Re: How to use image catalogs

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.

I have used them for a long while, however, I am now using SAVLIB to image
catalos.

My problems are:
1. getting the image catalog name to display. Getting QIMGCTL for the name
and then a blank name for the file containing the saved library.
2. Some of the libraries are large and fill the image entry. I don't see
how IBM intends us to use the images.
3. I am getting full images and the job gets interrupted wanting a new
volume. Can I monitor for the prompt for a new volume or does that only go
to QSYSOPR.

694645 blocks processed for sequence 241, volume Q00085, on device

TAPVRT01.

No volume to mount on device TAPVRT01. (C "cartridge id")

? vol111

Volume VOL111 not under media management control.

End of volume detected for file QSYSTAP in QSYS.
? G

My process is:
- Create the virtual tape device
- CRTIMGCLG
- ADDIMGCLGE
- LODIMGCLG
- SAVLIB to TAPVRT01
- SAV to TAPVRT01
- SAVSECDTA to TAPVRT01

I am able to do a DSPTAP TAPVRT01

Thanks, Darryl Freinkel.
