NAME
smp_conf_zone_man_pass - invoke CONFIGURE ZONE MANAGER PASSWORD func‐
tion
SYNOPSIS
smp_conf_zone_man_pass [--expected=EX] [--fpass=FP] [--help] [--hex]
[--interface=PARAMS] [--new-fpass=NF] [--new-pass=NP] [--password=PA]
[--raw] [--sa=SAS_ADDR] [--save=SAV] [--verbose] [--version]
SMP_DEVICE[,N]
DESCRIPTION
Sends a SAS Management Protocol (SMP) CONFIGURE ZONE MANAGER PASSWORD
function request to a 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 addi‐
tional ,N to differentiate between HBAs if there are multiple present.
OPTIONS
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 pass‐
word. 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 rep‐
resents 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 hexa‐
decimal 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 val‐
ues: 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.
NOTES
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.
CONFORMING TO
The SMP CONFIGURE ZONE MANAGER PASSWORD function was introduced in
SAS-2 .
