| consistency groups. (Consistency groups are required for M by N |
| configurations.) |
| If CONSISTENCYGROUPS is set to 1, AUTOSWAPR2 cannot be set to |
| 1. Ensure that you have the minimum requirements for Consistency |
| Groups by referring to Metrocluster release notes. |
DEVICE_GROUP | This variable contains the name of the Symmetrix device group for the |
| package on that node, which contains the name of the consistency |
| group in an M by N configuration. |
DTS_PKG_DIR | 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 might cause the |
| 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 must be used for the first package. The values must be |
| slightly different for other packages. RETRYTIME must increase by two |
| seconds for every package. The product of RETRY * RETRYTIME 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 RETRYTIME might cause the |
| |
| 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. |
