Identifying I/O device requirements

z/OS® supports Fiber Connection (FICON®), Enterprise Systems Connection (ESCON), and Enterprise Systems Architecture/390 (ESA/390) devices. Table 1 lists the most commonly-used I/O devices that are supported by z/OS. If you have a question about support for a device not listed, contact your IBM® representative.

Note: The table does not comprise a list of devices that are service supported. Many of the devices have been withdrawn from service support. Rather, the table comprises a list of devices that are supported by the software (z/OS). Normally, when devices are withdrawn from service, they continue to be supported by the software. DASD devices attached to some older controllers, such as a 3880, 3990-1, or 3990-2, can still be defined in Hardware Configuration Definition (HCD), but these devices cannot be varied online to a z/OS V2R2 system.

Use of the IBM TotalStorage Enterprise Storage Server® (2105) with z/OS requires the 2105 microcode to be at EC fix level F25584 or later. This EC level fixes a problem caused by software exploitation of the SII/RND CCW commands.

For a table summary of device information, see z/OS MVS Device Validation Support. The table shows the order that z/OS uses when it attempts to satisfy a request for a device.
