SMP_DEVICE[,N]
Sends a SAS Serial Management Protocol (SMP) CONFIGURE ZONE
MANAGER PASSWORD function request to an SMP target. The SMP target is
identified by the SMP_DEVICE and the --sa=SAS_ADDR. Depending
on the interface, the SAS_ADDR may be deduced from the
SMP_DEVICE. The mpt interface uses SMP_DEVICE to identify a
HBA (an SMP initiator) and needs the additional ,N to differentiate
between HBAs if there are multiple present.
Mandatory arguments to long options are mandatory for short
options as well.
- -E,
--expected=EX
- set the 'expected expander change count' field in the SMP request. The
value EX is from 0 to 65535 inclusive with 0 being the default
value. When EX is greater than zero then if the value doesn't match
the expander change count of the SMP target (i.e. the expander) when the
request arrives then the target ignores the request and sets a function
result of "invalid expander change count" in the response.
- -F,
--fpass=FP
- where FP is the name of a file which contains the existing
password. The password may be in ASCII in which case it is on one line
surrounded by either single quotes are double quotes. Alternatively the
password may be given in ASCII hexadecimal; either as bytes separated by
space, tab, comma or newline, or as longer strings of hexadecimal bytes in
which every 2 digits represents a byte. Empty lines and those starting
with "#" are ignored. A line starting with '-1' causes all
remaining bytes in the password to be filled with 0xff.
- -h, --help
- output the usage message then exit.
- -H, --hex
- output the response (less the CRC field) in hexadecimal.
- -I,
--interface=PARAMS
- interface specific parameters. In this case "interface" refers
to the path through the operating system to the SMP initiator. See the
smp_utils man page for more information.
- -N,
--new-fpass=NF
- where NF is the name of a file which contains the new password. The
format of this file is the same as the file given in
--fpass=FP.
- -n,
--new-pass=NP
- where NP is the new zone manager password which may be up to 32
bytes long. This option cannot be give together with the
--new-fpass=NF option. The default password is 32 NULLs (zero
bytes) and PA is padded with NULLs to the right (to make it 32
bytes long in the request).
- -P,
--password=PA
- where PA is the existing zone manager password which may be up to
32 bytes long. This option cannot be give together with the
--fpass=FP option. The default password is 32 NULLs (zero bytes)
and PA is padded with NULLs to the right (to make it 32 bytes long
in the request).
- -r, --raw
- send the response (less the CRC field) to stdout in binary. All error
messages are sent to stderr.
- -s,
--sa=SAS_ADDR
- specifies the SAS address of the SMP target device. The mpt interface
needs this option and it will typically be an expander's SAS address. The
SAS_ADDR is in decimal but most SAS addresses are shown in
hexadecimal. To give a number in hexadecimal either prefix it with '0x' or
put a trailing 'h' on it.
- -S,
--save=SAV
- set the 'save' field in the SMP request. SAV may take these values:
0 for updating the shadow values (default), 1 for updating the saved
values, 2 for updating shadow values and if available the saved values, 3
for updating both saved and shadow values.
- -v, --verbose
- increase the verbosity of the output. Can be used multiple times.
- -V, --version
- print the version string and then exit.
Hexadecimal bytes (or longer hexadecimal strings) should not have
a leading "0x" or trailing "h" decoration.
The "well known" DISABLE password is 32 bytes of 0xff.
The new password can only be DISABLED if physical presence is supported and
asserted.
The SMP CONFIGURE ZONE MANAGER PASSWORD function was introduced in
SAS-2 .
