You may also want to change the "dyntrk" to "yes" on the scsi device. I've changed the "fc_err_recov" (like shockneck suggested) and the dyntrk to yes and I've done a few tests where while writing to the disks, I would unplug one of the cards and the writing would continue, then I would plug it back in about two seconds later, unplug the other and the writing still continued. You can run this command to save the attribute changes to the ODM:

Code:

chdev -l fscsi0 -a dyntrk=yes -a fc_err_recov=fast_fail –P

Then you just need to remove the devices like shockneck said and use cfgmgr to bring them back.
