Staying Prepared for a Disaster (with a Tape Management Product)

The following scenarios demonstrate the use of DRM with a tape management product.

  1. To prepare for a possible disaster, the administrator records the following site-specific recovery steps in the INSTR stanza source files:
  2. Define a device class with a prefix of DR for TSM volumes:
    define devclass disaster devtype=cartridge prefix=dr
    
  3. Define a copy storage pool, DRCOPYPOOL, associated with the device class defined above. Set the REUSEDELAY parameter to 30 days (which matches the value set by the SET DRMDBBACKUPEXIPREDAYS):
     define stgpool drcopypool disaster pooltype=copy
      reclamation=100 maxscratch=10000 reusedelay=30
    
    Note:
    The reclamation is turned off for disaster copy storage pool so that the partially filled copy storage pool volumes will not be reclaimed before they are moved offsite. You need to schedule the reclamation for your disaster copy storage pool volumes periodically.
  4. Issue one of the following sets of RMM commands
