Overview of DR Configuration Tasks
This section identifies the various configuration tasks that you must complete before running DR operations on Solaris 9 domains (which support only DR model 3.0). Note that it may not be necessary to perform all the tasks described in this section, depending on the types of devices on your system boards and the type of DR operation to be performed.
After you configure DR or whenever you make changes to the DR configuration, you must reboot your domain. If you want to minimize the number of domain reboots, determine which configuration tasks are applicable to your DR environment and then perform the appropriate set of configuration tasks before rebooting your domain.
1.If you intend to perform DR detach operations, enable the kernel cage, as explained in “To Enable the Kernel Cage” on page 17.
2.For devices, do the following:
■If you set network configuration parameters manually, make these settings permanent as described in “To Set Permanent Driver Parameters for Network Drivers” on page 17.
■If you have soc and pln devices, enable device suspension, as described in “To Enable Device Suspension for the soc and pln Drivers” on page 18.
■If you have
For details, see “To Specify an Unsafe Driver List” on page 18.
■If you have tape devices that are not supported by Sun Microsystems, make those devices
For details, see “To Make an Unsupported Tape Device
3.If you want to use multipathing, configure your domain for multipathing and run the appropriate multipathing software on the domain.
4.Reboot the domain to process the configuration changes.
Note – You must reboot the domain after any changes to the DR configuration. If you want to minimize the number of reboots, you may want to perform various configuration tasks then reboot the domain.
5.After the reboot completes successfully, review the /var/adm/messages file for messages that verify the DR configuration changes.
