smp_conf_zone_phy_info - invoke CONFIGURE ZONE PHY INFORMATION function
] [ --interface=PARAMS
Sends a SAS Serial Management Protocol (SMP) CONFIGURE ZONE PHY INFORMATION
function request to an SMP target. The SMP target is identified by the
and the --sa=SAS_ADDR
. Depending on the interface,
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
Each zone phy configuration descriptor is 4 bytes long. The first byte is a
(expander) phy identifier. The second byte has 3 modifiable bits: bit 5 is
"inside ZPSDS persistent"; bit 4 is "requested inside
ZPSDS"; and bit 2 is "zone group persistent". The other bits in
the second byte are reserved and should be 0. The third byte is reserved and
should be 0. The fourth byte is the zone group.
Mandatory arguments to long options are mandatory for short options as well.
- -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
- -h, --help
- output the usage message then exit.
- -H, --hex
- output the response (less the CRC field) in
- -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.
- -p, --pconf=FN
- FN is a file containing zone phy configuration
descriptors in ASCII hexadecimal; either as bytes separated by space, tab,
comma or newline, or as longer strings of hexadecimal bytes in which every
2 digits represents a byte. Empty lines and those starting with
"#" are ignored. Since each zone phy configuration descriptor is
4 bytes long, the number of bytes in FN is expected to be a
multiple of 4.
- -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
- -V, --version
- print the version string and then exit.
The expander phys that make up a wide port (2 or more attached to phys with the
same SAS address) must be set to the same zone phy configuration settings
(other than the phy id).
Zone phy information can be read back from an expander and placed in a file with
the smp_discover_list utility's --zpi=FN
option. The format of that
file should be suitable for this utility's --pconf=FN
The SMP CONFIGURE ZONE PHY INFORMATION function was introduced in SAS-2 .
