The SCSI ID must be unique for each device attached to the SCSI bus. 1 Check for existing SCSI controllers using the following command: % modinfo | grep "SCSI" This will produce output similar to the following: 21 101ea5fa 14d7f 102 1 isp (ISP SCSI HBA Driver 1.205) 25 10207d97 c516 50 1 glm (GLM SCSI HBA Driver 1.154.) This indicates that there are two SCSI controllers on the system, an ISPbased adapter and a GLM-based adapter. For the adapter to which the new tape drive is attached, you will need to determine what SCSI IDs are already used. 2 Determine the SCSI IDs of the existing devices attached to the SCSI controller: For all adapters: % dmesg | egrep ".*xxx.*target" | sort | uniq where xxx = the type of adapter (esp, glm, fas or isp), as appropriate. For example, for an ESP-based adapter: % dmesg | egrep ".*esp.*target" | sort | uniq This produces a list similar to: sd0 at esp0: target 0 lun 0 sd6 at esp0: target 6 lun 0 This indicates that SCSI IDs 0 and 6 are used for existing devices. SCSI ID 7 is generally used for the adapter itself. In this situation, you would use a SCSI ID from 1 to 5 for the new tape drive. configuring the device files Only if necessary, make the following file modifications to enhance performance: 1 In the file /kernel/drv/st.conf, locate these lines Copyright (c) 1992, by Sun Microsystems, Inc. #ident "@(#)st.conf 1.6 93/05/03 SMI" and add the appropriate tape-config-list = lines for your tape drive, as follows: HP Surestore Ultrium drives (there are 6 significant spaces between HP and Ultrium in line 2): tape-config-list = "HP Ultrium", "HP Ultrium", "ULTRIUM", ULTRIUM = 1,0x36,0,0xd639,4,0x00,0x00,0x00,0x40,3; name="st" class="scsi" target=X lun=0; where X is the SCSI target address of the device you have attached. HP Surestore DAT24 drives (there are 6 significant spaces between HP and C1537A in line 2): tape-config-list = "HP C1537A", "HP DDS3 4mm DAT", "HP-data2", HP-data2 = 1,0x34,1024,0xd639,4,0x00,0x13,0x24,0x3,3; name="st" class="scsi" target=X lun=0; where X is the SCSI target address of the device you have attached. HP Surestore DAT24x6 autoloaders (there are 6 significant spaces between HP and C1557A in line 2): tape-config-list = "HP C1557A", "HP DDS3 4mm DATloader", "HP- data2"; HP-data2 = 1,0x34,1024,0xd639,4,0x00,0x13,0x24,0x3,3; name="st" class="scsi" target=X lun=0; where X is the SCSI target address of the device you have attached. HP Surestore DAT40 drives (there are 6 significant spaces between HP and C5683A in line 2): tape-config-list = "HP C5683A", "HP DDS4 4mm DAT", "HP-data2", HP-data2 = 1,0x34,1024,0xd639,4,0x00,0x13,0x24,0x3,3; name="st" class="scsi" target=X lun=0; where X is the SCSI target address of the device you have attached. HP Surestore DAT40x6 autoloaders (there are 6 significant spaces between HP and Ultrium in line 2): tape-config-list = "HP C5713A", "HP DDS4 4mm DATloader", "HP- data2", HP-data2 = 1,0x34,1024,0xd639,4,0x00,0x13,0x24,0x3,3; name="st" class="scsi" target=X lun=0; where X is the SCSI target address of the device you have attached. HP Surestore SDLT drives tape-config-list = "Quantum SuperDLT1", "HP SDLT", "SDLT", SDLT = 1,0x36,0,0xd639,4,0x00,0x00,0x90,0x91,3; name="st" class="scsi" target=X lun=0; where X is the SCSI target address of the device you have attached. HP Surestore DLTvs drives tape-config-list = "BNCHMARKDLT1", "HP DLT1", "DLT1", DLT1 = 1,0x36,0,0xd639,4,0x00,0x00,0x86,0x87,3; name="st" class="scsi" target=X lun=0; where X is the SCSI target address of the device you have attached. 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 /dev/rmt % rm * 3 Do a reconfigure boot: % cd / % touch /reconfigure % 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. See Verifying Installation. hp-data values The values for ULTRIUM and name, which provide normal LTO mode, have the following meanings: Value Meaning 1 0x36 0 or 1024 This value should be 1. Value for an Ultrium drive in /usr/include/sys/mtio.h. Default block size. For variable block size, use 0 instead of 1024 (except with Solaris 2.3, where you should not use 0). 0x639 or A value is derived from constants provided in 0xd639 /usr/include/sys/scsi/targets/stdef.h. The value determines which operations the driver can perform with the attached device by using a unique value for each feature and then adding them together to form 0x639. The features are as follows: 0x001 Device supports variable length records. 0x008 Device can backspace over files (as in the 'mt bsf' option). 0x010 Device supports backspace record (as in 'mt bsr'). 0x020 Device requires a long time-out period for erase functions. 0x0200 Device knows when end of data has been reached. 0x0400 Device driver is unloadable. 0x1000 Time-outs five times longer than normal. 0x4000 Driver buffers write requests and pre-acknowledges success to application. 0x8000 Variable record size not limited to 64 KB. 0x00 Default density setting. Creates a device file with compression disabled. 0x40 The density code for data compression enabled by default. 0x86 Density code 0x87 Density code 0x90 Density code specifying 110 GB (no compression) 0x91 The density code for data compression enabled by default (220 GB). target=X X specifies the SCSI ID (target) of the device. lun=0 Specifies the LUN for the device. © 2001, Hewlett-Packard Company file:///C|/Documents%20and%20Settings/topher.COL-SPRINGS/Desktop/dltvs80%20manual/document/common/unix/reseller/eng/c_sun.htm [11/29/2001 8:34:31 AM]
