ASE : How to increase the size of existing device

Sybase 12.5 has a nice new feature to expand the size of existing device. In the past, the only way to add space to a
database is to create a new device, then expand db on the new device. Now we have anther option. Below is the usage

disk init
name = ‘existingDevice’,
size = ‘additionalM’
Please note, this is to add space to exisiting device. i.e the device is 100M, the following command will make the
device 500M

disk resize name = testDev, size = “400M”
