HP Serviceguard Metrocluster with EMC SRDF for Linux B.01.00.00

“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 ensuring that the
total of RETRY*RETRY_INTERVAL is approximately five minutes.
Larger values for RETRY might cause the start-up time for the package
to increase when there are multiple packages starting concurrently
in the cluster that accesses the Symmetrix arrays.
RETRY_INTERVAL Default: 5.
This is the is the number of seconds between retries. The default
value of 5 seconds must be used for the first package. The values
must be slightly different for other packages. RETRY_INTERVAL must
increase by two seconds for each package. The product of RETRY
* RETRY_INTERVAL must 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 RETRY_INTERVAL might cause the start-up time for the
package to increase when there are multiple packages starting
concurrently in the cluster that accesses 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.
