SP4-Pool is a rpm-md repository containing all packages from the SP4 media (It does not contain the patches for migration).By default, the catalog is returned as unsubscribed and not added to Ya ST.This tool acts as Novell Customer Center proxy both for client registrations and as software update repository.
Please have a look at TID 7001199 - Which software catalogs to mirror with Subscription Management Tool which explains the different catalogs and which ones that are needed in the various scenarios of installation sources and update paths in more detail.
As an alternative to downloading the updates for each single client system from the Novell update server, it is possible to use Subscription Management Tool for SUSE Linux Enterprise to mirror the updates to a local server.
Perform a system update instead of a fresh installation.
To achive this, select"Installation" - Select "Update" instead of "New Installation".
