.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility can be used to display or modify various parameters on LSI
|
|
MegaRAID SAS RAID controllers.
|
|
Each invocation of
|
|
.Nm
|
|
consists of zero or more global options followed by a command.
|
|
Commands may support additional optional or required arguments after the
|
|
command.
|
|
.Pp
|
|
Currently one global option is supported:
|
|
.Bl -tag -width indent
|
|
.It Fl u Ar unit
|
|
.Ar unit
|
|
specifies the unit of the controller to work with.
|
|
If no unit is specified,
|
|
then unit 0 is used.
|
|
.El
|
|
.Pp
|
|
Various commands accept either or both of the two options:
|
|
.Bl -tag -width indent
|
|
.It Fl d
|
|
Print numeric device IDs as drive identifier.
|
|
This is the default.
|
|
Useful in combination with
|
|
.Fl e
|
|
to print both, numeric device IDs and enclosure:slot information.
|
|
.It Fl e
|
|
Print drive identifiers in enclosure:slot form.
|
|
See next paragraph on format details in context of input rather than
|
|
output.
|
|
.El
|
|
.Pp
|
|
Drives may be specified in two forms.
|
|
First,
|
|
a drive may be identified by its device ID.
|
|
The device ID for configured drives can be found in
|
|
.Cm show config .
|
|
Second,
|
|
a drive may be identified by its location as
|
|
.Sm off
|
|
.Op E Ar xx Ns \&:
|
|
.Li S Ns Ar yy
|
|
.Sm on
|
|
where
|
|
.Ar xx
|
|
is the enclosure
|
|
and
|
|
.Ar yy
|
|
is the slot for each drive as displayed in
|
|
.Cm show drives .
|
|
.Pp
|
|
Volumes may be specified in two forms.
|
|
First,
|
|
a volume may be identified by its target ID.
|
|
Second,
|
|
on the volume may be specified by the corresponding
|
|
.Em mfidX
|
|
device,
|
|
such as
|
|
.Em mfid0 .
|
|
.Pp
|
|
The
|
|
.Nm
|
|
utility supports several different groups of commands.
|
|
The first group of commands provide information about the controller,
|
|
the volumes it manages, and the drives it controls.
|
|
The second group of commands are used to manage the physical drives
|
|
attached to the controller.
|
|
The third group of commands are used to manage the logical volumes
|
|
managed by the controller.
|
|
The fourth group of commands are used to manage the drive configuration for
|
|
the controller.
|
|
The fifth group of commands are used to manage controller-wide operations.
|
|
.Pp
|
|
The informational commands include:
|
|
.Bl -tag -width indent
|
|
.It Cm version
|
|
Displays the version of
|
|
.Nm .
|
|
.It Cm show adapter
|
|
Displays information about the RAID controller such as the model number.
|
|
.It Cm show battery
|
|
Displays information about the battery from the battery backup unit.
|
|
.It Cm show config
|
|
Displays the volume and drive configuration for the controller.
|
|
Each array is listed along with the physical drives the array is built from.
|
|
Each volume is listed along with the arrays that the volume spans.
|
|
If any hot spare drives are configured, then they are listed as well.
|
|
.It Cm show drives
|
|
Lists all of the physical drives attached to the controller.
|
|
.It Xo Cm show events
|
|
.Op Fl c Ar class
|
|
.Op Fl l Ar locale
|
|
.Op Fl n Ar count
|
|
.Op Fl v
|
|
.Op Ar start Op Ar stop
|
|
.Xc
|
|
Display entries from the controller's event log.
|
|
The controller maintains a circular buffer of events.
|
|
Each event is tagged with a class and locale.
|
|
.Pp
|
|
The
|
|
.Ar class
|
|
parameter limits the output to entries at the specified class or higher.
|
|
The default class is
|
|
.Dq warn .
|
|
The available classes from lowest priority to highest are:
|
|
.Bl -tag -width indent
|
|
.It Cm debug
|
|
Debug messages.
|
|
.It Cm progress
|
|
Periodic progress updates for long-running operations such as background
|
|
initializations, array rebuilds, or patrol reads.
|
|
.It Cm info
|
|
Informational messages such as drive insertions and volume creations.
|
|
.It Cm warn
|
|
Indicates that some component may be close to failing.
|
|
.It Cm crit
|
|
A component has failed, but no data is lost.
|
|
For example, a volume becoming degraded due to a drive failure.
|
|
.It Cm fatal
|
|
A component has failed resulting in data loss.
|
|
.It Cm dead
|
|
The controller itself has died.
|
|
.El
|
|
.Pp
|
|
The
|
|
.Ar locale
|
|
parameter limits the output to entries for the specified part of the controller.
|
|
The default locale is
|
|
.Dq all .
|
|
The available locales are
|
|
.Dq volume ,
|
|
.Dq drive ,
|
|
.Dq enclosure ,
|
|
.Dq battery ,
|
|
.Dq sas ,
|
|
.Dq controller ,
|
|
.Dq config ,
|
|
.Dq cluster ,
|
|
and
|
|
.Dq all .
|
|
.Pp
|
|
The
|
|
.Ar count
|
|
parameter is a debugging aid that specifies the number of events to fetch from
|
|
the controller for each low-level request.
|
|
The default is 15 events.
|
|
.Pp
|
|
By default, matching event log entries from the previous shutdown up to the
|
|
present are displayed. This range can be adjusted via the
|
|
.Ar start
|
|
and
|
|
.Ar stop
|
|
parameters.
|
|
Each of these parameters can either be specified as a log entry number or as
|
|
one of the following aliases:
|
|
.Bl -tag -width indent
|
|
.It Cm newest
|
|
The newest entry in the event log.
|
|

