"what DFDSS does with respect to DUMPing and COPYing zFS filesystems, quite the nightmare "
Hey Tom, In the tiniest chances that you're seeing some zFS not being updated, I would suggest reviewing the DSS dump job to see if all he zFSes you intended to dump got dumped. I learnt only recently that DUMP will just ignore migrated datasets; good thing I checked the count of my source 'Service' zFS files against the 'resvol' zFS set. – Vignesh Mainframe Infrastructure -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Tom Conley Sent: 14 February 2018 19:35 To: [email protected] Subject: [EXTERNAL] Re: Best Practices for z/OS Maintenance On 2/14/2018 7:58 AM, Tom Marchant wrote: > /SERVICE/ alone cannot handle more than one release (or maintenance level) > concurrently. > > What I was talking about was using Automount to manage /SERVICE in a manner > similar to the way many shops manage /u.

It would solve one problem I have with cloning zFS's, where DFDSS does weird (stuff) if the zFS filesystem is mounted. Currently have a six-month PMR open with IBM trying to hammer out exactly what DFDSS does with respect to DUMPing and COPYing zFS filesystems, quite the nightmare. I may owe you a beer Monsieur Marchant.
