SMP_REP_PHY_SATA(8)

💖 smp_rep_phy_sata(8) 💖

okay bestie, we're in the SMP_UTILS corner of the manual, and today's main character is smp_rep_phy_sata — the little tool that goes and pokes a REPORT PHY SATA function at an SMP target. no cap. 🦋

✨ SYNOPSIS ✨

smp_rep_phy_sata [--affiliation=AC] [--help] [--hex]
[--interface=PARAMS] [--phy=ID] [--raw] [--sa=SAS_ADDR] [--verbose]
[--version] [--zero] SMP_DEVICE[,N]

🌸 DESCRIPTION 🌸

So basically: this sends a SAS Serial Management Protocol (SMP) REPORT PHY SATA request function to an SMP target. 💅

The SMP target is identified by the SMP_DEVICE and the SAS_ADDR. Depending on the interface, the SAS_ADDR may be deduced from the SMP_DEVICE — so sometimes you don't even gotta say it, it just knows. iykyk.

The mpt interface uses SMP_DEVICE to identify an HBA (an SMP initiator) and needs the additional ,N to differentiate between HBAs if there are multiple present. like, girl, pick a lane. 😭

🎀 the flags, bestie 🎀

• -a, --affiliation=AC — where AC is the affiliation context relative identifier that is placed in request (new in sas2r08). Defaults to 0.
• -h, --help — output the usage message then exit. the classic.
• -H, --hex — output the response (less the CRC field) in hexadecimal. hex girl era ✨
• -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, --phy=ID — phy identifier. ID is a value between 0 and 254. Default is 0.
• -r, --raw — send the response (less the CRC field) to stdout in binary. All error messages are sent to stderr. clean split, love that for us.
• -s, --sa=SAS_ADDR — specifies the SAS address of the SMP target device. Typically this is an expander. This option may not be needed if the SMP_DEVICE has the target's SAS address within it. 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. stack it like accessories. 👑
• -V, --version — print the version string and then exit.
• -z, --zero — zero the Allocated Response Length field in the request. This option also zeros the Request Length field in the request. This is required for strict SAS-1.1 compliance. However this option should not be given in SAS-2 and later; if it is given an abridged response may result.

🚨 real talk: that -z thing is a SAS-1.1-compliance-only situation. if you're on SAS-2 or later, do not pass it, or you might get an abridged response back. noted. 🫶

🌈 EXAMPLES 🌈

⭐ CONFORMING TO ⭐

The SMP REPORT PHY SATA function was introduced in SAS-1 . The "Expander change count", "STP I_T nexus loss occurred" and several other fields were added in SAS-2 .
