Proliant DL380 G3 - RAID Question.

Hi everyone,

We have some DL380 G3 Servers with RAID 1 and RAID 5. We intend to buy some spare SCSI hard disks. My question is:
Given RAID 1 running with 2 36 GB disks or RAID 5 with 3 36 GB disks,if one of the disks fails, can we rebuild the mirror or stripe using a bigger capacity hard disk - 72 GB or 146 GB ?

Regards.

Hi. You can not rebuild a other capacity hard disk. It may lead to apparat level error.

Sezgin:

Yes, you can use a larger capacity drive to rebuild a failed drive.

You will only have the capacity of the smaller size available though.

I.E. In your RAID1/2-36GB Disk Array. One fails and you put in a 72. The 72GB disk will act as a 36GB disk and the other 36GB will be lost/un-usable. If you then replace the other disk 36GB disk with a 72, the space will then become available for Extend of your logical drives or creation of new logical drives.
