Adaptec storage manager for 2010S degraded raid 5

Hi Experts,
Drive failed in Raid 5 array (of 3 73gb hd's) and support guys replaced with disk that was too small twice!
Correct size drive has now been installed. Problem is that raid array shows failed drive as missing.
When the hot swap replacement is put in it does not give an option to rebuild array. If I allocate the new disk as a hot spare is it safe to do a "set configuration" which may bring it in to return the array to optimal?
Thanks in advance.

The Raid 5 requires an array of at least 3 drives. The whole philosophy is based on the fact that stripes can be rebuilt. In absence of the 3rd drive your other two drives are effectively rebuilding the data on the 3rd disk. That is why your system is running a bit slow now.

DO NOT make any changes to the array until you have successfully rebuilt the RAID 5 array.

Rule of the thumb. If you use 75 GB drives to create your array then you have to replace them with 75 GB Drives. Preferably the same brand and model (but that is a suggestion not a strict rule).

The reason you don’t have the rebuild option is because it has not recognised the drive. The drive may have been formatted before using other sector sizes. Try re-formatting on the 2010s.

I don’t remember the menu by heart – but I seem to remember
Action -> Format Drive

Chose the correct drive and select OK

I have resolved the issue:
The confusion in the raid setup appears to be caused by the drive not being recognised as a replacement when inserted into the failed drives hot swap bay. When inserted into another available bay it immediately picked it up and started to rebuild. Maybe there is an issue with that bay, i will investigate that later. For now, all is working fine.

Thanks
