We are new to running zVM 5.4 and have Red Hat zLinux as guest machines. We are using OSA Express 3. Two OSAs on different chpids and on differen t NIC addresses. We separated the two OSA because we want the primary OSA
to be used only for production traffic and the secondary OSA for Netbacku p backup traffic only. However when we perform the Netbackup backup of files, the primary OSA slows down or stalls until the backup traffic completes on the secondary OSA. I heard that there may be a bug that is causing one OSA disabled while th e other OSA is enabled and active? Possibly with OSA Express 3 and TCP Layer 2? I searched the IBM knowledge base and could not find a match or locate a fix. I am holding off on opening a issue with IBM for now, but will soon if I can't find anyone having or have run into the same issue. Any help would be appreciated. Thanks, Steve.
