and before starting up the package, do a syntax
check on the control script using the following command (be sure to
include the -n option to perform syntax checking only):
# sh -n <pkgname.cntl>
If any messages are returned, it is recommended to correct the
syntax errors.
9. Distribute Metrocluster Continuous Access EVA configuration,
environment and control script files to other nodes in the cluster by
using ftp or rcp:
# rcp -p /etc/cmcluster/pkgname/* \
other_node:/etc/cmcluster/pkgname
See the example script Samples/ftpit to see how to semi-automate
the copy using ftp. This script assumes the package directories
already exist on all nodes.
