failed disks

Hello,

We have an appliance 5250 S series with two shelves 2u12

we get 2 disks failure (1 disk on each shelf), a hot spare drive from each shelf has replaced a failed disk

we have opened an SR with veritas and they are shpping two new disks

our question is the following : what is the situation if another disk get failed before we recieved the new disks?   knowing that the volumes are pre configured with raid6 , does the data will be lost ?

Thanks for your answers :)

 

 

  • With RAID 6, you can survive the loss of 2 disks.
    If the hot spare finishes syncing the data, you will lose data only if 4 disks in the same self fail.

    If the hot spare does not finish syncing the data, you will lose data with 3 failures.

    every self is one Raid 6 volume + hot spare
