na_sasadmin - Commands for managing Serial Attached SCSI
(SAS) adapters.
sasadmin command argument ...
The sasadmin utility commands manage the SAS adapters and
expanders used by the storage subsystem. These commands
show SAS channels, information about attached expanders or
disk shelves, expander and adapter phy (transceiver)
states and the status of disk drives.
sasadmin
[dev_stats|adapter_state|expander_map|shelf|shelf_short]
[<adapter_name>]
sasadmin expander <adapter_name>[.<shelf_id>]
sasadmin expander_phy_state [<adapter_name>[.<shelf_id>]]
Following is the convention used to name devices in a SAS
domain.
End devices are named using the concatenated form
<adapter_name>.<shelf_id>.<bay_id>, where
adapter_name: An adapter name of the form Xy, where
X is a number and y is a letter (for example, 0c or
0d).
shelf_id: A number between 0 through 99. This number
corresponds to the thumbwheel setting in the
front of the disk shelf or controller (sometimes
referred to as "filer" or "appliance"). If no
thumbwheel is present, 0 is used. In the cases
where the disk shelf ID is either not assigned or
unavailable, the serial number of the disk shelf is
used instead.
bay_id: The physical bay number where the disk
drive is located. Bays are numbered from left to
right, top to bottom, starting with 0. Therefore,
bay 0 is the top left slot of the disk shelf.
Examples device names:
0c.5.19 would be the device in bay number 19 of
disk shelf number 5 attached to the adapter 0c.
0d.449292.19 would be the device in bay number 19
of disk shelf with the serial number 449292
attached to the adapter 0d.
sasadmin dev_stats [<adapter_name>]
The sasadmin dev_stats command displays various statistics
associated with disk drives connected to SAS channels in
the controller. filer> sasadmin dev_stats 0c

The State for adapter channel field displays the adapter
name and its current state, which is one of the following:
-
INITING:
- This state is entered only upon
system boot while internal structures
are being initialized.
-
DOWN:
- The channel is currently not
functional. It could either be a
result of the adapter being
reset, or an adapter port has
gone down.
-
UP:
- The normal operating state, where
the channel is connected and all
phys in the channel are up.
-
UP (degraded):
- The channel is up, but one or
more of the constituent phys are
not connected at the programmed
maximum link rate.
-
OFFLINE (logical):
- This state is entered upon user
request. All devices are invalidated
before entering this state.
This state is not exited until a
user manually requests that the
adapter be brought online again.
-
OFFLINE (physical):
- This state is entered when, after
enabling the adapter, all the
constituent phys fail to come up
because the channel is not connected
to any end device. User
intervention is not required if
the end devices are hot-plugged
into this channel in this state.
-
ZOMBIFIED:
- The entry into this state is only
for a short time (typically 30
seconds) and the adapter is then
automatically returned to the UP
state. While the adapter is in
this state, devices are not
invalidated, they are held in a
temporary state of suspended animation.
The PHY refers to the adapter physical phy number for
which the state is displayed.
The STATE refers to the current state of the phy. Possible
states are Rate unknown (Link up but link speed not
known), Disabled (Phy disabled), Spd neg. fail (Speed
negotiations between the expander and the host bus adapter
[HBA] failed), SATA OOB fail (SATA out-of-band-signaling
[OOB] sequence failed), 1.5 Gb/s (Link up at 1.5 Gb/s),
3.0 Gb/s (Link up at 3.0 Gb/s) and State unknown (Current
state is none of the others).
The Invald DWord Count (invalid dword count) column refers
to the number of invalid dwords seen (outside of the phy
reset sequence) on this phy.
The Disprt Error Count (disparity error count) column
refers to the number of dwords with a running disparity
error seen (outside the phy reset sequence) on this phy.
The Loss Sync Count (loss of dword synchronization) column
refers to the number of times the phy lost dword synchronization
and restarted the link reset sequence of the phy
reset sequence.
The Phy Reset Prob (phy reset problem count) column refers
to the number of times the phy reset sequence failed.
The Phy Change Count column refers to the number of times
the phy link status changed.
The Frames In field refers to a rough count of response
frames and data frames received by the adapter.
The Frames Out field refers to a rough count of command
frames and data frames transmitted by the adapter.
The Command Completed successfully field refers to the
number of commands successfully executed by the adapter.
