Tru64 lto2 configuration

[Frank Beckers]

We use a L700 tape library with 4 IBM lto2 drives and networker as software backup. Recently we changed one of the drives to a HP drive and now we can't get the drive to work correctly from tru64. We checked the path to the device(/dev/ntape/tape_11) tru64 recognizes the device as a hp lto2 scsi. Do we need a new driver for this device? Can anybody help?

Maybe you need something like this:

HP (Compaq) Tru64 UNIX 5.x

1 Add the following entry to /dev/ddr.dbase file:

SCSIDEVICE
Type = tape
Name = â HPâ â Ultriumâ
#
PARAMETERS:
TypeSubClass = lto # Linear Tape Open
BlockSize = 262144
TagQueueDepth = 0
MaxTransferSize = 0xffffff # 16Mb - 1
ReadyTimeSeconds = 120 # Seconds
SyncTransfers = enabled
WideTransfers = enabled
InquiryLength = 0x20
DENSITY:
DensityNumber = 0,1,2,3,4,5,6,7
OneFileMarkOnClose = yes
DensityCode = 0x42
Blocking = 0
CompressionCode = 1
Buffered = 1
Speed = 0
MODESELECT:
ModeSelectNumber = 0
SavePage = No
PageFormat = scsi2
BlockDescriptor = yes
TransferLength = 16
Hdr.Tape.BufferMode = 0x1
Hdr.MediumType = 0
Data.UBYTE[0] = 0x3D # Vendor Unique Page Code 3D
Data.UBYTE[1] = 0x02
20 HP (Compaq) Tru64 UNIX
Data.UBYTE[2] = 0x01
Data.UBYTE[3] = 0x00

2 - Rebuild the kernel by (sbin/ddr_config, then reboot the system with the tape drive attached. The device files for the Ultrium drive will be generated in /dev/tape and /dev/ntape when you reboot.

Thank you very much Danny. The drive works now!
