RLS is not needed (although it is supported for HSM CDS). All that is needed is extended addressability (also support).
However, this requires converting the HSM CDSs to SMS Management. I have done this with a "do nothing" MCLAS/DCLAS/SCLAS set of constructs.

I'm looking at expanding the file to be multi-volume and wondering if this can be done without converting CDS to RLS? Done some searches but don't really come up with anything. How would this be expanded to multi-volume. Would the definition just be, let's say 20,000 cylinders and make sure there are two mod9 volumes available? One option would be to move it to a Mod-27 but not sure if such a volume is available at our DR site. Anybody have any ideas? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ::DISCLAIMER:: -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- The contents of this e-mail and any attachment(s) are confidential and intended for the named recipient(s) only.
