3-hosted iSeries client partitions - how to backup to single tape libaray
Posted on 2016-08-23
I have a 8202-E4D with a single physical partition - on that physical partition I am running 3 hosted client partitions. I am using this for multiple iTerra backup partitions, each partition mirrors a physical machine(Europe,China,North America). I want to backup the 3 hosted partitions to a single attached tape library. The library is attached to a single SCSI controller but I can't dynamically swap that to the hosted partitions because they can't host physical devices.
I think what I need to do is put a virtual SCSI adapter in each hosted partition pointed to the physical adapter in the physical partition - but I am not sure how I make them not interfere with each other, IE multiple partitions trying to vary on and use the same physical device. I know I have to obviously time the backups to not interfere but I have to spread them out to not overlap, since the library has barcode reader to I can programatically move tapes around fine.
Any advice would be appreciated.
