The st driver needs to be reloaded. Try

# modinfo | grep SCSI
 22 fffffffffbaf6898  14db0 174   1  scsi_vhci (SCSI VHCI Driver 1.46)
 23 fffffffffbb0aa18   fc18   -   1  scsi (SCSI Bus Utility Routines)
 89 fffffffff5a76000  2f510   9   1  iscsi (Sun iSCSI Initiator v20070116-0)
173 fffffffff5e4d000  23390  32   1  sd (SCSI Disk Driver 1.505)
186 fffffffff5ead000  11870 129   1  st (SCSI tape Driver 1.243)
187 fffffffffba81f50   4a80 145   1  sgen (SCSI generic driver 1.10)
201 fffffffff5c45000   5eb0 194   1  ses (SCSI Enclosure Services Driver )

and look for st (5th line in the example above). Unload the driver with
# modunload -i <module id>
The module id is the first column. e.g. in the above,
# modunload -i 186
Next time you open a tape device the driver will be reloaded and will pick
up the new settings from st.conf.

This will only work if the module is idle, so you will need to close all
SCSI tape devices first, which will certainly involve shutting down the
Bacula SD.

If you cannot get modunload to work, a reboot will be the only other way.

Before you reload/reboot, run the mt config command and compare the
settings to the ones you just added to st.conf.

Is it sparc or x86? I believe there is a Solaris/sparc VXA Tool
available from Exabyte.
