DISKINFO(1m)DISKINFO(1m)NAMEdiskinfo-- Provide disk device inventory and status
SYNOPSISdiskinfo [-Hp] [{-c|-P}]
DESCRIPTION
The diskinfo tool provides information about the disk devices in the
system. Because it interacts with the kernel´s device management sub‐
system, this tool can be used only from the global zone. If run in any
other zone, its output will be incomplete and unreliable.
There are three main modes. The default mode, when neither the -c nor
-P option is specified, provides a basic inventory of the disk devices
in the system. Each line describes a single device and contains the
device´s attachment bus or fabric type, the base name of the device in
the /dev/dsk directory, the disk´s vendor and product identification
strings, the size (storage capacity) of the device, whether the device
is removable, and whether it is solid-state.
The -P option selects physical mode. In this mode, each line of output
likewise describes one disk device; however, the fields provided indi‐
cate the base name of the device in the /dev/dsk directory, the disk´s
vendor and product identification strings, the serial number of the
device, whether the device is faulty as diagnosed by fmd(1M), whether
the locate or identification indicator is on for the device (if one is
present), and the chassis and bay number containing the disk if known.
The -c option selects compact mode. This mode provides all of the
information provided by both the default mode and physical mode in a
compact format.
See OUTPUT FIELDS below for a detailed description of each column.
OPTIONS-c
Select compact mode output. At most one of -c and -P may be present on
the command line.
-H
Do not print a header. This provides output suitable for passing into
text processing tools.
-P
Select physical mode output. At most one of -P and -c may be present
on the command line.
-p
Parseable output. When -p is selected, the size (storage capacity) is
output in bytes instead of in human-readable units, and the device´s
location (if known) is provided as a comma-separated chassis and bay
number instead of a human-readable location. This option may be used
in any output mode and is intended for use by scripts or other robotic
tooling.
OUTPUT FIELDS
"DISK"
The base name of the device node within the /dev/dsk directory. The
names of partitions and/or slices, if any, are derived from this name
as described by prtvtoc(1M).
This field is available in all output modes.
"FLRS"
A condensed field incorporating the same information as the "FLT",
"LOC", "RMV", and "SSD" fields. Each field is condensed to a single
character. If the field is true, the first letter of the field name
will appear in its position in the string; otherwise, the "-" character
will appear instead.
This field is available only in compact output mode.
"FLT"
A boolean field indicating whether the device is faulty; specifically,
whether the fault indicator (if one is present) is active.
This field is available only in physical output mode.
"LOC"
A boolean field indicating whether the locate or identify indicator, if
any, associated with the device´s bay, is active.
This field is available only in physical output mode.
"LOCATION"
The physical chassis and bay name (or chassis and bay numbers, if -p is
given) in which the device is located. The chassis number is identi‐
fied in human-readable output within [ square brackets ]; chassis 0 is
the host chassis itself. The bay name, if any, is provided by the
enclosure, typically via a SCSI Enclosure Services processor.
This field is available in compact and physical output modes.
"PID"
The product identification string reported by the device.
This field is available in all output modes.
"RMV"
A boolean field indicating whether the device is removable. USB stor‐
age devices, most optical drives and changers, and certain other
devices that report themselves as removable will be identified as such.
SmartOS will not normally consider removable-media storage devices to
be candidates for its persistent storage pool.
This field is available only in default output mode.
"SERIAL"
The serial number of the device. The entire serial number is reported
if the device and its drivers provide it.
This field is available in compact and physical output modes.
"SIZE"
The device´s storage capacity. If the -p option is given, this is
reported in bytes; otherwise, it is reported in a human-readable format
with units specified. All units are based on powers of 2 and are
expressed in SI standard notation.
This field is available in compact and default output modes.
"SSD"
A boolean field indicating whether the device is solid-state. In order
to be correctly identified as solid-state, the device must identify
itself as such in the manner provided for by the T10 SPC-4 specifica‐
tion or another mechanism understood by sd(7D). Not all devices do so.
This field is available only in default output mode.
"TYPE"
The transport (fabric or bus) type by which the storage device is
attached to the host, if known. Typical transports include SCSI and
USB.
This field is available in compact and default output modes.
"VID"
The vendor identification string reported by the device.
This field is available in all output modes.
