5 disks failed on EVA

[NDO]

Hi

I have an old EVA4000 with 2C4D configuration and 1 DG, for some reason I found out 5 disks that are in a failed state, I have replace one, for now, the in command view eva, its shown as leveling, and it looks like is going to take hours if not days until that leveling is 100% status.

Can I replace anothe disk? or should I wait until the leveling is done? How can I view if the failed disks belong to the same RSS?

If a disk in an EVA fails, the array starts to reconstruct and get redundant again as long as there is enough free space.

So if there is enough space and "enough" time between disk failures, your array will be fully redundant after the disks failures.

A failed disk is no longer part of a RSS group.

Replace all the disks and group them all at once.

As for storage capacity, I have the following:

Total: 10102.35 GB

Used: 9115.86 GB

Available: 986.49 GB

I have already replace 1, and leveling is a 6%. Shall I go ahead and replace the remaining 4?

If you see "reconstruct" you need to wait. Don't wait for leveling.

At the Conditional/State, header I see:

Operational state: Atention

Leveling state: In progress

Leveling progress: 9% leveled

RSS Disk state: none

[Torsten. · Accepted solution]

Replace the disks now, select the DG and group the new available disks all at once. So the EVA needs to do a single leveling but not level 5 times.

Done, the leveling has gone back to 0%

Does the leveling process slows down the servers with file systems on the EVA?

If you select one of these disks now, you should see the occupancy level growing.