The Command Completed in error field refers to the number
of commands executed by this adapter that resulted in an
error.

The WWN field refers to the base SAS address of the
expander.
For the definition of the ID field, see "SAS DEVICE NAMING
CONVENTION", above.
The Serial Number refers to the back plane serial number
of the enclosure where the expander is housed.
The Vendor field of the Manufacturer line refers to the
Vendor Identification field reported by the Report Manufacturer
Info SMP command. It is 8 bytes of left-aligned
ASCII data that was assigned by INCITS and is set to
"NETAPP ", with all trailing white spaces filled with
blank characters (20h).
For the definition of the Product field of the Manufacturer
line see the Product field definition under "sasadmin
expander_map", above.
The Rev field of the Manufacturer line refers to the running
firmware version of the expander.
The Level field of the Manufacturer line refers to the SAS
topology level assigned by the first SAS adapter port that
discovered the expander during SAS discovery.
The Slot field refers to the slot where the expander
resides. The top module is termed Slot A and the bottom
module is termed Slot B.
The remaining portion of the output of the command displays
information regarding each phy of the expander. The
format of each line would be as follows:
PHY[<logical phy number>/[Port Number:Phy Number|Bay
ID]/<routing attribute>]:<Phy State>, [[Virtual] <End
device type> <WWN> <Device name>]
The logical phy number field displays the logical phy number
for which information is being displayed.
The Port Number:Phy Number combination field displays
whether this phy is part of a wide port SAS link and the
phy number within the wide port.
For the definition of the Bay ID field, see "SAS DEVICE
NAMING CONVENTION", above.
The routing attribute field display the SAS routing
attribute for the phy. Possible routing attribute types
are S for subtractive routing, T for table routing and D
for direct routing.
For the definition of the Phy State field, see "STATE"
under "sasadmin adapter_state", above.
The End device type field displays the type of end device
attached to this phy. Possible end device types are
"Unknown", "Initiator", "Expander", "SAS Device" and "SATA
Device". The optional attribute Virtual is added if the
end device is a SAS virtual device. For example, the SCSI
Enclosure Services (SES) device in the expander is a virtual
device.
The WWN field refers to the SAS address of the end device
attached to this phy.
The Device name field display the Data ONTAP(R) device
name, if the end device is either a SAS or a SATA disk
drive, which is described in "SAS DEVICE NAMING CONVENTION",
above.
Example output for all commands is included in their
descriptions.
All options for all commands are included in their
descriptions.
sas.adapter.reset:
The Data ONTAP SAS driver is resetting the specified
host adapter. This can occur during normal
error handling or when requested by the user.
sas.device.quiesce:
This indicates that at least one command to the
specified device has not been completed in what
would be the normally expected timeframe. In this
case, the driver stops sending additional commands
to the device until all outstanding commands have
the opportunity to be completed. This condition is
automatically handled by the Data ONTAP(R) SAS
driver.
sas.device.timeout:
All outstanding commands to the specified device
have not been completed within the allotted time.
As part of the standard error handling sequence
managed by the Data ONTAP SAS driver, all commands
to the device are aborted and reissued.
sas.device.resetting:
This indicates that device level error recovery has
escalated to resetting the device. It is usually
seen in association with error conditions such as
device level timeouts or transmission errors. This
event reports the recovery action taken by the Data
ONTAP(R) SAS driver when evaluating associated
device or link related error conditions.
sas.channel.resetting:
This indicates that error recovery has escalated to
resetting all devices on the specified channel. It
is usually seen in association with error conditions
such as device level timeouts or transmission
errors. This event is intended to report the recovery
action taken by the Data ONTAP SAS driver when
evaluating associated device or link related error
conditions.
sas.adapter.bad:
The SAS adapter failed to initialize.
sas.adapter.firmware.fault:
A firmware fault was detected on the SAS adapter
and it is being reset to recover.
sas.adapter.not.ready:
The SAS adapter did not become ready after being
reset.
sas.adapter.error:
The SAS adapter driver encountered an error with
the adapter. The adapter is being reset to
recover.
sas.adapter.unexpected.status:
The SAS adapter returned an unexpected status and
is being reset to recover.
"Not a SAS adapter."
"No such adapter adapter_name."
"This operation not allowed on channel chan_name."
"Device device_name is not valid or does not
exist."
"Failed."
No known bugs exist at this time.
