Hi John, Apart from the z/OS-inbuilt Volume Mount Analyzer, you could look at 2 other items for reviewing your tape activity:
1. IBM has a utility called tapetool that mainly allows reporting on the TS7700; additionally, they offer a PROC which you can run as STC, which will cut extra SMF records for a detailed look at what's going on. 2. MXG has an alternative to #1 and they call it MXGTMNT; it must run as an STC in every LPAR and writes its own SMF record type. As you'd expect, this data is then analysed using MXG code. It saddens me to not hear a lot about alternative tape solutions (Optica zVT or Luminex MVT). In this day and age, disk has become tape and flash has become disk, so the use cases for actual tape could be growing smaller. – Vignesh Mainframe Infrastructure -----Original Message----- From: IBM Mainframe Discussion List <[email protected]> On Behalf Of Rugen, Len Sent: 30 January 2019 14:56 To: [email protected] Subject: [EXTERNAL] Re: Tape Mount Mangement I probably commented on TMM, because we really benefited using it. We were on mainframe hospice, they weren’t going to improve anything before they killed it, but we had to survive several years of growing usage first. Had we been in your situation, already having a virtual tape appliance, I'm not sure it would have gained much. What would TMM gain for you? I'm not familiar with that hardware, but you shouldn't have to wait long for mounts, you shouldn't be limited on drives and surely doesn't waste storage on short tapes. I don't recall such a cookbook. If I remember correctly, I first looked at demand mounts (non scratch), then at demand mounts that were created in the past 36 hours. If I could put data on disk that was to be referenced soon, it would probably be referenced before it migrated. I repeated that cycle for longer intervals until most demand mounts were eliminated. I also looked for short tapes, where not much data was written. We could satisfy most of our scratch mounts with the autoloaders on the drives, but eliminating the short tapes was just less tapes to shuffle. In our case, we saved a lot of clock time eliminating demand mounts and drive allocation. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN MARKSANDSPENCER.COM ________________________________ Unless otherwise stated above: Marks and Spencer plc Registered Office: Waterside House 35 North Wharf Road London W2 1NW Registered No. 214436 in England and Wales.
