RAID ARRAY CAPACITY EXPANSION

By cooldba ·
Hello,
there is a server (Windows 2000) with two arrays.
Array A with 2 disks, Array B with 3 disks. Array A contain the system. Array B contain the data.
We want upgrade the Array B with new 145GB disk.
Currently we use 36GB disks. How to do this without lost the data ? Is it possible ?

Additional Info: Server W2K, Smart Array 5312 Controller, Adaptec 21960LP SCSI Card. 1 of 6 disk slots are free.

Thx...cooldba

Whenever you ADD a disk to an existing Array it only accesses the amount of space in the existing disks. So your 145GB will act as a 36GB and you won't gain much space for your substantial investment ( I am assuming RAID5 since you have 3 disks in it already).
If you can afford 3@145GB you could replace the current disks if you have a good backup to restore from.
Good Luck,
peter

you must backup your data, configure the new array and restore the data to the new array.
