New AIX61 install, rootvg is on local SAS. All data drives are on SVC. I installed the sdd script and the sdd device driver. I configured vdisks, and added them one at a time to host; running cfgmgr shows 8 hdisks (expected, since I have two dual-port hba's; I intended to have eight paths to every vdisk).
datapath query device shows eight hdisks belonging to vpath0 (again, expected). However, when I reboot server, the original hdisks went defined, and 8 new hdisk definitions showed as available, and datapath query device shows the 'new' hdisks now belong to vpath0.
SDD and AIX appear to be doing what they're supposed to, and I can create vg-lv-file systems on vpath0, and I can access file systems on vpath0, but I can't account for the 'new' hdisk definitions; I apparently missed a step somewhere, but can't figure out where.
I made some 'changes' to the fscsi protocol devices per SVC Best Practices and Performance Guidelines redbook to allow for fast_fail and dyntrk=yes
Has anyone else experienced this behavior and resolved it? Have I missed a step somewhere?
