HP LTO Ultrium 5 tape drives UNIX, Linux and OpenVMS configuration guide (March 2010)

1. In the file /kernel/drv/st.conf, after these lines:

########

# Use is subject to license terms.

#pragma ident "@(#)st.conf 1.34 04/06/24 SMI"

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.
