Unassigned Devices ( Vanishing Drives )

Featured Replies

I'm not sure if this has to do with the latest UPDATE but here's the issue.

 

When hot swapping a drive in the past; the drive would immediately show up as an Unassigned_Devices and now, they don't!

 

I've tried the following:

 

Plugged drives into all the available bays, nothing.

Deleted Unassigned_Devices and Reinstalled, nothing.

 

The only thing that works is to [ REBOOT ] the server.

 

As you can see a before and after screenshot. Before, the reboot, NO DRIVE, after the REBOOT the drive miraculously appears ready to be MOUNTED.

 

Any help would be greatly appreciated!

Thank you.  I will give that a shot and report back.  I wonder what is the cause of the issue.

Thanks testdasi! Worked! Screencaps attached.

 

1. 4th drive installed and does not show up

2. 4th drive installed and rescan-scsi-bus was executed.

3. 4th now shows up as an Unassigned_Device

 

Question for everyone... This was not a "THING" prior to the update. Is this a bug that needs to be worked out or are we just going to have to re-scan the drive each time we hotswap a drive?

 

Thanks all!

Try clicking the double arrows next to the complete switch at the top of the UD page.  This should rescan for devices.

 

Do you have hot swap enabled in the bios?

Thanks for the double arrow rescan tip.  As for the mother board, yes. It’s set for hot swap and nothing has changed

since the stable 6.7.2 update.  It’s a brand new install with no data on the main 16TB of drive.

Nope! The rescan button does not work. Still the command line or reboot is the only remedy.
