Physical Data Replication for ContinentalClusters Using EMC SRDF
Setting up a Recovery Package on the Recovery Cluster
Chapter 7 343
6. Copy the package files from the primary cluster to a bkpkgXXX
directory, and rename it to <backup_pkg_name>.cntl and
<backup_pkg_name>_srdf.env. Edit the recovery package control file
from the primary cluster for the secondary cluster. Change the
subnet, relocatable IP, and nodes.
Be sure to set AUTO_RUN to NO in the package ASCII file.
7. Edit the recovery package environment file
<bk_pkg_name>_srdf.env as follows:
a. Add the path for SymCLI software binaries.
b. Make sure that all AUTO* variables are uncommented.
c. Uncomment the PKGDIR variable and set it to the full path name
of the directory where the control script has been placed. This
directory must be unique for each package and is used for status
data files. For example, set PKGDIR to
/etc/cmcluster/<backup_pkgname>.
d. Uncomment the DEVICE_GROUP variable and set them to the
Symmetrix device group names given in the ’symdg list’
command. The DEVICE_GROUP variable may also contain the
consistency group name if using a M by N configuration.
e. Uncomment the RETRY and RETRYTIME variables.
f. Make sure the CLUSTER_TYPE variable is set to continental.
NOTE The mount point i.e., /pkgCCA and VG are the same in both clusters.
8. Edit the remaining application package control script variables in
the package control script (VG, LV, FS, IP, SUBNET, SERVICE_NAME,
SERVICE_CMD and SERVICE_RESTART) according to the needs of the
application. See the MC/ServiceGuard manual for more information
on these variables. Change the Subnet IP from ftp copy.
9. Verify that each host in both clusters in the continental cluster has
the following files in the directory /etc/cmcluster/<pkg_name>:
<backup_pkg_name>.cntl (continental cluster package control
script)
<backup_pkg_name>.conf (MC/ServiceGuard package ASCII config
file)
