Chapter 2: mx Commands 50

[--type CUSTOM|DISK|GATEWAY|SHARED_FILESYSTEM]

The type of device monitor.

[--probeSeverity nofailover|autorecover|noautorecover]

The failover behavior for the monitor. nofailover prevents failover of

virtual hosts when the monitored device fails. autorecover fails over the

virtual hosts, and when the device is restored, fails the virtual hosts back

to the original network interfaces. noautorecover fails over the virtual

hosts but does not fail them back after the device is restored. The default

is autorecover.

[--parameters <parameters>]

The available parameters depend on the type of monitor:

•

DISK device monitor. The parameter is a partition on the disk. The

monitor will attempt to read the first block on this partition to

determine whether the disk is operating normally.

•

GATEWAY device monitor. The IP address of the gateway device (such

as a router). The IP address must be on a different subnet than the

servers in the cluster.

•

CUSTOM device monitor. The parameter is a probe script. The

maximum length of the pathname is 512 characters.

•

SHARED_FILESYSTEM device monitor. The first parameter is the

volume (for example, psd1p6) containing the filesystem to be

monitored. The second parameter is the name of a file that the monitor

probe should open and attempt to read to determine the health of the

filesystem. The filename should be relative to the mount point of the

filesystem. When the filesystem is mounted, the mountpath will be

prepended to the filename to determine the complete filename path

that should be probed. The second parameter is optional.

[--ordering serial|parallel]

Whether HP Clustered File System enforces a strict ordering sequence

when it runs Start or Stop scripts. The default is serial, the strict ordering

sequence.

[--recoveryScript <script>]

A script that runs after a monitor probe has failed. The script attempts to

restore the device. The script pathname can be up to 512 characters long.
