DR Models

There are two models of DR available for the Sun Enterprise 10000 system. DR model 2.0 is sometimes referred to as “legacy DR,” and DR model 3.0 is referred to as “next generation DR.” The following table shows the different versions of the Solaris operating environment and the SSP software that are used with DR models

2.0 and 3.0:

DR Model

Solaris Software Versions

SSP Software Versions

 

 

 

2.0

Solaris 5.1, 6, 7, and 8

3.3, 3.4, or 3.5

3.0

Solaris 8 10/01 and 02/02,

3.5 only

 

Solaris 9

 

 

 

 

Domains running version 9 of the Solaris software support only DR model 3.0, and version 3.5 of the SSP software is required.

Only one model of DR can run within a domain at a time. To check the version of DR that is running, use the domain_status command with its -moption (available only on domains running version 3.5 of the SSP software). Make sure to verify the DR model before you execute any DR commands. The following is an example of the domain_status(1M) output. The DR-MODELcolumn indicates which model is enabled

# domain_status -m

According to this output, domain A is running Solaris version 8 software (OS 5.8) with DR model 2.0 enabled; domain B is running Solaris version 8 software with DR model 3.0 enabled; domain C is running Solaris version 7 software (OS 5.7) with DR model 2.0 enabled; and domain D is running Solaris version 9 software (OS 5.9) with DR model 3.0 enabled.

Only certain commands are available in each model, and if you execute a command that is not supported, an error message appears on the console.
