3.5.1 Matrix Server Command Reference

Chapter 2: mx Commands 62

[--frequency <seconds>]

The interval at which the monitor probes the device. For DISK and

SHARED_FILESYSTEM device monitors, the default is 30 seconds. For

CUSTOM device monitors, the default is 60 seconds.

[--probeSeverity nofailover|autorecover|noautorecover]

The failover behavior for the monitor:

With NOFAILOVER, when the monitor probe fails, the virtual host does not

fail over.

With AUTORECOVER, the virtual host fails over when a monitor probe fails.

When device access is recovered on the original node, failback occurs

according to the virtual host’s failback policy. This is the default.

With NOAUTORECOVER, the virtual host fails over when a monitor probe

fails and the monitor is disabled on the original node, preventing automatic

failback. When the monitor is reenabled, failback occurs according to the

virtual host’s failback policy.

[--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.
