OSA/SF and Device Configuration
Pre-Config thoughts:
- Each OSA2 port should either be connected to the network or have the wrap plug installed (IE: the port needs to be terminated somehow...otherwise data bits may leak out!).
- In order for the OSA2 card to work, it needs to have a TCP/IP Image and/or an SNA Image applied to the card. All OSA2 cards (except the ATM type) come with the TCP/IP Image already applied.
General Thoughts:
Neither OSA/SF and/or OSA2 modifications are needed if you will be running in default TCP/IP mode only and using default unit/port addresses. However, you will not be able to talk, look, apply service, modify configuration, or basically do anything with your OSA2 card(s) (other than use) until you install OSA/SF.
Configuring your devices:
The basic steps to configure and use devices with the OSA2 card(s)
are:
(Click on hypertext for details and samples)
- Define the device(s) to the system
(IOCDS)
- Don't forget the OSA/SF Unit Address x'FE OSAD definition
- Update the OSA2
OAT table
- GET_OAT and update to reflect your device addresses and uses.
- Osa Address Table - used to define devices to the OSA2 card.
- Issue IOACMD and select the option for -
Config_OSA
- If using a SNA port, the CONFIG_OSA command will note this from the OAT Table and place a SNA IMAGE out to the OSA2 card.
- IOACMD CONFIG_OSA can also be issued to skip the first menu.
- NOTE: If the Config OSA option is not present, you are missing OSA/SF COR APAR OW33394
- Now you will need to
Activate
the OAT and IMAGE file(s) on the OSA2 card
- For Any changes to take affect, you must vary associated devices and the OSA2 CHPID offline (from ALL LPARs/Systems where defined) and online .
- Your OSA2 card should now be ready to operate in the defined TCP/IP and/or SNA mode(s). You now need to attach the devices to the Virtual Machine(s) that will be using them.
NOTE:
- When using TCP/IP, the IOCDS device addresses must match with the OSA2 device address which must match with the TCP/IP Profile Address (Device/Address and Link/Port numbers must match).
- When using SNA connections, ensure the VTAM COR is current so comminications with the OSA2 are understood. Incidents have been reported when ACTIVATEing the OSA2 device from VTAM and receiveing a response of 081C000C or an 081C0000. The 081C000C indicates missing VTAM COR (VM59237 for starters) while the 081C0000 may indicate the OSA2 SNA Image is not activated.
