The TSM Admin guide has the following info which I assume applies to client backups:
Concurrent volume access Disk Volumes: A volume can be accessed concurrently by different operations. File Volumes: Only one operation can access the volume at a time. So it depends on whether you are using device type disk or device type file for your disk volumes. -----Original Message----- From: TSM_User [mailto:[EMAIL PROTECTED] Sent: Wednesday, November 17, 2004 12:49 PM To: [EMAIL PROTECTED] Subject: Re: TSM and SATA Disk Pools Mark, Where did you get the information about "each backup session (remember a client could have multiple session) opens a volume for its exclusive use". I can't find any documentation anywhere to support this. I have heard other AIX admins make the same claim. I have quite few Windows TSM server that I am sure have more client sessions sending data (consumer threads) then I have disk pool volumes. I can't say I've ever run a q sess to see if the number of nodes sessions in a SEND state are greater than the number of volumes I have though.
