Troubleshooting
Problem
Parallel Save appending to tape when Append to Media is *NO. This occurs when the first entry in the control group cannot be saved in true parallel format.
Resolving The Problem
In V5R4 and above, BRMS allows users to create a control group that will do parallel saves and allow entry of items that cannot be saved in parallel. For example, *SAVSYS, *SAVSECDTA, *SAVCFG, and *ALLDLO cannot be saved in parallel. However, you can list these items in a control group processing a parallel save.
In a situation where the control group attribute 'Append to Media' is set to *NO and the first item in the control group cannot be saved in parallel (for example, *SAVSYS, *SAVSECDTA, *SAVCFG, or *ALLDLO) when the control group saves an entry that can be saved in parallel, BRMS looks for a volume that can be appended to even though 'Append to Media' *NO is specified. This is a current restriction in BRMS.
For example, if the following control group specified 'Append to Media' *NO and a parallel backup was specified, when the *ALLUSR portion of the control group is processed, BRMS will attempt to append this save to an active volume:
Back up
| Seq | Items |
| 10 | *EXIT |
| 20 | *SAVSECDTA |
| 30 | *SAVCFG |
| 40 | *ALLUSR |
| 50 | *EXIT |
To prevent an active volume from being appended to, use one of the following circumventions:
Circumvention 1: The first save entry in the control group must be a parallel item (for example, *ALLUSR, *IBM, *LINK). Following is an example:
Back up
| Seq | Items |
| 10 | *EXIT |
| 20 | *ALLUSR |
| 30 | *LINK |
| 40 | *SAVSECDTA |
| 50 | *SAVCFG |
| 60 | *EXIT |
Circumvention 2: Keep the items not saved in parallel at the top (such as *SAVSECDTA) in the control group. Then, load a volume between the nonparallel items and the parallel items. You can use the special operation *LOAD to begin a new tape. Following is an example:
Back up
| Seq | Items |
| 10 | *EXIT |
| 20 | *SAVSECDTA |
| 30 | *SAVCFG |
| 40 | *LOAD |
| 50 | *ALLUSR |
| 60 | *LINK |
| 70 | *EXIT |
Circumvention 3: Create two control groups. One control group should save only parallel items, and the second control group should save the items that cannot be saved in parallel. Following is an example:
Control Group 1:
Backup
| Seq | Items |
| 10 | *EXIT |
| 20 | *SAVSECDTA |
| 30 | *SAVCFG |
| 40 | *EXIT |
Control Group 2:
Backup
| Seq | Items |
| 10 | *EXIT |
| 20 | *ALLUSR |
| 30 | *EXIT |
