Ungrouped two failed FATA 1TB disk
The two disks in the group happened to loose one of their port connection at around the same time. From the eventlog it said that to ungroup the disk and then replace that. There is no orange light on the disk.
I would like to ungroup one of the disk and wait for the leveling process to complete and then add in the replacement disk and add that to the group and wait for the leveling process to complete. Once that is complete ungroup the next disk and repeat the above procedure.
What if the other disk looses both of its connection an failed when the leveling process is still running? Do a loose data on that Disk group? The current protection level is Single.
Someone can confirm or give a better way of solving that issue.

Re: Ungrouped two failed FATA 1TB disk
If one loop connection was lost and is now back, you may consider to check controller and disk firmware.
Sometimes an update already fix the problem.
Hope this helps!

Re: Ungrouped two failed FATA 1TB disk
If you have to re-seat a disk, increase the failure detection interval before you pull the disk.
> The current protection level is Single.
The so-called "protection level" does not protect your data. Think of it as virtualized spare disks. The redundancy is in a virtual disk's VRAID-1, 5 or 6.
VRAID-0 does NOT offer any redundancy against disk drive failures - no matter how many objects on the EVA have the words "protection" or "redundant" in them.

Re: Ungrouped two failed FATA 1TB disk
Initially you can re-seat the drives within 10 seconds and check.
If possible can I request you to post the EVA logs (Controller Event Log and Configuration log) here.

Re: Ungrouped two failed FATA 1TB disk
As others suggested, first thing to look here is firmware. If that is current you can look for replacing the disk after verifying the status (levelling or re-construction).
