Configure DD VTL Tapes in NetBackup

Steps to configure DataDomain VTL tapes in NetBackup:

•  Check HBA details: 
•  fcinfo hba-port
  
•  List current configuration using: 
•  cfgadm -al
  
•  Configure the appropriate controller:
•  cfgadm -c configure c10 or cfgadm -c configure c10 -force
  
• Scan Solaris for new devices:  
• devfsadm -v
  
•  Check devices in /dev/rmt location:
•  ls -lrth /dev/rmt/*
  
• Check for scsa drivers: 
• modinfo | grep -i scsa
  
•   Unload sg driver:
•   modunload -i  213 (only sg driver)
  
• Backup current sg.conf file:  
• mv /kernel/drv/sg.conf /kernel/drv/sg.conf.orig
  
• Build new sg drivers:  
• cd /usr/openv/volmgr/bin/driver/
•   ../sg.build all -mt 30 -ml 40 ('mt' and 'ml' values can be selected based on environment)
•   ./sg.install
  
•   Scan for new drives and robots:
•  .tpautoconf -r (detect robot)
•   tpautoconf -t (detect tapes)

Note: This document assumes VTL configuration has been done on Data Domain before running the above given commands. Also the above steps implies the OS is Solaris. Linux or other Operating systems may have different commands to execute
