Hello, I repackaged Dave Olien's scsi-start hwhandler to try to give it a wider audience. It now compiles out-of-tree, and builds fine on RHEL4U1 kernel. This hwhandler is targeted at a family of assymmetric arrays like HP StorageWorks and FSC FibreCat that take a START_STOP SCSI cmd as a sign of the host willing to initiate a LUN failover. It would be good to have this code undusted and endorsed by HP ... before RHEL4U2 freezes. Seems a good topic for the next conf call :/ You can find the tarball there : http://christophe.varoqui.free.fr/multipath-tools/dm-scsi-start.tar.gz Regards, cvaroqui
