SMP_ENA_DIS_ZONING(8) SMP_UTILS SMP_ENA_DIS_ZONING(8)
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.
