Our Host Configuration guide for Linux (as of September 2023) reads, page 136 : “Red Hat Enterprise Linux 7.4 and later The Red Hat Enterprise Linux 7.4 introduces detect_checker as a stanza parameter. The default value is yes. The MPIO detects if a device supports ALUA. If ALUA is supported, the MPIO overrides the configured path_checker, and uses the TUR checker instead. For Unity, and VNX, it is recommended to use emc_clariion checker as it can handle the inactive LUN state properly.” When applying this recommendation in a RedHat 7.x environment (with x greater or equal to 4), an error is returned by multipathd saying that this parameter is invalid.
