NAME¶
smp_ena_dis_zoning - invoke ENABLE DISABLE ZONING SMP function
SYNOPSIS¶
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]
DESCRIPTION¶
Sends a SAS Management Protocol (SMP) ENABLE DISABLE ZONING 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 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.
OPTIONS¶
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 .
