Hello all, OS RHEL 8.8 AMD cyberpowerpc.

I have 3 external hard drives I'm trying to use but only one is showing at the os level. 3 are raw drives for oracle asm. I tested to make sure power was good and sata ports worked on the motherboard. All 3 show up at the bios page, do I need to make changes there? I changed different settings and it make some show up and disappear. Any assistance would be greatly appreciated. I didn't save any of the bios settings yet to test. All hdd have same capabilities

Hi, in SATA Operation Mode. Select AHCI and Save Exit. After booting check to see if all drives are visible.

Hello Kalana,

Same thing.

Only one showed up.

They still show at boot up

Hi David,  It could be in need of formatting or not initialized by Windows itself. Now that we directed to AHCI, yet the device status being unknown or not initialized or the disk space being unallocated could cause this.

Right-click This PC - File Explorer and choose Manage
Go to Disk Management and right-click your any of your hard disk that's not visible. And choose the Initialize Disk.

Select the disk you wish to initialize and choose the MBR or GPT partition.

When initializing a hard drive for the first time, choose MBR if the drive is 2 TB or less. Choose GPT (GUID) if you have a larger-than-2-TB hard drive that you would like to use but not to boot from.

See if this works.

I'm running RHEL8, so I'll find the equivalent.

Sorry I didn't know. And I'm actually not familiar with RHEL8.

I had the system down for 4 days fired it up and all disks are now showing in lsblk.

Not sure why but they are there

I see, probably didn't recognize the changed settings from the BIOS first time. I'm glad it worked.
