Utility Options ===============

--echoCommandLine

Echo the command line entered into the utility on the screen.

--enableLegacyUSBPassthrough

Only use this option on old USB or IEEE1394 (Firewire) products that do not otherwise work with the tool. This option will enable a trial and error method that attempts sending various ATA Identify commands through vendor specific means. Because of this, certain products that may respond in unintended ways since they may interpret these commands differently than the bridge chip the command was designed for.

--force

Use the --force option to attempt to override and force a specific operation on a drive in case it is returning "Not supported" messages. This can be used to override some checks for command or feature support. Be aware that sending unsupported commands may result in command failures, and in some circumstances, it may also cause indeterminate behavior of a device. Do not use this command unless you are certain that a device supports the command or feature you are attempting to use. This option is not guaranteed to make things work or fix issues. This option is not available to override every support check or other incompatibility check in the software.

--forceATA

Using this option will force the current drive to be treated as a ATA drive. Only ATA commands will be used to talk to the drive.

--forceATADMA

(SATA Only)

Using this option will force the tool to issue SAT commands to ATA device using the protocol set to DMA whenever possible (on DMA commands). This option can be combined with --forceATA

--forceATAPIO

(SATA Only)

Using this option will force the tool to issue PIO commands to ATA device when possible. This option can be combined with --forceATA

--forceATAUDMA

(SATA Only)

Using this option will force the tool to issue SAT commands to ATA device using the protocol set to UDMA whenever possible (on DMA commands). This option can be combined with --forceATA

--forceSCSI

Using this option will force the current drive to be treated as a SCSI drive. Only SCSI commands will be used to talk to the drive.

-h, --help

Show utility options and example usage (this output you see now) Please report bugs/suggestions to seaboard@seagate.com. Include the output of --version information in the email.

--license

Display the Seagate End User License Agreement (EULA).

--modelMatch [model Number]

Use this option to run on all drives matching the provided model number. This option will provide a closest match although an exact match is preferred. Ex: ST500 will match ST500LM0001

--noBanner

Use this option to suppress the text banner that displays each time openSeaChest is run.

--onlyFW [firmware revision]

Use this option to run on all drives matching the provided firmware revision. This option will only do an exact match.

--onlySeagate

Use this option to match only Seagate drives for the options provided

-q, --quiet

Run openSeaChest_Format in quiet mode. This is the same as -v 0 or --verbose 0

-v [0-4], --verbose [0 | 1 | 2 | 3 | 4]

Show verbose information. Verbosity levels are: 0 - quiet 1 - default 2 - command descriptions 3 - command descriptions and values 4 - command descriptions, values, and data buffers Example: -v 3 or --verbose 3

-V, --version

Show openSeaChest_Format version and copyright information & exit

Utility Arguments =================

-d, --device [deviceHandle | all]

Use this option with most commands to specify the device handle on which to perform an operation. Example: /dev/sg<#> To run across all devices detected in the system, use the "all" argument instead of a device handle. Example: -d all NOTE: The "all" argument is handled by running the

specified options on each drive detected in the

OS sequentially. For parallel operations, please use a script opening a separate instance for each device handle.

--displayLBA [LBA]

This option will read and display the contents of the specified LBA to the screen. The display format is hexadecimal with an ASCII translation on the side (when available).

-F, --scanFlags [option list]

Use this option to control the output from scan with the options listed below. Multiple options can be combined.

ata - show only ATA (SATA) devices

usb - show only USB devices scsi - show only SCSI (SAS) devices nvme - show only NVMe devices interfaceATA - show devices on an ATA interface interfaceUSB - show devices on a USB interface interfaceSCSI - show devices on a SCSI or SAS interface interfaceNVME = show devices on an NVMe interface sd - show sd device handles sgtosd - show the sd and sg device handle mapping

-i, --deviceInfo

Show information and features for the storage device

--llInfo

Dump low-level information about the device to assist with debugging.

--poll

Use this option to cause another operation to poll for progress until it has completed. This argument does not return to the command prompt and prints ongoing completion percentages (%)

the final test result.

Full drive procedures will take a

very long time.

Used with --sanitize, or --writeSame (SATA).

