Re: What is the differnce between UNIT and VOL Parameter in
Unit and volume specify the location of a dataset.Unit specifies whether the dataset resides in DASD or TAPE
so you mention
UNIT=SYSDA or UNIT=TAPE
VOL specifies the volume seial number
Also here a very good link about the relationship

UNIT defines the type of device. VOL defines the actual tape or disk; this is important when a site may have hundreds of disk volumes and many thousands (even hundreds of thousands) of tape volumes. They are definitely NOT the same -- nowhere near it.
