-spinq
Inquire spin status
No
Set n to 1 for one iteration. This is normally sufficient. The
official Department of Defense specification states that you
must use 3 full passes for compliance to their spec.
-
spindow
n
Check to see if disk has
"data" on it
Possibly
Never spin a disk down a mounted disk with live data, unless
it is your intention to simulate a drive failure. The software
does not test to see if the disk is used in any way.
-spinup
Spin disk up and wait for
confirmation
No
-
spindow
ni
Spin disk down (immediate)
Possibly
Same warning as stated above about spinning mounted
disks down
-
spinupi
Spin disk up (immediate)
No
The immediate bit, as defined by ANSI, basically means to
return an OK status immediately after the command has
been sent, rather than pausing the program while waiting for
disk to start up.
Miscellaneous Programming
Flag
Description
Destructive
Notes
-capacity
nBlocks
Changes drive capacity
(resizes disk)
No
Not destructive as it is reversible, but it can hide usable
storage
-
capacityb
s
Blocksize
Changes block size
Yes
All data will be lost and drive must be reformatted. Block
sizes are normally 512, but some RAID systems, such as
NetApp and EMC use 520 block sizes
-confirm
Automatic affirmative
response
No
Responds "Y" to any are-you-sure type messages that are
typically associated with destructive commands such as
running a destructive write data integrity test.
-flash
Flashes device firmware
Possibly
If you use wrong firmware image then device may have to go
back to factory to get recovered.
-format
Low level format
Yes
All data will be lost (unless the data was all zeros)
-p
Disable S.M.A.R.T.
No
S.M.A.R.T. setting will revert to previous value after power
cycle
-pp
Disable S.M.A.R.T. ,
permanently
No
This turns off S.M.A.R.T. so it stays off after power cycle.
You must enable it with the mode page editor function.
-rb
Reassign block
Possibly
-rc
Corrupt block
Yes
Destroys contents of this block by corrupting ECC data. Use
this to test to see that a corrupted block is handled properly
by your RAID engine or path/data fail over redundancy
hardware or software.
-wsbyte
Write SAME
Yes
Sends same byte to every block on the random-access
device
-
wsbytecon
firm
Write SAME
Yes
Same as -wsbyte, but no are-you-sure
-16
16-byte CDB
Possibly
This forces program to use the 16-byte SCSI command
instead of the 10-byte SCSI commands for the -ws and -
scrub family functions. Your host O/S and drivers, and
target devices must all support 16-byte commands.
-12
12-byte CDB
Possibly
This forces using the READ(12) and WRITE(12) commands
for the -scrub family commands. Like the 16-byte commands,
it is not necessarily going to be supported by your O/S or
your storage hardware.
