I would think HSM would have the same issues regardless of the virtual tape system used. We have an MDL -
As I remember, we set up a new esoteric to use with the MDL. So UNITNAME had to be changed. We used a tape size of 40GB's for the MDL. We changed RECYCLEPERCENT(5). So as not to recycle backup tapes too frequently. We didn't want to spend too much CPU here and have plenty of room in the MDL. Also PERCENTFULL(2) for ML2 tape - we use Rocket Software (OpenTech) TapeCopy/VDR for disaster recovery. At DR we have an IBM library, The limit for tape size is 4GB's. So we ran into issues when trying to restore larger ML2 tapes at DR & found it easier to limit the amount of an ML2 tape used at home. We do not limit the size of Backup tapes as they don't go to DR. ML2RECYCLEPERCENT(10) - we're going to have to check on this one. I'm not sure at this point how this fits with our PERCENTFULL(2). Think's it's 10% valid data from the amount actually written to that tape. We don't use ABARS or HSM dumps. It seems likely that if you do, you'll have parms to at least look at if not change. This is from just a quick scan of our HSM parms. More than likely I've missed something. Hopefully I won't get crucified for it. ddk Hervey, Please post your observations. We are currently looking at various tape solutions for Mainframe and I will be interested to see how Luminex works for you. Lizette -----Original Message----- Hello, We'll be testing a Luminex tapeless solution in our mainframe environment in the next couple of months and just wondering if any of you out there have gone through this type of implementation. If so, any problems encountered migrating the HSM or TSM tape date to this new hardware? Anything to look out for?
