3.1.2 Matrix Server Command Reference

Chapter 2: mx Commands 60

[--type CUSTOM|DISK|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.

•

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 Matrix Server 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.

[--recoveryTimeout <seconds>]

The amount of time to wait for the Recovery script to complete.
