[QUOTE="FlyerKumar, post: 1934523, member: 419163"] Does Apple 🍎 still support multipathing as indicated in this [URL='https://developer.apple.com/library/archive/technotes/tn2173/_index.html']Technical Note TN2173: Multipathing with FibreChannel on Mac OS X[/URL] on the Apple 🍎 website, in the current versions of Apple 🍎 macOS and if not, when (what version of Apple 🍎 Mac OS X or macOS) was it removed or discontinued? Was it only implemented only for Fibre Channel (and that too only for the Apple Fibre Channel cards which presumably were made for Apple 🍎 by then-LSI Logic, now since part of Broadcom, or any Fibre Channel HBA?) or was it implemented for (or compatible with) SAS (Serial Attached SCSI) as well given that all SAS drives are dual-ported and support multipathing for redundancy and redundant paths to access them in addition wide-port mode for additional bandwidth? If it still exists in currency versions of macOS, does it support only Fibre Channel or does it also apply to and support SAS HBAs and/or RAID controllers? How would one access the macOS interface for it? Is there a GUI in macOS to access the multipathing settings or is there a terminal utility or set of terminal commands to view the status and settings and/or to configure it in macOS? [/QUOTE]
