Description Dennis Gilmore 2020-01-16 20:17:52 UTC

Description of problem:
In OCP 4.2 we are only supporting FCP disks via single-path and not multi-path as is normally done. this is due to the support for multi-path taking too long to land in RHEL CoreOS.  We need to document the limitation and add a note that if you need redundant paths to the disk you need to use DASD disks in OCP 4.2