.It Cm rebuild Ar drive
|
|
Mark a failed
|
|
.Ar drive

|
is marked as a rebuild drive.
|
|
.It Cm syspd Ar drive
|
|
Present the drive to the host operating system as a disk SYSPD block device in

.Bl -tag -width indent
|
|
.It Cm cache Ar volume Op Ar setting Oo Ar value Oc Op ...
|
|
If no
|
|
.Ar setting
|
|
arguments are supplied, then the current cache policy for
|
|
.Ar volume
|
|
is displayed;
|
|
otherwise,
|
|
the cache policy for
|
|
.Ar volume
|
|
is modified.
|
|
One or more
|
|
.Ar setting
|
|
arguments may be given.
|
|
Some settings take an additional
|

In general this setting should be left disabled to avoid data loss when
|
|
the system loses power.

.Pp
|
|
In general this setting should be left disabled to avoid data loss when the
|
|
physical drives lose power.

list.
|
|
.El
|
|
.Pp
|
|
.Sy Note:
|
|
Not all volume types are supported by all controllers.
|
|
.Pp
|
|
If the
|
|
.Fl v
|
|
flag is specified after
|
|
.Ar type ,
|
|
then more verbose output will be enabled.
|
|
Currently this just provides notification as drives are added to arrays and
|
|
arrays to volumes when building the configuration.
|
|
.Pp
|
|
The
|
|
.Fl s
|
|
.Ar stripe_size
|
|
parameter allows the stripe size of the array to be set.
|
|
By default a stripe size of 64K is used.

Valid values are 512 through 1M, though the MFI firmware may reject some
|
|
values.

|
|
.Ar Drive
|
|
must be in the unconfigured good state.
|
|
If
|
|
.Ar volume
|
|
is specified,
|
|
then the hot spare will be dedicated to arrays backing that volume.
|
|
Otherwise,
|
|
.Ar drive
|
|
will be used as a global hot spare backing all arrays for this controller.
|
|
Note that
|
|
.Ar drive
|
|
must be as large as the smallest drive in all of the arrays it is going to
|
|
back.
