Do the vendors support migrating between vendors? Or is this vendor specific? yes, one vendor I used migrated from DASD from company A to DASD from company B. we used a third party vendor that is a partner with IBM and we used FDR for one migration to migrate the DATA but as others have said, there are a number of tools that run on Z that can migrate the data for you seamlessly one vendor provided a solution when the box was replicated without the need to run anything on Z, > some provide a tool to replicate the data, flip the switch > (figuratively) and you are now running on the new DASD subsystem. > (once DASD is cabled and new GEN is activated) I was naively thinking that there might be a way to do this within z/OS. there is, but most resellers provide services and tools to aid in the migration or do the migration for you. very simple to use DFSMS/DSS ADRDSSU to copy and flip the volser if you choose to do this yourself AIX / Linux / Solaris / Windows offer an ability to add new disks to (special) storage volumes, copy / migrate data between them, and remove the old disks, all as part of contemporary OS versions. Special meaning that the storage is provisioned with this in mind in the beginning. Each OS is slightly different in this. Note how this is done at the OS level and does not require external vendor support. pretty much the same for Z.. Does z/OS have anything similar? Or is storage fundamentally different? depending on your requirements the storage can be partitioned the way you like, most sites I've worked all DASD was used in a production environment containing volumes within storage pools, every site is different. we currently have a # of UCB's available to use and a limit of storage, if I need more storage, I add more volumes to a storage pool, simply put. > I've been a part of a couple different migrations at different shops, > all were non disruptive. :-) > as with any new subsystem, you need to make sure you have the > toleration maint for the subsystem you are installing, and the > functions/features you are going to use, P2PRC....for example Prerequisites always exist. -- Grant. . . . unix || die ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
