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.
