Hi Debbie, If your diskpool is big enoufh, you can try a "move nodedata <nodename> from=<tapepool> to=<diskpool>" first, so you can restore from disk. Than you know if the problem is in the library or not.
I also know that Netware is not so fast in building big directory structures, so you can also win alot with dirmc, than TSM restores the directory stucture first, and than the files. If posible you can even use a small diskpool for dirmc's only, what you don't migrate to tape, this is also a big winner when restoring "slow" FS's as Netware and NTFS.

I'm especially interested in this because it took 56 minutes to restore 6.24G of data, from Novell server to Novell server, over a 100MB pipe. Our TSM version is 5.1.1 ( I know,,,we need to upgrade)...and the client version is 5.2. In the dsmserv.opt file the MIRRORWRITE DB = SEQUENTIAL. According to this doc, we'll get better performance is we change MIRRORWRITE DB to PARALLEL. I thought I would do this then add the DBPAGESHADOW = YES parameter. (the MIRRORWRITE LOG = PARALLEL) My plan is to make small changes to see if there is an impact, positive or negative. We have 2G of virtual memory, so I changed the bufpoolsize from 262144 to 524288 and thought I'd make the MIRRORWRITE DB change also. Has anyone made these changes and seen any performance improvements/degredations? Any experiences or advice is welcome..... Thanks for any input, Debbie
