Table 25-51 lists the system processing and the actions to be taken by the HiRDB administrator when errors occur.
Table 25-51 System processing and the HiRDB administrator's actions in the event of an error (using the system switchover facility)
Error | System processing | HiRDB administrator's action | |
---|---|---|---|
A server failure occurred (only HiRDB terminated abnormally). | Server mode | As specified in the switchtype operand1 of HA monitor or Hitachi HA Toolkit Extension. | Check the cause of the error on the basis of the output message. Refer to 18. Error Handling Procedures,and take appropriate action. |
Monitor mode | Does not perform system switchover. Restarts HiRDB on the system resulting in the error. | ||
A system failure occurred. | Performs system switchover and restarts HiRDB on the switchover destination system. However, depending on the type of system failure, system switchover may not be performed. A cluster software specification determines whether or not system switchover will be performed; for details, see the cluster software documentation. | Check the cause of the error on the basis of the output message. Refer to 18. Error Handling Procedures or the applicable manual, and take appropriate action. | |
HiRDB restart failed | Server mode | As specified in the switchtype operand1 of HA monitor or Hitachi HA Toolkit Extension. | |
Monitor mode | As specified in the pd_ha_restart_failure operand.2 | ||
System switchover failed | Terminates the system. |
When system switchover occurs, VERITAS Cluster Server takes all resources on the running system offline, starting with the parent resource, and then places the resources on the standby system online starting with the child resources. If an unexpected system switchover occurs, take the following actions as necessary to return the running system to its original server machine:
When HiRDB terminates abnormally, restart HiRDB on the running system. Also, when a dummy file for a HiRDB_x type resource is deleted, the resource is placed in error status and HiRDB terminates forcibly. Actions to take are described below:
After resolving the error, use a planned system switchover to switch the system back to the normal BES unit (return to normal status from alternating status). For details about planned system switchover, see 25.14(2) Standby-less system switchover (1:1) facility.
After resolving the error, use a the planned system switchover to switch the system back to the regular unit (return to normal status from standby status). For details about planned system switchover, see 25.14(3) Standby-less system switchover (effects distributed) facility.
