smp_conf_zone_man_pass - invoke CONFIGURE ZONE MANAGER PASSWORD function
] [ --hex
] [ --new-pass=NP
] [ --sa=SAS_ADDR
Sends a SAS Serial Management Protocol (SMP) CONFIGURE ZONE MANAGER PASSWORD
function request to an SMP target. The SMP target is identified by the
and the --sa=SAS_ADDR
. Depending on the interface,
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
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
- -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
- -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
- -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
- -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 .
