If for some reason you cannot upgrade to the minimum patch level, you can make the following file
modifications to enhance performance:
1.
In the file /kernel/drv/st.conf, after these lines:
########
# Copyright (c) 1992, by
Sun Mi crosystem s, Inc.
#ident
"@(#)st .conf
1.6
9 3/05/03 S MI"
add the following depending on which version of operating system you are installing (there are
6 significant spaces between HP and Ultrium in line 2):
for Solaris 8 without st patch:
tape-co nfig-lis t =
"HP Ultri um 3","HP Ultrium LTO 3","H P_LTO_GEN _3";
HP_LTO _GEN_3 = 1,0x36, 0,0xd639, 4,0x44,0x 44,0x44,0 x44,3;
name="s t" class ="scsi"
target= X l un=0;
where X is the SCSI target address of the device you have attached.
for Solaris 9 and 10 (and 8 with st patch):
tape-co nfig-lis t =
"HP Ultri um 3","HP Ultrium LTO 3","H P_LTO_GEN _3";
HP_LTO _GEN_3 = 2,0x3B, 0,0x18659 ,4,0x44,0 x44,0x44, 0x44,3,60 ,1200,
600,120 0,600,60 0,18000;
name="s t" class ="scsi"
target= X l un=0;
where X is the SCSI target address of the device you have attached.
See
below for the values of the parameters in these lines.
2.
If you are replacing an existing tape device on the same SCSI ID, remove the contents of the
/dev/rmt
directory as follows:
% cd /d ev/rmt
% rm *
3.
Do a reconfigure boot:
% cd /
% touch /recon figure
% sync; halt
4.
When the system is down, reboot:
% boot -r
Make sure you include the -r switch, so that the device directory is reconfigured using the new
data.
5.
You should now be able to use the drive.
• Use /dev/rmt/Xcb if you require a compression rewind device file, where X is the relevant
device address.
• Use /dev/rmt/Xcbn when you require a compression non-rewind device.
Once the device files have been created, you should confirm that your new tape drive is working
properly.
