Do you have these attributes set on your fscsi devices on your VIO servers?
Code:
vio2:/home/padmin:# lsattr -El fscsi0 | egrep "fc_err_recov|dyntrk"
dyntrk       yes       Dynamic Tracking of FC Devices        True
fc_err_recov fast_fail FC Fabric Event Error RECOVERY Policy True
vio2:/home/padmin:#

I also set these attributes on the disks themselves on the VIO servers:
Code:
vio2:/home/padmin:# lsattr -El hdisk5 | egrep "rw_timeout|q_type"
q_type          simple                           Queue TYPE                       True
rw_timeout      30                               READ/WRITE time out              True
vio2:/home/padmin:#

To be honest, I can't remember what they do, but I'm sure I had a good reason to set them this way when I first configured them.
