Names of Add-on I/O Adapters and Consoles  



OpenVMS Version 6.2 and higher supports various add-on I/O adapters and consoles. HP's AlphaGeneration platforms typically support one or more integral SCSI or network adapters, with the option of installing additional adapters. Because of differences in device-naming conventions used by the Alpha console and OpenVMS, depending on the platform, the OpenVMS device name might not match the name the console displays.

For example, on platforms prior to the EV6 systems (except the GS AlphaServer 140), the console designation for a SCSI device on the integral SCSI adapter might be DKA100. However, when two additional add-on SCSI adapters are added, the A designation becomes C, and DKA100 appears as DKC100 when OpenVMS is running.

This discrepancy in device naming does not exist on EV6 and higher platforms.

Note that even when the console and OpenVMS device names are different, the unique specification of a device name from the console to the device name under OpenVMS stays the same, provided add-on SCSI or network adapters are not added or removed.
