Number of disks that can break

Helow
I have a P4400 EVA with 48 disks configured into 1 disk group, the question is, how many disks can be broken without problems
Thank you

Re: Number of disks that can break

"how many records can be broken without problems"? None. Data corruption is bad.

Did you mean physical disk drives? In that case, if you are using RAID1 or RAID5, one disk. If you are using all RAID6, two. When a physical disk fails, replace as soon as possible!

I have one disk group configured with 48 disks and in the Disk Group, I have several Virtual disk that are RAID 1 or RAID 5 .

Contact HPE EVA Support.

Have them help you figure out what is wrong.

If any RAID set is broken (not just degraded due to loss of a drive), the array will stop all IO to the affected virtual disks.

Re: Number of disks that can break

If a disk fails, the array will re-organize to get fully redundant again. Same if the next disk fails after this reconstruction. This works as long as you have enough free space.


Hope this helps!
