Creating an Image Catalog to be Used with a User or Independent ASP

Resolving The Problem

This document describes how to create an image catalog so that its volumes are used in a non-system ASP. The benefits to using a separate ASP include performance, data resiliency, and organization. The specific example is for a tape image catalog in a basic user ASP; however, an optical image catalog and/or independent ASPs can be used as well.

For this example:

UDFS name in ASP02: QASP02.udfs
Mount-point directory name: /asp02
Image catalog name: BACKUP
Image catalog directory: /asp02/backup
Volume name: VOL001
Virtual tape device: TAPVRT01

1.	CRTUDFS UDFS('/dev/QASP02/qasp02.udfs') User-defined file system created.
2.	CRTDIR DIR('/asp02') Directory created.
3.	*MOUNT TYPE(UDFS) MFS('/dev/qasp02/qasp02.udfs') MNTOVRDIR('/asp02')** File system mounted.
4.	CRTDIR DIR('/asp02/backup') Directory created.
5.	*CRTIMGCLG IMGCLG(BACKUP) DIR('/asp02/backup') TYPE(TAP) CRTDIR(NO)* Image catalog BACKUP created in library QUSRSYS.
6.	*ADDIMGCLGE IMGCLG(BACKUP) FROMFILE(new) TOFILE(VOL001) VOLNAM(VOL001)** Image catalog entry added to image catalog BACKUP.
7.	*LODIMGCLGE IMGCLG(BACKUP) IMGCLGIDX(1) OPTION(MOUNT)** Image catalog entry 1 mounted.
8.	*CRTDEVTAP DEVD(TAPVRT01) RSRCNAME(VRT)** Description for device TAPVRT01 created.
9.	*VRYCFG CFGOBJ(TAPVRT01) CFGTYPE(DEV) STATUS(ON)* Vary on completed for device TAPVRT01.
10.	LODIMGCLG IMGCLG(BACKUP) DEV(TAPVRT01) Image catalog BACKUP loaded in device TAPVRT01.

At this point, when device of the save command is specified as the virtual device, the objects will get saved to the virtual volumes that are located in the user ASP.

Note: When creating the image catalog, the directory cannot be the mount-point directory; however, it can be a subdirectory of the mount-point.
