Greetings: 3 x servers each server has 1 x 512GB ssd 2 x 1TB SSD JBOD Goal: use HCI disk setup wizard to deploy initial structure Each server has disk scanning in as different /dev/sd# and so trying to use more clear /dev/mapper/<disk ID> As such I set this per table below: # Select each server and set each drive <<<<<<<<<<Double Check drive device ID as they do NOT match up per host # I transitioned to /dev/mapper object to avoid unclearness of /dev/sd# thor /dev/sdc /dev/mapper/Samsung_SSD_850_PRO_512GB_S250NXAGA15787L odin /dev/sdb /dev/mapper/Micron_1100_MTFDDAV512TBN_17401F699137 medusa /dev/sdb /dev/mapper/SAMSUNG_SSD_PM851_mSATA_512GB_S1EWNYAF609306 # Note that drives need to be completely clear of any partition or file system [root@thor /]# gdisk /dev/sdc GPT fdisk (gdisk) version 1.0.3 Partition table scan: MBR: protective BSD: not present APM: not present GPT: present Found valid GPT with protective MBR; using GPT.
