.Dd February 22, 2000 .Dt SES 4 .Os .Sh NAME .Nm ses .Nd SCSI Environmental Services Driver .Sh SYNOPSIS .Cd ses* at scsibus? target ? lun ? .Sh DESCRIPTION The .Nm driver provides support for all .Tn SCSI devices of the environmental services class that are attached to the system through a supported .Tn SCSI Host Adapter, as well as emulated support for SAF-TE (SCSI Accessible Fault Tolerant Enclosures). The environmental services class generally are enclosure devices that provide environmental information such as number of power supplies (and state), temperature, device slots, and so on.
p A .Tn SCSI Host adapter must also be separately configured into the system before a .Tn SCSI Environmental Services device can be configured. .Sh IOCTLS The following .Xr ioctl 2 calls apply to SES devices. They are defined in the header file .Aq Pa scsi/ses.h (q.v.).
p l -tag -width SESIOC_GETENCSTAT t Dv SESIOC_GETNOBJ Used to find out how many SES objects are driven by this particular device instance. t Dv SESIOC_GETOBJMAP Read, from the kernel, an array of SES objects which contains the object identifier, which subenclosure it is in, and the SES type of the object. t Dv SESIOC_GETENCSTAT Get the overall enclosure status. t Dv SESIOC_SETENCSTAT Set the overall enclosure status. t Dv SESIOC_GETOBJSTAT Get the status of a particular object. t Dv SESIOC_SETOBJSTAT Set the status of a particular object. t Dv SESIOC_GETTEXT Get the associated help text for an object (not yet implemented). SES devices often have descriptive text for an object which can tell you things like location (e.g., "left power supply"). t Dv SESIOC_INIT Initialize the enclosure. .El .Sh FILES l -tag -width /dev/rsdXXXXX -compact t Pa /dev/ses Ns Ar N The Nth SES device. .Sh DIAGNOSTICS When the kernel is configured with .Tn DEBUG enabled, the first open to an SES device will spit out overall enclosure parameters to the console. .El .Sh SEE ALSO .Xr getencstat 8 , .Xr sesd 8 , .Xr setencstat 8 , .Xr setobjstat 8 .Sh HISTORY The .Nm driver was written for the .Tn SCSI subsystem by Matthew Jacob. This is the functional equivalent of a similar driver available in Solaris, Release 7.
