The following Redbooks might also be a place to start. The publish dates on the books vary a bit. Also as mentioned there are several lists you can sign up for.

Generally: 1. Learn a bit of Linux concepts. 2. Install Linux on... a) bare LPAR (IMHO the easiest, but not popular) b) under z/VM - that require z/VM and z/VM knowledge. 3. DASD a) You can choose "regular" CKD disk volumes - FICON, HCD, etc. Quite familiar. b) Or you can use FBA devices - FCP channels, new things to learn in HCD/IODF world. 4. OSA a) it is easier and more flexible to use z/VM facilities b) assign some OSA chpid for Linux (not shared with other systems) c) share OSA chpid - IMHO the most demanding. 5. Keep in mind most Linux specialists do not know mainframe HW, so mainframe-specific questions have to be asked to proper forum. IMHO this is the forum (not the only one), despite most of topics are about z/OS. 6. Installation is quite different. No tapes. No driving system. The beginning is similar to z/VM installation process - I mean IPL from ftp server (instead of COD driving system) and the server as installation medium (instead of tapes).
