TimeFinder for zos using smc and symcli
I recently implemented SRDF on zos. I'm an Open Systems guy so I used SMC and symcli commands from a windows host. At some point in the future we will use the EMC Host tools on the z but that is in the future. I have not used Time Finder yet but I need to use it to snap/clone Gold Copies on the Remote R2 side. Every week we will change to acp_disk mode for DB2 reorgs. Before doing that I want to get a Gold Copy of all the DB2 volumes on the target side.
At some point we will want to run this Gold Copy clone/snap process from the z host as a scheduled job, but for now I want to run it from the Windows SMC/Solutions Enabler/ECC box. Is it ok to run these Mainframe Time Finder functions from the Windows host? The Windows host has access to all the mainframe volumes from SMC or Solutions Enabler. I would be running the same commands (don't know them all yet) that I would use for open systems Time Finder.

The mainframe and open systems software for TimeFinder /SRDF will perform their function on symmetrix any Symmetrix device. i.e. the sofware doesn't look at the emulation (FBA/CKD).
You may find some advantages running software functions on the mainframe for the CKD devices. For example, you can perform Timefinder against the device address (rather than symmetrix device number). You can also check that the TF target device is offline from a host perspective. Mainframe TimdFinder can perform dataset level SNAP.
These are just a small example of the extra features you can exploit when running TF on the mainframe against CKD devices. There are many prameters available that can influence the TF process in ways that may be beneficial to you.
So in summary each software platform can manage all devices in the Symmetrix. Depending in your requirements, you may find your own benefits in running software functions on CKD devices on the mainframe platform. Checking the SNAP target is offline for instance is a great safety feature that validates the target is offline on all LPARS before SNAPPing to it.
