Backup & Recovery

Abstract:

This document describes the ten relatively easy steps to provision an instance of an iSCSI based mhvtl server.  This is followed by a further five steps which you can follow if you want to onboard the mhvtl "tape" functionality into NetBackup.

The associated script automates the 30 or so otherwise tedious steps in provisioning a mixed media "mhvtl" instance of one virtual tape library, plus four virtual tape drives, plus 38 virtual media each of 1GB.  The four virtual tape drives are implemented as two LTO4 plus two LTO5 virtual tape drives, and the virtual media are in two sets, one of 19 virtual LTO4 media, and another of 19 virtual LTO5 media.

.

...see the attached for the entire procedure.

Remember to save the script as a ".sh" file.

Hi SDO,

Is this the latest Mark Harvey VTL? Have not heard of it in long time now...

Yes, the script always downloads (and compiles) the latest version of Mark Harvey's "mhvtl" from GitHub.

Great job SDO

Now also tested to work ok with Windows 2012 R2 running NetBackup Master/Media Server v7.7.2.

The mhvtl and tgt versions were:
