We have migrated a significant portion of our Linux disk space to FCP connections, and have been very pleased with the performance and with the ease of setting up very large file systems. I would note a few cautions: 1.We found that setting up FCP disk for the first time had a fairly formidable learning curve. The mail I see on this list suggests that our experience is not unusual. 2.We still have disks we have left on ECKD devices because our current hot site contract does not include FCP disk for the mainframe. Make sure your disaster recovery process can supply FCP disks, or that you can convert back to ECKD at the recovery site in an acceptable amount of time. 3.We have never tried to use an FCP disk as a boot device. I gather that the internals of the FCP boot process are considerably different than the internals of the traditonal mainframe boot process. I don't know how diffictult it is to set up the newboot process. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
