Some things that come to my mind immediately: Positives for minidisks: Much simpler creation of 2nd level test systems -- copy to new volume/mdisk for 2nd level and don't mess up real volsers Much simpler DR -- can be restored to replacement disks w/o relabeling or disturbing existing volume naming scheme. Minidisks are accessible from other userids (dedicated devices are not accessible from other ids) for dumping, etc (cf other ongoing discussion on backups). MDC for minidisks can be trivially re-enabled non-disruptively if you need/want it. Negatives: Lose hardware IOASSIST feature for non-dedicated volumes. Not as important as it used to be, but still noticeable. ---------------------------------------------------------------------- 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
