Conﬁguring EMS HA-ATM for Remote Recovery (Using MC/ServiceGuard)

Chapter 6132

Step 7. Select the Modify Package Resource Dependencies... button.

This opens the “Package Resource Dependencies” window.

Step 8. Select the Add Resource... button.

Step 9. Step through the hierarchy of classes until you get to the appropriate

class level. To do this, in the “Resource classes” list, select the following

items, in this order:

a. net

b. interfaces

c. switched

d. atm

This opens the “Resource Parameters” window.

Note that you must specify the same resource name on all of the systems

you want to participate in remote recovery.

Also, multiple packages can use the same resource name.

Step 10. In the “Resource Up Values” list, ensure that UP is the only value listed.

If UP isn’t listed in “Resource Up Values,” move it from the “Available

Resource Values” list to “Resource Up Values.”

Step 11. Select the OK button until you can exit SAM.

Note that when you specify an ELAN interface resource as a package

resource dependency, the monitoring daemon (hatmmon) is automatically

started for that interface. The daemon continues to run as long as the

MC/ServiceGuard cluster is running. If you remove an ELAN interface

as a package resource dependency, the hatmmon daemon for that ELAN

interface stops running 60 minutes later (unless you use the kill -15

command to stop the daemon before the 60 minutes elapse).

Step 12. Go to the next section, “Verifying the Remote Recovery Conﬁguration”.
