hiho,
if you are using solaris 8 or earlier use Perderabos answere, drvconfig;
if you are using solaris 9 you could use devfsadm
# man devfsadm
DESCRIPTION
devfsadm(1M) maintains the /dev and /devices namespaces. It replaces the previous suite of devfs administration tools including drvconfig(1M), disks(1M), tapes(1M), ports(1M), audlinks(1M), and devlinks(1M).
The default operation is to attempt to load every driver in the system and attach to all possible device instances.
devfsadm then creates device special files in /devices and logical links in /dev.
*The official procedure is to do a reconfiguration reboot.*
sorry, that's not my opinion, solaris is using an full dynamic kernel (that's no bug, that's a feature!) and full reconfigureable processes.
# man path_to_inst
This file is read only at boot time, and is updated by add_drv(1M), devfsadm(1M) and drvconfig(1M)
be happy using an windowless OS... suns big maschines are also able to rebind whole processor boards without an reboot.. Downtime costs money!
greetings Preßy

scsi.ioentry
Fires when SCSI mid layer prepares a SCSI request
Arguments:
disk_major
The major number of the disk
disk_minor
The minor number of the disk
device_state
The current state of the device. The possible values could be:
SDEV_CREATED = 1, /* device created but not added to sysfs
* Only internal commands allowed (for inq) */
SDEV_RUNNING = 2, /* device properly configured
* All commands allowed */
SDEV_CANCEL = 3, /* beginning to delete device
* Only error handler commands allowed */
SDEV_DEL = 4, /* device deleted
* no commands allowed */
SDEV_QUIESCE = 5, /* Device quiescent. No block commands
* will be accepted, only specials (which
* originate in the mid-layer) */
SDEV_OFFLINE = 6, /* Device offlined (by error handling or
* user request */
SDEV_BLOCK = 7, /* Device blocked by scsi lld. No scsi
* commands from user or midlayer should be issued
* to the scsi lld. */
scsi.iodispatching
Fires when the SCSI mid layer dispatches a SCSI command to the low level driver
Arguments:
host_no

Arguments:
host_no
The host number
channel
The channel number
lun
The lun number
dev_id
The scsi device id
device_state
The current state of the device
data_direction
