Hi Lee, The biggest EDEV you can have is 1TB minus one page, with some exceptions depending on the application of the EDEV:
DRCT, PAGE, SPOL allocations must reside in the first 64GB (minus one page) of the volume CMS volumes are technically limited to 381GB, but will be less than that in practice More explanations can be found in Chapter 22 of the CP Planning and Administration manual. http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/HCSG0B30/4.5.1?DT=20081120142224 Regards, Eric Eric Farman z/VM I/O Development IBM Endicott, NY From: Lee Stewart <[email protected]> To: [email protected] Date: 01/27/2009 07:50 PM Subject: Max EDEV size? I've looked, and maybe overlooked, but is there a maximum size for an EDEV? LUNs on a SAN can be pretty big... Anyone know if it's documented anywhere?
