smp_ena_dis_zoning - invoke ENABLE DISABLE ZONING SMP function
smp_ena_dis_zoning [--disable] [--ena-dis=ED]
[--expected=EX] [--help] [--hex]
[--interface=PARAMS] [--raw] [--sa=SAS_ADDR]
[--save=SAV] [--verbose] [--version]
SMP_DEVICE[,N]
Sends a SAS Serial Management Protocol (SMP) ENABLE DISABLE ZONING
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.
If neither --disable nor --ena-dis=ED options are
given then enable zoning (i.e. "--ena-dis=1") is assumed.
This function does not change the state of the current zoning
enabled flag (as seen in the REPORT GENERAL response). Such a state change
will occur on a subsequent invocation of the ZONE ACTIVATE function.
Mandatory arguments to long options are mandatory for short
options as well.
- -d, --disable
- set the 'enable disable zoning' field in the SMP request to 2 which will
disable zoning.
- -e,
--ena-dis=ED
- set the 'enable disable zoning' field in the SMP request. ED may
take these values: 0 for no change, 1 for enable zoning (default) and 2
for disable zoning. If this option and the --disable option are
both given then they cannot contradict one another.
- -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.
- -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.
- -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.
The SMP ENABLE DISABLE ZONING function was introduced in SAS-2
.
