We are using RHEL 7.5 customized for our use and install We have our own kickstart which uses list-harddrives and parted to check on the Disks and partition accordingly. Disks are in RAID 10 configuration Intermettently we see that the Installation destination "No disk selected". Rebooting the system and trying again - this works and install goes thru with a question. Any suggestions on how to debug this further - and what are the possible points to check
