OSA-ICC 1GE Fiber Cards need to support VLAN TAGGING in the ICC Server Configuration Panels

IBM is discontinuing the Copper based OSA that support OSA-ICC consoles. The only available OSA-ICC cards in the future will be FIBER based 1GE cards. In our environment all of our FIBER switches require VLAN tagging. This IDEA is to support a VLA...

Add VLAN tagging capability to OSA ICC in the advanced facilities configuration - z feature code 0455

The OSA 1GE cards do support VLAN tagging .. but the OSA-ICC “appliance” does not support VLAN tagging. UPS is requesting that VLAN Tagging support be added to the Advanced Facilities configuration option for the OSA-ICC server

DS8950F TCT Monomode Fiber connection

We need to create a cross infrastructure at a distance not supported by multimode fiber. The availability of single-mode 10Gb cards is therefore required

z13 FICON path selection

a z/13 CPU design issue. An IO subsystem algorithm checks path activity and if one becomes less active it swings processing to the remaining normally efficient path. However, it never rechecks the poorer performing path to allow it to return to th...

Request to Add Full dynamic Activate support in SACF Lpar on Z14 and above

Reference case: TS003931886When there are no requirements for a ZOS LPAR or ZVM LPAR, there is still a need to configure resources beyond coupling facility. The SACF Activation LPAR needs to be able to handle equivalent of the Dynamic Activate fun...

Dynamic HW activation support for LinuxONE III

JPMC has purchased three LinuxONE III machines to use for IDAA SSC. This will be part of their zOS IODF. They have asked if they would be able to perform dynamic activations on this machine like they could for their standalone coupling facilities.

Offline BER test on FICON channels

On IBM DS8K products we are able to perform an offline Bit ERror (BER) test to check a FICON link's quality while the path is offline but the cables are connected. My understanding is that this is accomplished by using idle characters being sent o...
