OK, I can do that. Does this mean you think it is a better solution to migrate
over the network using virtual volumes? If so, is ADSM3.1 and TSM4 compatible
regarding virtual volumes?

Can you just migrate the clients and leave the data until it is not needed?


No, most of the data needs to be migrated. 1TB is archived data and I'm not
happy about expiring the 3TB backuped data (perhaps expiring half of it would
be acceptable), also both the old server and old library will be sold within
weeks.

        Subject:        Migrating to a 3466 C01

        We currently run ADSM server 3.1.2.90 on a IBM F40 with an ACIC
Scalar 1000
        DLT-7000 library, and are planning to migrate to TSM 4 on an IBM
3466-C01 with
        an IBM 3584 LTO library.

        Normally we configure and install our server HW/SW ourselves, but as
I
        understand
        it the 3466 comes pretty much preinstalled (or at least is installed
on site by
        the vendor) and I don't want to void the warranty and service
agreement.

        Usually when we change server HW we just move the disks to the new
system, but
        now we have SCSI disks on the F40 and SSA disks on the 3466. As I
see it there
        are two ways of doing this migration:

        1. Install ADSM 3.1 on the 3466 and move the db by backup/restore,
devconfig,
        volhist etc, and also attach the Scalar 1000, to the 3466 (we have
DRM on the
        3.1 license so perhaps we could use this to make things easier).
Upgrade to
        TSM 4
        and then migrate the data by move data or stgpool migration. Only
concern here
        is if the installation guys will approve.

        2. Using virtual volumes perform export/import server and also
stgpool
        migration
        over the network.

        We currently have about 4TB in the primary tape stgpools and the F40
has a
        100Mbit/s
        ethernet adapter so of course the network will be the bottleneck
using
        method 2.

        Anyone has experience on migrating to a 3466?
