Re: [Veritas-bu] New tape drives not appearing in /dev/rmt.

Next time try doing a `cfgadm -al`.  You'll probably see the tape device
as unconfigured.  do a `cfgadm -c unconfigure cX` (cX is the
channel...it's the left hand collumn in `cfgamd -al` such as c6 or c5,
etc...) and then a `cfgadm -c configure cX`  That's worked for me in the
past.  You'll also need to make sure that your sg.conf file has the
correct targets and luns defined in it....when you do your `sg.build all
-mt X -ml X`

A solution that worked, and suggested by a Veritas-bu subscriber, was to
manually add the tape drives to st.conf and reload the driver.  This
successfully generated the missing /dev/rmt entries and allowed me to
proceed with the robot and drive configuration using tpconfig.

Steps:

Added entries to /kernel/drv/st.conf:
name="st" parent="fp" target=0 lun=0 fc-port-wwn="500308c00189780a";
name="st" parent="fp" target=0 lun=1 fc-port-wwn="500308c00189780a";
name="st" parent="fp" target=0 lun=2 fc-port-wwn="500308c00189780a";
name="st" parent="fp" target=0 lun=3 fc-port-wwn="500308c00189780a";
name="st" parent="fp" target=0 lun=4 fc-port-wwn="500308c00189780a";
name="st" parent="fp" target=0 lun=0 fc-port-wwn="500308c00189780b";
name="st" parent="fp" target=0 lun=1 fc-port-wwn="500308c00189780b";
name="st" parent="fp" target=0 lun=2 fc-port-wwn="500308c00189780b";
name="st" parent="fp" target=0 lun=3 fc-port-wwn="500308c00189780b";
name="st" parent="fp" target=0 lun=4 fc-port-wwn="500308c00189780b";

Determine st driver Id and display details:
modinfo | grep st
...

modinfo -i 49
 Id Loadaddr   Size Info Rev Module Name
 49 786e0000  132e4  33   1  st (SCSI tape Driver 1.221)

Reloaded st driver:
modunload -i 49

modinfo -i 49
can't get module information: Invalid argument

devfsadm -i st

tpconfig work.

Backups now working fine to the new tape drives.

Adding the entry to st.conf followed by a boot -r did NOT fix my
problem.  The missing /dev/rmt entries are still missing.

I've opened another issue with SUN.

The original six drvies in the L700 are still there and usable.

The new four drives in the Scalar i2000 do not exist in /dev/rmt, yet
are shown in cfgadm.

SUN's response is that my st.conf is missing:

name="st" parent="fp" target=0;

>>From looking at old files, this line was probably removed by mistake in
2005 during another drive configuration, and obviously is not needed for
the existing L700 and 9840 drives which are working fine.

Now to find time and get permission to boot the production server...
