smp_zone_unlock: invoke ZONE UNLOCK SMP function

NAME

smp_zone_unlock - invoke ZONE UNLOCK SMP function

SYNOPSIS

smp_zone_unlock [--activate] [--expected=EX] [--help] [--hex] [--interface=PARAMS] [--raw] [--sa=SAS_ADDR] [--verbose] [--version] SMP_DEVICE[,N]

DESCRIPTION

Sends a SAS Serial Management Protocol (SMP) ZONE UNLOCK 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 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 an 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 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 TO

The SMP ZONE UNLOCK function was introduced in SAS-2 .
