Faulty luns

Dear Sirs,

A hard drive got faulty in our eva4000 san. This affected about 3 virtual disks which were all in raid5. This disk have been replaced but we do not see any sign of the virtual disks rebuilding automatically. Do i have to do it manually?

Thank you

Did you group the replaced disk?

If enough space available, the RAID will be balanced to get redundant immediately after the disk failure, so if you replace the disk, the array will ONLY level the data across the new disk. This may start later.

But in my case it did not happen that way. All the virtual disk were marked red and after the replacement the system asked us to click on a tab and continue which i did. What we rather realized was that all those virtual disks got missing.

Thank you

Sounds bad. Sure it was RAID5, not RAID0? It depends on what selection you clicked, but at this point you should involve HP support (even it is a bit late now ...).

If you didn't have VRAID5 maybe a second disk broke.
Or, you replaced the wrong disk.

"after the replacement the system asked us to click on a tab and continue which i did"

What did it say?
