Monitoring Disks
Each package configuration includes information about the disks that
are to be activated by the package at startup. If monitoring is used, the
health of the disks is checked at package startup. The package will fail if
the disks are not available.
When this happens, the package may be restarted on another node. If
auto_run is set to yes, the package will start up on another eligible
node, if it meets all the requirements for startup. If auto_run is set to no,
then the package simply halts without starting up anywhere else.
The process for configuring disk monitoring is described in “Creating a
Disk Monitor Configuration” on page 239.