--progress [format | nvmformat | depop | repop]

Get the progress for a test that was started quietly without the polling option (default). You must specify a test you wish to get progress from. Ex: "--progress dst" or "--progress sanitize" The progress counts up from 0% to 100%.

-s, --scan

Scan the system and list all storage devices with logical /dev/sg<#> assignments. Shows model, serial and firmware numbers. If your device is not listed on a scan immediately after booting, then wait 10 seconds and run it again.

-S, --Scan

This option is the same as --scan or -s, however it will also perform a low level rescan to pick up other devices. This low level rescan may wake devices from low power states and may cause the OS to re-enumerate them. Use this option when a device is plugged in and not discovered in a normal scan. NOTE: A low-level rescan may not be available on all interfaces or all OSs. The low-level rescan is not guaranteed to find additional devices in the system when the device is unable to come to a ready state.

--SATInfo

Displays SATA device information on any interface using both SCSI Inquiry / VPD / Log reported data (translated according to SAT) and the ATA Identify / Log reported data.

--testUnitReady

Issues a SCSI Test Unit Ready command and displays the status. If the drive is not ready, the sense key, asc, ascq, and fru will be displayed and a human readable translation from the SPC spec will be displayed if one is available.

--fastDiscovery

Use this option

to issue a fast scan on the specified drive.

--depopulateMaxLBA [requested MaxLBA]

Use this option to specify a new maximum LBA when removing (depopulating) a physical storage element. This is optional. If this is not specified, the device will determine the new maximum LBA. NOTE: If you specify a maximum LBA the device does not support, it will not start the depopulation.

--showPhysicalElementStatus

Use this option to see the status/health of the storage elements inside a drive. Use the element # shown with the --removePhysicalElement option to remove that storage element from use. This option can also be used to see if a depopulation is still in progress or if it has completed.

--showSupportedFormats

This option will show the supported formats of a device. These can be used to change the sector size or used with a format operation. On SAS, this is the supported block lengths and protection types VPD page. (SBC4 and later) On SATA, this is the sector configuration log. (ACS4 and later) If the device does not report supported sector sizes, please consult your product manual.

WARNING: Customer unique firmware may have specific requirements that

restrict sector sizes on some products. It may not be possible to format/ fast format to common sizes like 4K or 512B due to these customer requirements.

SAS Only: ========= --showFormatStatusLog (SAS Only)

Use this option to view the SCSI format status log. Note: This log is only valid after a successful format unit operation.

Data Destructive Commands =========================

--pattern [repeat:asciinospaces | random | increment:startValue | file:filename]

Use this option with overwrite, sanitize, and format unit operations to write a specific pattern to a range of LBAs or the whole drive.

* repeat - without spaces, enter an ASCII text string or a hexadecimal string terminated by a lower case "h". This pattern will be repeated until it fills the logical size of the LBA. i.e. helloword or FFFFFFFFh Note: A hexadecimal pattern will be interpreted as a 32bit unsigned integer. 4 hex bytes (8 characters) must be given for a hex value to be used. Ex: 1F037AC8h or 0000FFFFh * random - the entire logical sector size will be filled with random bytes.This pattern will be written to all LBAs in the desired range. * increment - enter the starting numerical value. Starting with this value, each byte will be written with 1 + previous value. * file - user supplied file name to use for a pattern. The file will be truncated or padded with zeros to the logical sector size Note 1: Each file will be interpreted as a binary file. Note 2: A path must also be provided if the file is not in the

local directory.

Note 3: Sanitize Overwrite on SATA only supports a 32bit pattern.

The file option will get truncated to a 32bit pattern for SATA products.

--removePhysicalElement [element #]

Use this option to remove a storage element from use on a drive. When this is done, the drive will erase all user data and lower the capacity to a new point where the drive is still usable without the provided element #. Use the --showPhysicalElementStatus option to see the status of the depopulation operation.

?[49m?[38;5;9m There is an additional risk when performing a remove physical element as it low-level formats

the drive and may make the drive inoperable if it is reset at any time while it is formatting.

?[0m WARNING: Removing a physical element affect all LUNs/namespaces for devices

with multiple logical units or namespaces.

