Another question on same issue, let me know if you can help. When I try to 'MAP' the FBA disk using the 'ZFCP' module this is what I get :
LNOUC4D:~ # insmod zfcp map="0x0406 0x01:0x50060482ccb539c8 0x0:0x0107000000000000" insmod: can't read 'zfcp': No such file or directory LNOUC4D:~ # Can see what I am missing !

There is only the one driver: DASD, with varying sub-components. Also, some commands will not work with an FBA disk, notably 'dasdfmt' and 'fdasd'. While 'fdisk' does work, last time I used it there was some confusion in its logic when run against FBA. Note that FBA does not require the low-level format function of 'dasdfmt'. It is already blocked. No shame in using /dev/dasdd as un-partitioned! If it is to be LVM fodder, that makes all the more sense. But if you abso-blasto-lutely must partition it, then CP LINK the EDEV to CMS and FORMAT it there. You'll then automagically get "LDL" (zLinux disk layout) instead of "CDL" (compatible disk layout, which requires CKD). CMS FORMAT will skip the block creation on FBA disks and simply lay a CMS filesystem onto the disk. Linux will see that and do its own thing, resulting in LDL with one (and only one) partition, /dev/dasdd1. -- R, Michael Harvey <[EMAIL PROTECTED]> Sent by: Linux on 390 Port <LINUX-390@VM.MARIST.EDU> 08/07/2006 10:06 AM Please respond to Linux on 390 Port <LINUX-390@VM.MARIST.EDU> From Michael Harvey <[EMAIL PROTECTED]> To LINUX-390@VM.MARIST.EDU cc Subject ECKD vs FBA problem on MF Linux Lpar We have the Linux Lpar under ZVm and connected thru a McData Switch. We see the following on device eg. 406 as FBA but later is seen as ECKD device. What informational source can I use to do a step by step allocation of FBA devices or understnd more on this topic.
