This feature is new in the Software Express pilot program. This feature is included in the Solaris 10 3/05 release.
The Solaris SCSI disk driver now supports SCSI logical unit reset. This feature improves error recovery processing on multi-LUN SCSI target devices. This feature can reset a logical unit without affecting other logical units on that device.
The ability to reset LUNs is particularly useful in conjunction with multiple pathing and with storage units that provide a large number of LUNs. For more information, see the scsi_reset(9F) and the tran_reset(9E) man pages.
