Event Notification

Event notification is a feature that keeps you aware of dynamic state changes, such as creation of a metadevice, a change in a metadevice status, or device errors. Event notification takes care of the following:

• More than one administrator at a time, if necessary, can run DiskSuite Tool on the same host with the assurance that state changes are propagated to each instance of DiskSuite Tool.

• When running multiple instances of DiskSuite Tool on the same host, event notification ensures that proper locking occurs to prevent one instance of DiskSuite Tool from overwriting the changes made by another. When one DiskSuite Tool has an uncommitted action, it has a "lock" until a commit occurs or the device is removed.

  Note -

  Though you can run multiple instances of DiskSuite Tool on the same host, it is best to avoid doing so.

• You can run both DiskSuite Tool and the command line utilities together. Event notification is able to pass state changes from the command line to DiskSuite Tool.

  Note -

  DiskSuite Tool provides the same functionality as the ssaadm(1M) command to start and stop a disk. However, do not use DiskSuite Tool and the ssaadm(1M) together. Doing so could cause DiskSuite Tool to incorrectly display a disk`s status. Always use one or the other to both stop and start a disk.
