I have 2 new DCX directors (version 6.3.1a), which I just began connecting to disks and hosts (IBM DS8700, HDS USPV, IBM SVC, SAN Router). We just began giving disk space to AIX 6.1 TL01 (from the IBM SVC and HDS USP-V), a Bussiness Object and Informatica repository (a heavy user). We just experinced disk errors and unaccessible disks and crash (in that order) twice after Enable Config was done on the directors. I don't see any errors on the directors. We upgraded before to this verison after IBM told us because of the IBM SVC.
Do anybody knows of some recent bugs in Fabric OS or IBM SVC microcode ?
