How to find what volumes are assigned to a unit name

Hi,

Is there any rexx routine or mainframe TSO command or menu to check what UNIT names exist on system and what volumes are assigned to it?

The is no simple command to display this. The unit names could be defined in SMS, in which case you need access to the source code for your ACS routines.

Or they could be defined in the Esoteric Device Table in which case you need access to HCD.

In both cases, I would suggest you check with your site support group.

you must find ACTIVE IODF DATA SET whit this command:
D IOS,CONFIG
something like this : SYS1.IODF00
then go to first ISPF menu then go to HC panel (if you have enough permission)
in this panel write active IODF file name and select option 1
every thing you need is here

another way run TSO MXI and type DASD
but only show online unit

There's also different unit groups such as GENERIC (e.g. 3390, 3590 etc), and ESOTERIC (local names, like DASD or TAPE), and quite often units can be in more than one.

HCD is probably the safest option.
