Database is in Archivelog mode

If so how can we hot swap a drive which is mirrored what steps we need to follow

Thanks,
On a protected device, sure. If your device is RAID 1, 0+1, or 5, you can replace disks on the fly with no problem. The steps vary according to your OS and volume manager software, but in general they are:
1. pull out old disk
2. put in new disk
3. tell your volume manager to resync the disk.

If you have hot spares defined, things will be a little different because you essentially have to do the whole process twice.
