Re: How to use image catalogs

["Larry \"DrFranken\" Bolhuis" <midrange@xxxxxxxxxxxx>]

Darryl,

	What happens when you save to a tape library and the tape fills and 
there are no more tapes? Same thing: "Please add more tapes."

	So just as you need to do with a physical library you need to assure 
that sufficient volumes are available or you'll run out and get these 
messages.

	One thing to know about Virtual tape as compared to virtual optical, 
and it's important: Virtual optical volumes consume the allocated size 
at the time of creation. With virtual tapes they consume just KBytes at 
creation time so there is little reason not to create sufficient 
volumes. DO NOTE however that INZTAP against a virtual tape will not 
reclaims the space previously allocated, you do need to delete and 
re-add if you want to get the space back. Doing that is your call of 
course as you may want to leave the space allocated to assure it is 
available.