--repopulateElements

Use this option to repopulate any physical storage elements that have been removed from use. A full disk overwrite is necessary before the drive is usable.

?[49m?[38;5;9m There is an additional risk when performing a repopulate as it low-level formats

the drive and may make the drive inoperable if it is reset at any time while it is formatting.

?[0m WARNING: Removing a physical element affect all LUNs/namespaces for devices

with multiple logical units or namespaces.

--setSectorSize [new sector size]

Changing sector sizes is intended for supported Seagate products used in some hardware RAID configurations. Please consult your hardware RAID documentation for information about compatibility and using 4K native sectors before using this option! Software RAID or individual/JBOD drive solutions will see no benefit as modern file systems and modern operating systems are already 4K aware even on 512 emulation drives. Modern operating systems already align file systems to 4K boundaries required by these drives for optimal performance. Performing a sector size change is data destructive and has a risk that the adapter, driver, or operating system may not know how to communicate with the device once this has completed.

?[49m?[38;5;9m There is an additional risk when performing a low-level format/fast format that may

make the drive inoperable if it is reset at any time while it is formatting.

?[0m For SATA Drives, the set sector configuration command must be supported.

On SAS Drives, fast format must be supported to make these changes.

Use the --showSupportedFormats option to see the sector sizes the drive reports supporting. If this option doesn't list anything, please consult your product manual. This option should be used to quickly change between 5xxe and 4xxx sector sizes. Using this option to change from 512 to 520 or similar is not recommended at this time due to limited drive support

?[49m?[38;5;11m WARNING: Any interruption to the device while it is formatting may render the

drive inoperable! Use this at your own risk!

WARNING: Set sector size may affect all LUNs/namespaces for devices

with multiple logical units or namespaces.

WARNING (SATA): Do not interrupt this operation once it has started or

it may cause the drive to become unusable. Stop all possible background activity that would attempt to communicate with the device while this operation is in progress

WARNING: It is not recommended to do this on USB as not

all USB adapters can handle a 4k sector size.

WARNING: Disable any out-of-band management systems/services/daemons

before using this option. Interruptions can be caused by these and may prevent completion of a sector size change.

WARNING: It is recommended that this operation is done from a bootable environment

(Live USB) to reduce the risk of OS background activities running and triggering a device reset while reformating the drive.

?[0m

SAS Only: ========= --disableCertification

Use this option to disable the certification operation when performing a format unit operation.

--disablePrimaryList

Use this option to disable using the primary defect list when performing a format unit operation.

--discardGList

Use this option to discard the existing grown defect list when performing a format unit operation. (set complete list bit)

--disableImmediateResponse

Use this option to disable the immediate response bit in a format unit operation. Note: This mode may take a long time to complete.

--formatMaxLBA [ new max LBA ]

Use this option to specify a new Max LBA for a drive during a format unit operation. This may speed up a format unit if formatting to test something, or also desiring to reduce a drive's capacity while formatting. NOTE: Not all devices support reducing capacity during a format. Some may ignore this parameter and format the full medium anyways. This is not guaranteed to stick or reduce formatting time.

--protectionIntervalExponent [ exponent value ]

Use this option to specify the protection interval exponent for protection types 2 & 3. This option is ignored for all other protection types.

--protectionType [ 0 | 1 | 2 | 3 ]

Use this option to specify the protection type to format the medium with. Note: Not all devices support protection types.

--fastFormat [fast format mode] (SAS Only) (SBC4 required)

Use this option with the --formatUnit option to run a fast format. Changing sector sizes is intended for supported Seagate products used in some hardware RAID configurations. Please consult your hardware RAID documentation for information about compatibility and using 4K native sectors before using this option! Software RAID or individual/JBOD drive solutions will see no benefit as modern file systems and modern operating systems are already 4K aware even on 512 emulation drives. Modern operating systems already align file systems to 4K boundaries required by these drives for optimal performance. Performing a sector size change is data destructive and has a risk that the adapter, driver, or operating system may not know how to communicate with the device once this has completed.

?[49m?[38;5;9m There is an additional risk when performing a low-level fast format that may

make the drive inoperable if it is reset at any time while it is formatting.
