System can see the disk(LUN),create partition and mount. even create folder on it. but when you copy many and large file to it, it report many io errors. if you stress the i/o, system will hang. Here is the link about BCS http://www-03.ibm.com/systems/bladecenter/hardware/chassis/blades/index.html. BCS has a Disk storage module and a RSSM in i/o bay 3and 4. It a SAN based on SAS connection. >How-To-Repeat: install freebsd and copy file to external disk >Fix: >Release-Note: >Audit-Trail: >Unformatted:
