Many customers have various types of media and tape drives. They want to use one type of media for an offsite backup, another for their weekly base backup and yet another for the daily incremental. What steps are necessary to get CA VM:Tape and CA VM:BACKUP HiDRO to function within these parameters?
VM:Tape and EDRSUP
If new devices are going to be added to the configuration, and EDRSUP is not currently turned on in VM:Tape, it is highly recommended that when the new devices and SERIES records are put in place that EDRSUP is also.
To turn on EDRSUP: On VMRMAINT's 192 disk you will find the VMISTART COMMANDS file. XEDIT it, on the COMMAND VMTAPE record, add EDRSUP after VMTSYS such as:
COMMAND VMTAPE<xxx> VMTAPE VMTSYS EDRSUP
To determine the correct DENSITY and MEDIA settings for the new devices, review the CA VM:TAPE System Administrator Guide, Chapter 4 Getting Started, Density and Media Settings, and Chapter 8 Configuration File records for DEFDENS and DEFMEDIA. If the new devices are not listed, please check our Support website for Informational apars we have published specific to device support. If they are not yet supported, please contact Customer Support.
Currently your site has IBM 3490E's and 3590's, adding new 3592's
Density ENHXF or ENH
Density HPTC or HPTB
Density ETCB or ETCCImplemented in HiDRO r2.7D genlevel 0504, SYBVMTAP EXEC has a 'stub' called SYBVMTXX. It is loaded to the 201 disk of HiDRO as SYBVMTXX EXECSAMP. Copy it to the 191 disk of HiDRO and give it a filename of EXEC. Modification(s) to this 'stub' is what allows HiDRO to send VM:Tape on the MOUNT command the right media/density/pool name. HiDRO works best with only one choice of drive through the Defaults. This new method was chosen for more flexible communication with VM:Tape.
Change the top to specify what is going to be used most often..
DRIVE = '3490E'
media = 'ENHA'
DENSITY = 'ENHXF'
vmtpool = 'name' <=====if used.. or remove
anytape = 'NO' /* Must be YES or NO */
MODIFIED = 'YES' /* MUST BE YES OR NO */
create sets of records like this..
When jobname = '3592JOB' then do
modified = 'YES'
density = 'ETCC'
media = 'ETC'
drive = '3592'
