HP support was pretty much worthless when STK and I were asking

and the tech manuals for the drives.

Can you post what you came up with for an HP LTO-3 stinit.def entry?  I
didn't make any modifications to the file for our drives, so I'm curious
what you needed that I'm missing.

You're probably not missing anything, at least anything important.
I've included what we originally got from SUN/Stk in the comment.



# LTO Generation 3

# TVM: here's what Sun/STK recommended:
#
# manufacturer=HP model="Ultrium 3-SCSI" {
# can-bsr scsi2logical drive-buffering auto-lock
# timeout=800
# long-timeout=14400
# mode=1
# blocksize=0
# density=0x00
# fast-eom=1
# }

manufacturer="HP" model = "Ultrium 3-SCSI" {
        scsi2logical=1
        can-bsr=1
        auto-lock=0
        two-fms=0
        drive-buffering=1
        buffer-writes
        read-ahead=1
        async-writes=1
        can-partitions=0
        fast-eom=1

        #
        # If your stinit supports the timeouts:
        timeout=3600            # 1 hour
        long-timeout=14400      # 4 hours

        # 400 GB + compression
        mode1 blocksize=0 density=0x44 compression=1

        # 400 GB, no compression
        mode2 blocksize=0 density=0x44 compression=0

        # LTO2 ~= 220 GB + compression
        mode3 blocksize=0 density=0x42 compression=1

        # LTO2 ~= 220 GB, no compression
        mode4 blocksize=0 density=0x42 compression=0
}
# end of LTO-3



Note that when we finally got a response from HP, after we had written
this, they sent a stinit.def for a Certance drive, which they had
apparently scrounged off the internet somewhere.  The main difference was
that for mode 4, they used density 0x40, which apparently is LTO-1.

Note also that the stinit.def that I'm using turns auto-lock off.
