Firstly, what type of device hardware are you using? If it is an LTO drive then try this
Configuring the LTO tape drives.
1) SOLARIS Setup:
=================
On Solaris the default tape drive driver is st and it provides the interface to
various SCSI drives which may or may not be Sun supported. st has a built in
table for all Sun supported devices and for others the device information can
be provided in st.conf file as global properties illustrated below. For the
st.conf changes to take effect we need to remove the old handles in /dev/rmt
directory followed by a reboot with "boot -r". We can also do run drvconfig
followed by tapes to recreate the handles after they have been removed in case
a reboot is not feasible.
To use the LTO drive with the st driver we should have the following st.conf
entries:
tape-config-list=
"IBM ULTRIUM", "IBM Ultrium", "LTO_Ultrium",
"IBM ULTRIUM-TD1", "IBM Ultrium", "LTO_Ultrium",
"IBM ULT3580-", "IBM Ultrium", "LTO_Ultrium",
"IBM ULT3580-TD1", "IBM Ultrium", "LTO_Ultrium",
"SEAGATE ULTRIUM06242-XXX", "Seagate LTO", "LTO_Ultrium",
"HP Ultrium", "HP Ultrium", "LTO_Ultrium",
LTO_Ultrium = 1,0x36,0,0xd639,4,0x00,0x00,0x00,0x40,3;
Suggesting that the 'l','m', and 'h' devices are identical non-compression and
the 'u' and 'c' device is compression.
# cd /dev/rmt
# rm *
# drvconfig -i st
# tapes
# /etc/LGTOuscsi/inquire
an example output is :
scsidev@5.1.0:IBM ULT3580-TD1 0BN1|Tape, /dev/rmt/0cbn
csidev@5.6.0:IBM ULT3583-TL 2.00|Autochanger (Jukebox)
LTO support in Solaris 8 requires patch 108725-08 (st driver patch). In addition
to st driver LTO drives are supported by IBM atape driver as well. More info is
available from ftp://ftp.software.ibm.com/storage/devdrvr/Solaris
TAR to the tape to erase the existing NetWorker label.
Verify the tape label writes at 64KB through the nwadmin GUI.
