1) If possible move backups that use effected DSSU staging unit to another pool. Our storage team was able to present a temp 16 TB lun to give me the space to move the backups policies around to use alternative staging units.

2) Manually BPDUPLICATE (Catalog Tool) data tick box make primary copy.

3) Expire all none "primary no" images.

4) Increase high and low water marks to 90 / 70

5) Enable schdeuled duplication process

6) Track all new normal duplication jobs and cross reference against physical view at ls -lrt or explorer level

7) You will get a lot of inital 190 errors from the normal duplication process but this will clear as the expired images are cleared from the system.

Please feel free toy drop an email if you get stuck I spent a month fixing our site and encounter of copy issues escpecaill the way the copy number system works the rule of thumb is

"

Expiring a non-primary copy does not change the primary copy.... if the primary copy is expired, the lowest numbered remaining copy is tagged as the primary.

Copies are numbered in the order they're made... so copy 1 will always be the first copy taken.... their duplication process is tagging copy 2 as the primary, but it IS copy 2, not copy 1
