How to build a Virtual Tape Library using Quadstor VTL on RHEL 7 or Centos 7 machine

1. Download rpm from https://www.quadstor.com/vtldownloads/quadstor-vtl-ext-3.0.56-rhel.x86_64.rpm 2. Install pre-requisites as described here https://www.quadstor.com/vtlsupport/145-installation-on-rhel-centos-sles-debian.html 3. Reboot 4.

Assuming there is a unused disk /dev/sdb. on the web interface, Physical Storage -> Add b. Wait for Initialization to complete and disk ID assigned c. Virtual Libraries -> vtl1 -> Add vCatridge d. Load the tape to the drive. 7. The machine that will be using the virtual tape driver ## install iscsi intiator packages and mt (magnetic tape tools package) yum install iscsi-initiator-utils mt-st iscsiadm --mode discovery --type sendtargets --portal <ip of VTL> note the target name. iqn....autoloder (the robot), iqn....drive1 (the drive) iscsiadm --mode node --targetname <iqn name> --portal <ip of VTL> --login lsscsi - note the device names e.g. /dev/st0 ## check status with mt -f /dev/st0 status sample output: SCSI 2 tape drive: File number=-1, block number=-1, partition=0. Tape block size 0 bytes. Density code 0x49 (Quantum SDLT320). Soft error count since last status=0 General status bits on (1010000): ONLINE IM_REP_EN
