NAME

diskmond - EMS Disk Resource Monitor daemon

SYNOPSIS

diskmond [-l][-d]

DESCRIPTION

The

diskmond daemon monitors the status of physical devices and logical volumes conﬁgured in the

Logical Volume Manager (LVM). It is an Event Monitoring Services (EMS) monitor.

diskmond includes a resource dictionary ﬁle (

/etc/opt/resmon/dictionary/diskmond.dict

)

which is used by EMS to identify resources for monitoring.

Options

diskmond recognizes the following command-line options:

-l Write a syslog message any time a monitored resource changes value. If this option is not

speciﬁed, and the syslog notiﬁcation type was not selected for the monitored resource in the

GUI, no syslog messages are logged for value changes. The default diskmond.dict does not

specify this option.

-d Turn on daemon debugging and tracing messages. This allows detailed information to be

logged to the /var/opt/resmon/log/diskmond.log

ﬁle. WARNING: This ﬁle grows

without bound. Only use this option if you really need a trace. Debugging and tracing is off by

default.

RESOURCES

The EMS Disk Resource Monitor monitors the following resources:

Logical Volume Copies

(

/vg/<vgName> /lv/copies/<volumeName>)

This resource is an integer representing the current number of data copies in a logical volume. It is only

valid for mirrored disks conﬁgured with MirrorDisk/UX. The number of copies includes the primary copy

of data plus all mirrors. This resource can be used to determine if one or more of the copies of data is

unavailable.

Possible values are:

0 No complete copies of the data are available. If a volume group or logical volume is inactive, there

will be 0 copies available.

1 One complete copy of the data is available. If the data is unmirrored, then all physical extents are

up. If the data is 2-way mirrored, at least one of the logical extents has a missing or stale physical

extent. If the data is 3-way mirrored, at least one of the logical extents has a missing/stale physical

extent.

2 Two complete copies of the data are available. If the data is 2-way mirrored, all copies of the data

are available. If the data is 3-way mirrored, at least one of the logical extents has a missing/stale

physical extent.

3 All copies of the data are available. This is only possible with three-way mirroring.

Logical Volume Status

(

/vg/<vgName> /lv/status/<volumeName>)

This resource represents the status of a logical volume as reported by LVM. LVM status is based on the

last I/O activity. The following enumerated states can be reported:

UP Active and at least one copy of all data is available

INACTIVE This logical volume is currently inactive

DOWN Active and at least one portion of data is completely unavailable

Logical Volume Summary

(

/vg/<vgName> /lv_summary)
