Hook that, and then check the name server. This will tell you when ports get added/removed. You can then report luns against lun 0 of all the known target ports. This allows you to transparently detect changes. Otherwise, you run the risk of trapping UA's in the lower level portions of the stack that _REALLY_ need to be propagated to the controlling driver or application. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQEcBAEBAgAGBQJRBpOeAAoJEL5i86xrzcy765gH/AnG1TPJ5Y3RGx00TiLP5shb +yS384FoIis4XuWijUdofsAcnZzUFaMgH7lPBr5TkT1yYDgyXtzvpjV/2rvWlvzA PfHPU4vPFmpF1XO7IX2PJCpHAYheHXhucnMkXVLI9GA5nR9+BPQjjvav24ixGKPc b2889zju7Z7KUb0R4SXWtSCbRZZtYuBj0Rckh8a/ra9wJXHuMpsg7+7OzrLqbSqH OcAmcb5Q8T/5D6Rj4rJVF3d1Fzr5+P2qrMhS+eb98I6phZ5UvHs66nY/pHjCGpbA SShQlGOg7+nIjxsf9jjl2/sgx0jJH40koyW8Xv9WERE75eQ9bVBpBX3BeosvlJs= =isBF -----END PGP SIGNATURE----- -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
