Hello Victor-san, I could not find out document which describes "multiple TS7740 CANNOT share a physical TS3500 WITHIN a Grid".
A physical TS3500 tape library provides multiple logical libraries. Each TS7740 VE (Cluster) in a Grid uses a logical library of TS3500. So there is no explicit reason that multiple TS7740 clusters in a Grid cannot share a physical TS3500 tape library. Then my answer is "Yes, you can". Please note that if you share a physical TS3500 from TS7740 clusters in a Grid, the TS3500 might be a single point of failure of the TS7740 Grid, if the TS3500 does not have High Availability feature. Please refer to Chapter 6.2 Partitioning a TS3500 for System z hosts of Redbook "IBM TS3500 Tape Library with System z Attachment A Practical Guide to Enterprise Tape Drives and TS3500 Tape Automation" SG24-6789-03. http://www.redbooks.ibm.com/abstracts/sg246789.html?Open P.S. I'm not a Minor. I'm an aged major. ;-) Minoru Massaki (M*M) 2011/8/16 Victor Zhang <[email protected]>: > Minor, > Thank you. > May you answer another question: > Can multiple TS7740 share a physical ts3500 within a GRID?
