yes, EMM server automatically will chage this.
2 Scan host and drive owner for Shared drive are same?
if you mean device host, both are different..
3 Scan host is permanent for a drive throughout?
no, it can change...
4 Role of SCAN host?
scans unassigned drives and update the status to EMM server.
1.Rule for changing?
3.Change is for temporary basis?
2.media server which has been assigned the drive and that drive scan host are same?
1.Rule for changing?
A scan host is assigned for a shared drive until some interruption occurs.
For example, if one of the following occurs, EMM chooses a new scan host:
The socket connection, the host, the drive, the drive path, or the network goes down.
The drive is logically placed in the Down mode.
The scan host temporarily changes to hosts that request tape mounts while the mount is in progress. Scan host changes occur so only one host at a time has access to the drive path.
3.Change is for temporary basis?
The scan host temporarily changes to hosts that request tape mounts while the mount is in progress. Scan host changes occur so only one host at a time has access to the drive path
2.media server which has been assigned the drive and that drive scan host are same?
i belive that is not mandatory...

@Nagalla:Many thanks for ur concern.
Just last querry:
When EMM changes the SCAN host,And after the backup completion,SCAN host remains the same?
for Drive LN-DRV05
scan host is LXMC74 and its allocated to LXMC75 for job.
Drive LN-DRV03.
both scan host and allocated to LXMC74
Drive LN-DRV01
is allocated to LXMC78 and the scan host is LXMC72
the allocations chage based on the Drive requests for jobs..
and the scan host are to scan unassign drives.. .its selected by emm server based on avaliablity.
so scan host changes with each job?
The scan host temporarily changes to hosts that request tape mounts while the mount is in progress. Scan host changes occur so only one host at a time has access to the drive path.
this will answer your question. from the like that you posted..
i am just querious... do you have any issue with scan host?
why dont you leave this scan host management to EMM server?
