Max drives utilization in NetBackup backup policy

Hi,

I am using windows2008 server as my master server and have 16 LTO5 drives. when i fire a backup then it is using only 3 drives only but there are 20 streams. when i fire another backup then it will wait until the previous backup is completed after the backup is completed then only the next backup is starts with another three drives only.

Why it is using only three drives if we are having 16 drives.

Thanks in advance,

  • i just cleaned all drives and refired the backup and had 31 tapes in library.

    then master server used all the drives.

     

    Thanks supporting.

  • I see DOWN drives in tpconfig and vmoprcmd output. That will explain drives not being utilized.

    Again - I cannot see how sharing drives can work correctly without SSO (Shared Storage Option).
