PATH Has been modified to include the path name of the Symmetrix SymCLI
commands. This should be set to the default location of /usr/symcli/
bin unless you have changed the location.
PKGDIR If the package is a legacy package, then this variable contains the full
path name of the package directory. If the package is a modular
package, then this variable contains the full path name of the directory
where the Metrocluster SRDF environment file is located.
RDF_MODE Default:
This parameter defines the data replication modes for the device group.
The supported mode are “sync” for synchronous and “async” for
Asynchronous. If RDF_MODE is not defined, synchronous mode is
assumed.
RETRY Default: 60.
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.
SYNCTIMEOUT Default: 0.
This variable denotes the number of seconds to wait for resync to
complete after failback of the Symmetrix device group. If you set the
value to 0, then the package will start after failback without waiting
for resynchronization to complete. If you set the value to 1, then the
package waits till resynchronization is complete before starting up. If
SYNCTIMEOUT is set to any value from 5 to 36000, then the package
will wait the specified time for resynchronization to complete after
failback. If resynchronization does not complete even after the specified
time, then the package will fail to start up; if resynchronization
completes before that, then package will start up immediately after
resynchronization is complete.
