and weekly IPLs.
Why weekly ipls? One of the big advantages of mainframe technology is that
ipls are (should be) infrequent
If your TSM is in a sharing lpar the TSM dispatching priority can be set so
Hi all
One best difference of TSM running on OS/390 or Z/OS is that his cpu
hungry. Use WLM giving a fraction number of SRU service units and all will
be good.

I know I have seen other messages about this before, so I hope I can find some info.
We are looking into migrating our TSM servers off of Z-OS and I would like to know if
any one else has done this and if they have useful tips and maybe even a high level
document of the process?
Thanks!
Hi Ryan,
I am at the tail end of a conversion from OS/390 to solaris. I don't have
a document to share with you. One nice thing that helped a lot is to do an
export server filed=none to a disk file on OS/390, FTP it using bin to the UNIX box.
On the UNIX box define a devicetype to see the
Were your libraries and tape drives managed by CA1 on the mainframe, if so, could the
same volumes be recognized by the new media manager on UNIX. My fear is having to
convert or move 270 TB of data already on tape. Or did you not move any data from the
OS/390 side and just start with fresh
We didn't move any backups, we did fresh backups
but I will move archives using the server to server export
feature in 5.??.
The old server had just 20T of data.
Our tapes, 9840's, were not managed by ca1 or any other tape mgmt software. I defined
tapes
explicitly to tsm. We are a small

Thanks for the info. It looks like we may have an interesting time ahead for us. If
ex/import is the only way to go I'm not sure if even the incremental ex/import
feature, if IBM ever comes out with it, will help us. Leaving the data behind is not
feasible, we need to have 24 hour
Ryan,
IBM does have incremental server to server export at the 5202 server level. It came in
below that but I am not sure where. Of course you can only use it after you have
exported the
current 270T, which is a long time from now.
Just because you do backups to a new server, you don't have
We are still at 5.1.6.1, next upgrade scheduled for 2Q04, so I guess I will have it
then. I could use it to accomplish this migration, but I think it would be lengthy
process, considering I can probably move around 1 - 2 TB daily.
The idea of moving off of OS/390 is because we are taking too
