.TH SMP_CONF_ZONE_PHY_INFO "8" "May 2011" "smp_utils\-0.96" SMP_UTILS .SH NAME smp_conf_zone_phy_info \- invoke CONFIGURE ZONE PHY INFORMATION function .SH SYNOPSIS .B smp_conf_zone_phy_info [\fI\-\-expected=EX\fR] [\fI\-\-help\fR] [\fI\-\-hex\fR] [\fI\-\-interface=PARAMS\fR] \fI\-\-pconf=FN\fR [\fI\-\-raw\fR] [\fI\-\-sa=SAS_ADDR\fR] [\fI\-\-save=SAV\fR] [\fI\-\-verbose\fR] [\fI\-\-version\fR] \fISMP_DEVICE[,N]\fR .SH DESCRIPTION .\" Add any additional description here .PP Sends a SAS Serial Management Protocol (SMP) CONFIGURE ZONE PHY INFORMATION function request to an SMP target. The SMP target is identified by the \fISMP_DEVICE\fR and the \fI\-\-sa=SAS_ADDR\fR. Depending on the interface, the \fISAS_ADDR\fR may be deduced from the \fISMP_DEVICE\fR. The mpt interface uses \fISMP_DEVICE\fR to identify a HBA (an SMP initiator) and needs the additional \fI,N\fR to differentiate between HBAs if there are multiple present. .PP 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. .SH OPTIONS Mandatory arguments to long options are mandatory for short options as well. .TP \fB\-E\fR, \fB\-\-expected\fR=\fIEX\fR set the 'expected expander change count' field in the SMP request. The value \fIEX\fR is from 0 to 65535 inclusive with 0 being the default value. When \fIEX\fR 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. .TP \fB\-h\fR, \fB\-\-help\fR output the usage message then exit. .TP \fB\-H\fR, \fB\-\-hex\fR output the response (less the CRC field) in hexadecimal. .TP \fB\-I\fR, \fB\-\-interface\fR=\fIPARAMS\fR 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. .TP \fB\-p\fR, \fB\-\-pconf\fR=\fIFN\fR \fIFN\fR 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 \fIFN\fR is expected to be a multiple of 4. .TP \fB\-r\fR, \fB\-\-raw\fR send the response (less the CRC field) to stdout in binary. All error messages are sent to stderr. .TP \fB\-s\fR, \fB\-\-sa\fR=\fISAS_ADDR\fR 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 \fISAS_ADDR\fR 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. .TP \fB\-S\fR, \fB\-\-save\fR=\fISAV\fR set the 'save' field in the SMP request. \fISAV\fR 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. .TP \fB\-v\fR, \fB\-\-verbose\fR increase the verbosity of the output. Can be used multiple times. .TP \fB\-V\fR, \fB\-\-version\fR print the version string and then exit. .SH NOTES 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). .PP Zone phy information can be read back from an expander and placed in a file with the smp_discover_list utility's \fI\-\-zpi=FN\fR option. The format of that file should be suitable for this utility's \fI\-\-pconf=FN\fR option. .SH CONFORMING TO The SMP CONFIGURE ZONE PHY INFORMATION function was introduced in SAS\-2 . .SH AUTHORS Written by Douglas Gilbert. .SH "REPORTING BUGS" Report bugs to . .SH COPYRIGHT Copyright \(co 2011 Douglas Gilbert .br This software is distributed under a FreeBSD license.
