Clearing resource model alerts

In a Db2 pureScale® environment, hardware- or software-related alerts can exist on the status table for members, cluster caching facilities (CFs), and for hosts. In some cases, the alert conditions are transient so the alert field might clear itself; however, in other cases, the alert field remains set until the administrator resolves the problem and manually clears the alert .

About this task

When this command is run, all alerts for the instance on the specified member, cluster caching facility, or host are cleared.

To perform this task, you must be a user in the SYSADM, SYSMAINT, or SYSADM group.

Procedure

To clear alerts for a member, cluster caching facility, or host, issue this command:
```
db2cluster -clear -alert  [-member member-id | -cf cf-id | -host host-name]
```
To clear alerts while logged on as root, issue this command:
```
db2cluster -clear -alert -instance <instance_name>
```

Results

Once the command completes, the system might or might not take a specific action related to the component that had its alert cleared. In some cases, the member is returned to its home host, but if a restart light failure caused the alert, no action is taken.
