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.

In Unity 5.5, File System (FS) access can be provided using a Network File System (NFS) mount using NFSv3 or NFSv4 file sharing protocols. This is typically done for Logical Unity Numbers (LUN) and NFS datastores with specific mounting parameters and then scripted for various groups of hosts. A directory is created for the mount point when mounting file shares using NFSv4.2. If the directory security label (sec_label) parameter has no data assigned to it, the Unity Service Processors (SP) can panic and reboot unexpectedly.
