SMP_ZONE_UNLOCK(8) SMP_UTILS SMP_ZONE_UNLOCK(8)
NAME
smp_zone_unlock - invoke ZONE UNLOCK SMP function
SYNOPSIS
smp_zone_unlock [--activate] [--expected=EX] [--help] [--hex] [--inter‐
face=PARAMS] [--raw] [--sa=SAS_ADDR] [--verbose] [--version]
SMP_DEVICE[,N]
DESCRIPTION
Sends a SAS Management Protocol (SMP) ZONE UNLOCK 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 this function is successful then a Broadcast (Change) is sent from
either each zone group whose zone permission table entries or zone phy
information has changed; or from zone group 1. Broadcast (Change)
should cause a management application client behind a SMP initiator
port (e.g. a SAS HBA) to start a discover process.
OPTIONS
Mandatory arguments to long options are mandatory for short options as
well.
-a, --activate
sets the ACTIVATE REQUIRED bit in the function request. When it
is set the function call will fail with a function result of NOT
ACTIVATED if the expander has not "processed the activate step".
-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 hexa‐
decimal 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.
