Another approach to avoid this issue is make this an auto-take diskset. One can do that by
metaset -s my_set -A enable. This automatically prevents SVM from issuing SCSI-2 reservations. Note that you can only have a single host as the owner of the diskset. I am assuming here that you are using disksets to aggragate drives. I am not aware of a "multi-initiator", SATA protocol. -Sanjay Tony Nguyen wrote: > SCSI reservation prevents drives in SVM disksets to be used for other > purposes.
