Additional software for EMC devices

Before you can use an EMC Symmetrix device in a hardware snapshot or any EMC-specific functions from the XBM ISPF monitor, you must have one of the following:

  • EMC Symmetrix Control Facility (SCF) subsystem installed and functioning
  • EMC devices that support Flashcopy (contact EMC for licensing information)

Warning

Important

  • If you use EMC SCF, the EMC SCF link library contains the required API modules that were previously shipped with XBM. To obtain the necessary EMC components, contact Dell EMC and request the most recent version of the ResourcePak-Base for OS/390 and z/OS.

  • SPE2011

     If you want to use the features that EMC SCF version 7.6.0 or later provides, we recommend that you apply PTF BPE0482. If you are using EMC DASD, we recommend that you install EMC SCF version 8.1 or later. 

  • Applying PTF BPE0482 is a prerequisite for all future SUF and XBM product maintenance. 

EMC Symmetrix devices also require certain levels of microcode to be installed on the devices themselves to support different snapshot methods. The following table lists the minimum required EMC microcode levels:

Required EMC Symmetrix microcode levels

Hardware snapshot type

Required EMC microcode level 1

Volume-level

5x63 or later

Data-set-level

5x66 or later

For more information about the SCF and EMC microcode, see your EMC Symmetrix documentation.

If you have EMC TimeFinder version 5.3.1 or later, you might need two EMC products. If you are doing mirroring, you will need the EMC TimeFinder/Mirror product. If you are doing data-set-level or Instant Snapshots, you will need EMC TimeFinder/Snap. EMC separated the mirroring and snap capability in the 5.3.1 release of EMC TimeFinder. For more information, see the EMC documentation.

Warning

Important

If you have the EMC Symmetrix Automated Replication (SAR) feature of SRDF in your environment, XBM will not use active members in a SAR relationship for snapshot processing. XBM recognizes these volumes and automatically bypasses them to use alternate BCVs. Doing so avoids any potential conflicts from occurring between the EMC SAR feature and XBM.
