Designing Disaster Tolerant High Availability Clusters, 10th Edition, March 2003 (B7660-90013)

Environment File Variables for MetroCluster/SRDF
Appendix B416
• symcfg.out – contains the results of symcfg list
command, used for model and revision information.
• symrdf.out – contains the results of symrdf query
commands run from the package control script.
• awk.out – contains the output from using awk to
parse the symrdf.out file.
• FORCEFLAG – forces a package to start
automatically under certain circumstances if this
file is present. The cmrunpkg packagename
command deletes this file, so it must be recreated
each time if you wish to start packages under these
circumstances.
RETRY Default: 5.
This is the number of times a SymCLI command is
repeated before returning an error. Use the default
value for the first package, and slightly larger numbers
for additional packages making sure that the total of
RETRY*RETRYTIME is approximately 5 minutes.
Larger values for RETRY may cause the start-up time
for the package to increase when there are multiple
packages starting concurrently in the cluster that
access the Symmetrix arrays.
RETRYTIME Default: 5.
This is the is the number of seconds between retries.
The default value of 5 seconds should be used for the
first package. The values should be slightly different
for other packages. RETRYTIME should increase by two
seconds for each package. The product of RETRY *
RETRYTIME should be approximately five minutes.
These variables are used to decide how often and how
many times to retry the Symmetrix status and state
change commands.
Larger values for RETRYTIME may cause the start-up
time for the package to increase when there are
multiple packages starting concurrently in the cluster
that access the Symmetrix arrays.
