Setting up Disk Monitoring
HP Serviceguard for Linux includes a Disk Monitor which you can use to
detect problems in disk connectivity. This lets you fail a package from
one node to another in the event of a disk link failure. To identify the set
of disks you wish to monitor, you run a script after all packages are
configured. (The script is run again any time you add, change or remove
packages.)
The process for configuring disk monitoring is described in “Creating a
Disk Monitor Configuration” on page 206.
For information on configuring lock LUNs, see “Setting up the Lock
LUN” on page 138.
