Drive Scan host not active

Hello ,

we are facing above problem in our environment. When we up one drive on any media server , we are getting drive scan host is not active error.This error is getting almost all media servers , which we tried to up the drive.

 

Master Server : Solaris 10

NBU : 7.5.0.6

 

Media servers : AiX/Wndows

 

Please Suggest.

  • Nothing short term.

    You firstly need to cut down on number of media servers or stand up another master server.
    Symantec's recommendation is a maximum of 100 media servers (although there is no physical limit).

    Then you need to carefully calculate number of device entries in the emm database. This includes media servers, tape drives, storage servers, disk pools, storage units.
    For example, 100 media servers sharing 50 tape drives will result in 500 emm device entries. That is without stu's and entries for the media servers itself.
    Recommendation is to not exceed 1500 device entries in emm.

    There was a best practise and performance tuning session at Vision this morning, presented by Symantec lead architects. As soon as the pdf version of the presentation is posted on Connect, I will post a link.
