smp_zone_lock: invoke ZONE LOCK SMP function
NAMEsmp_zone_lock - invoke ZONE LOCK SMP function
SYNOPSISsmp_zone_lock [--expected=EX] [--fpass=FP] [--help] [--hex] [--inactivity=TL] [--interface=PARAMS] [--password=PA] [--raw] [--sa=SAS_ADDR] [--verbose] [--version] SMP_DEVICE[,N]
Sends a SAS Serial Management Protocol (SMP) ZONE LOCK 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.
OPTIONSMandatory 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 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.
- -h, --help
- output the usage message then exit.
- -H, --hex
- output the response (less the CRC field) in hexadecimal.
- -i, --inactivity=TL
- sets the zone lock inactivity time limit to TL which has units of 100 milliseconds. The default value is 0 which implies no time limit.
- -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.
- -P, --password=PA
- where PA is the 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.
- -v, --verbose
- increase the verbosity of the output. Can be used multiple times.
- -V, --version
- print the version string and then exit.
CONFORMING TOThe SMP ZONE LOCK function was introduced in SAS-2 .
