Considerations and information about DSI VTLs

If requiring sizing for Dynamic Solutions International (DSI) Virtual Tape Library (VTL), send the following information to IBMsizing@dynamicsolutions.com

  1. Customer Name
  2. What VTL/Tape drives are used today
  3. If using a VTL,
    1. What is the current deduplication ratio
    2. What LPARs are been saved at what location if there are multiple sites
    3. Average size of virtual volumes
  4. Data collected from one of the actions below
  5. If using a mixture of VTL and physical and you are planning on continuing the same practices, list control groups that will use physical media
  6. These commands need to run in the same job stream.
  7. The PRTRPTBRM EXPDATE(*ACTIVE) parameter was introduced in 7.2 and later and requires one of the following PTFs: 7.4 SI72867 7.3 SI72866  7.2 SI72865

If using BRMS backup control groups, load and apply 7.3 SI693904 SI72867 7.2 SI693893 SI72866  7.12 SI67311SI72865 or superseding PTF and then run the following commands on each LPAR and send the spooled file. The spooled file can be zipped to transfer easier.

  • CRTDTAARA DTAARA(QTEMP/Q1ARPTRETN) TYPE(*CHAR)
  • PRTRPTBRM TYPE(*CTLGRPSTAT) EXPDATE(*ACTIVE)

Send the spooled file in text (.txt) format. (The files need to be downloaded as .txt files, not as .pdf and converted. See the BRMS-Report gathering.docx.) NOTE: Both these commands need to run in the same job stream

If you have multiple systems in a BRMS network, you can use the following command on one of the systems to run the reports for each the other systems

  • CRTDTAARA DTAARA(QTEMP/Q1ARPTRETN) TYPE(*CHAR)
  • PRTRPTBRM TYPE(*CTLGRPSTAT) FROMSYS(xxxxxxxxx) EXPDATE(*ACTIVE)  CAUTION: Do not use *NETGRP or list multiple systems

Send the spooled file in text (.txt) format. (The files need to be downloaded as .txt files, not as .pdf and converted. See the BRMS-Report gathering.docx.) 

NOTE: Both these commands need to run in the same job stream

If not using BRMS control groups or not using BRMS, send in the following for each LPAR . You can use RTVDSKINF and PRTDSKINF to get library and IFS sizes.

  • Type of backup -  Daily, , weekly, monthly, yearly etc
  • Size of each backup
  • How often each backup is done - Example : Daily 6 days a week, Weekly once a week,
  • Retention of each backup - Example : Daily 14 days, Weekly 35 days
  • Start time of each backup
