I appear to have resolved my problems.
This may not be the best solution, but it does seem to work.
Solution:
On VM Host, "server1" (CentOS 4.4):
- add to "/etc/rc.d/rc.local":
- "modprobe sg" so sg0 is found at boot; resolves problems with sg driver
not loading at boot for some reason
- "MAKEDEV -v sga" for VMware guest to connect to sg0, this creates sga as
a link to sg0
- in "/etc/udev/permissions.d/50-udev.permissions"
- the VMware guest "bacula1" could not access the tape drive with the
default permissions on sg0, so under "# scsi devices", set permissions for sg*
as 0666 instead of 0660: "sg*:root:disk:0666"
On VM guest "bacula1" (CentOS 4.4):
- add to "/etc/rc.d/rc.local":
- "modprobe sg" so "/dev/sg0" and "/dev/sg1" are created at boot (sg0 is
the virtual hard drive); resolves problems with sg driver not loading at boot
for some reason
Bacula (from rpm for RHEL 4, bacula-postgresql-1.38.11-3):
- changes to bacula services (daemons):
- "/etc/rc.d/init.d/bacula-sd": default is "bacula:disk", changed to
"root:disk", otherwise Bacula autochanger features would not work

>> Then, I found the documentation section, "Autochanger Errors", that showed

>> My _guess_ at this point is that it's either:
>> 1) something to do with the the number of command paramters

>> Any insight or suggestions would be greatly appreciated.
