add the following (there are 6 significant spaces between the first occurrences of HP and Ultrium
in line 2):
tape-config-list =
"HP Ultrium 5","HP Ultrium LTO 5","HP_LTO_GEN_5";
HP_LTO_GEN_5 = 2,0x3B,0,0x18659,4,0x00,0x44,0x46,0x58,3,60,
1200,600,1200,600,600,18000
name="st" class="scsi" target=
X lun=0;
where
X
is the SCSI target address

of the device you have attached.
See “ HP-data values ” on page 28 for the values of the parameters in these lines.
2. Instead of rebooting the device, follow these steps.
a. Find the kernel module ID:
# modinfo | grep "st ("
96 60dcc000 cdb0 33 1 st (SCSI Sequential Access Driver)
In this example the ID is 96.
b. Unload the kernel module:
# modunload -i 96
c. Load the kernel module back in:
# modload -p drv/st
d. Rebuild the device paths:
devfsadm -C
devfsadm -i st

Typically
st.conf
already contains a range of target address entries by default, listed after the comments section (
#
prefixes)
in the above format:
name="st" class="scsi" target=X lun=0;
While SAS drives contain a unique 64-bit SAS
address, they are also allocated a target address value in the operating system. To obtain a particular tape drive’s target
address, run the following command to identify it:
% ls -l <tape device file>
This produces a line of output which includes a path which in turn contains an
st@ X
element, where
X
is the target address.
For example:
% ls -l /dev/rmt/0cbn
would produce output containing something like the following path:
/dev/rmt/0cbn -> ../../devices/pci@0/pci@0/pci@8/pci@0/pci@8/pci@0/pci1077,14f@1,1/st@3,0:cbn
The element
st@3
here indicates target address = 3.
