Description

LifeKeeper resources exist in relationship to one another. Two resources may be unrelated or they may be in a dependency relationship. In a hierarchy, a resource may have several resources depending upon it,and it may depend upon several resources. Each resource also relates to a like resource on the paired system with a shared equivalency. This shared equivalency ensures that a resource is active on only one system at a time. Equivalency object also indicates priority of the system for the resource. This priority value determines the order of cascading failover. A higher priority system has precedence over a lower priority system in recovering the resource. A priority value of 1 is the highest. The higher the numerical value the lower the priority. Two systems can’t be assigned same priority for a resource. Valid range is 1 to 1024.

Exit Codes

All commands exit 0, if successful, and a nonzero code and prints to standard error, for failure. The following exit codes could be returned by these commands:

0	The operation has succeeded.
1	A system call or library call has internally returned failure.
2	A user-specified syntax error occurred.
3	LifeKeeper internal error.
4	A request to perform an operation on an object that already exists.
5	An argument specified is illegal.
6	Index out-of-range.
7	A request has been made on an object that does not exist.
8	A request was made to delete a resource instance on which another non-deleted resource instance depends.
9	An attempt to communicate with another system failed.
