When defining an OSE connection, firstly you need to determine which type of OSA card you need for your configuration. ODE connections use use the copper-based OSA Express7S 1000BASE-T card: 

GLYPH<SM590000> Optical based cards: 

– OSA Express6S GbE SX or LX 

– OSA Express6S 10 Gb SR or LR 

GLYPH<SM590000> Copper-based cards: 

– OSA Express6S 1000BASE-T 

The following are considerations for a new OSE CHPID: 

GLYPH<SM590000> Channel path ID (CHPID) 

GLYPH<SM590000> Channel ID (CHID) 

GLYPH<SM590000> Channel path type 

GLYPH<SM590000> Operational mode 

GLYPH<SM590000> Description 

GLYPH<SM590000> Partition access list 

GLYPH<SM590000> For performance and redundancy, how many I/O cards of that feature are installed in the processor and to what PCIe ports on what CPC drawer do the I/O cards connect to (see the PCHID/CHID report for a list of installed hardware) 

To define a new OSE CHPID, and provide access to a partition, complete these steps: 

1. From the main HCD panel, select option 1.3. Processors .
