SCSI Hard disk problem

[Dr. Madhurjya P. Bora]

Yes, we talked to the vendor (i.e. IBM reseller) and have ensured that these drives will work with the existing system.

The raid controller does see these new drives, but they are not the part of the array. There is only one array and IBM ServeRAID software that came with the machine does not have any option on it menu to include thsese new hard drives into a separate array. I guess I have to delete the old array and configure from anew.
