When there is a stopped unit, you can execute system switchover for the system manager unit by specifying the following operands:
Table 25-56 shows how to specify these operands and the actions HiRDB takes during system switchover.
Table 25-56 Operands related to reduced activation and actions HiRDB takes during system switchover
Condition | Actions HiRDB takes when system switchover occurs for the system manager unit | |
---|---|---|
pd_start_level specification value | pd_start_skip_unit specification | |
0 (default value) | ![]() | If there is a stopped unit, system switchover for the system manager unit fails. |
1 | Not specified | Even if there is a stopped unit, system switchover for the system manager unit executes. However, a wait occurs for receipt of a startup processing completion notice from each unit. The startup time limit is specified in the pd_reduced_check_time operand (default value is 20 minutes). |
Specified | Even if there is a stopped unit, system switchover for the system manager unit executes. No checking wait time occurs. |
When you specify the pd_start_skip_unit operand, you must terminate HiRDB. Therefore, you should consider the other method if your system must remain active around the clock.
