Configuration

The virtual ETERNUS CS tapes must be allocated to a location of their own with the ROBAR-2 operating mode for them to be distinguished from real tapes. The following steps must be performed:

1. The location for virtual tapes is defined in MAREN:

   The new location is added to the MAREN catalog with the MARENADM statement MODIFY-MAREN-PARAMETER. The location name can be freely selected, e.g.:

   //MODIFY-MAREN-PARAMETERS LOCATION-ENTRIES=*PARAMETERS
      (LOCATION-NAME=CENTSTOR,ACTION=*ADD(OPERATING-MODE=*ROBAR-2))

   If several virtual archive systems are used, a separate location must be defined for each of them.

2. The virtual archive system is defined in the device administration of the BS2000 systems of the systems concerned:

   The virtual ETERNUS CS devices are included in the I/O configuration with device type code C4. The virtual devices are allocated to a location defined in MAREN for the virtual ETERNUS CS tapes with the command ADD-DEVICE-DEPOT input via the console, for instance to the location CENTSTOR:

   /ADD-DEVICE-DEPOT UNIT=(V1,V2,V3),LOCATION=CENTSTOR

   The allocation is only valid in the current system session.

   Unconditional unloading of virtual tapes should be set for virtual tape operation with ETERNUS CS (as it should also be for real archive systems):

   /MODIFY-MOUNT-PARAMETER
      UNLOAD-REL-TAPE=*REGARDLESS-OF-USER-REQUEST(TAPE-FAM=*MBK)

3. The virtual archive system is defined in ROBAR:

   1. The location must be defined in the ROBAR configuration file using the same name:

      LOCATION=CENTSTOR

   2. When the ROBAR rule file is installed, the version for ETERNUS CS must be used. The rrf_dir parameter must not be used.

   For further details, refer to the “ROBAR” manual [19].

4. The virtual tapes are defined:

   The virtual tapes must be defined both in ETERNUS CS and in the MAREN catalog.

   The desired number of virtual tapes is defined in ETERNUS CS HE using the OCI (Operator Console Interface). Refer also to the “ETERNUS CS” manual [9]).

   ETERNUS CS’s virtual tapes are added to the MAREN catalog as free tapes of the type TAPE-C4 using MARENADM:

   //ADD-FREE-VOLUMES ...,FREE-LOCATION=CENTSTOR,DEVICE-TYPE=TAPE-C4

   If an ETERNUS CS HE archive system  with its already existing virtual tapes  must be included in a MAREN configuration, then the virtual tapes must be added to the MAREN catalog as reserved tapes (you must find the archive numbers in ETERNUS CS ):

//ADD-RESERVED-VOLUMES vsn1(USER-ID=...,DEVICE-TYPE=TAPE-C4,
      LOCATION=*PAR(HOME-LOCATION=CENTSTOR,FREE-LOCATION=CENTSTOR,
      TEMP-LOCATION=CENTSTOR))
