Is the node's active data spread out across all the tapes? Ie. Is the restore actually using all of the tapes?
Note that TSM does not do a multi-session restore for data on devtype=disk (it can have one coming from disk and others from tape). You must be doing a NQR to use multi-session restore (which you probably are!) -----Original Message----- From: Wheelock, Michael D [mailto:[EMAIL PROTECTED] Sent: Monday, February 14, 2005 12:28 PM To: ADSM-L@VM.MARIST.EDU Subject: AIX Restore Hi, I have a restore that we do occasionally to create a test environment for one of our applications. The storage pool for this restore is a tape based storage pool with collocation set to no. Consequently, there are lots of tape mounts done to effect this restore. To alleviate this at least in part, we have set the resourceutilization parameter on the client and the maximum mount points allowed to 6. This should theoretically allow the client to open six sessions and go about its business. In reality, it is about 50/50. Half of the time it will open multiple streams, half the time it will not. There are always free tape drives on the TSM server. There are always two filesystems being restored over multiple (>10) tapes. Here are the various version info: TSM Server: AIX 5.2 ML4 TSM 5.3.0.0 (though the same was seen on 5.2.3.4) Client: AIX 5.2 ML4 TSM Client 5.2 When we opened a support call, the only answer provided was that in the cases where we saw multiple streams, the data must have been flowing from a disk storage pool. I accept that, but I believe that I would never see these process (sessions) go into mediaw status (fyi, we currently only have disk class disk storage pools ahead of these tape ones...no file class storage pools). TSM should know where the data is (ie. On multiple tapes) and allow the client to open the multiple streams to increase the throughput. Any ideas why I am seeing what I am seeing?
