/dev/rmt


Step 1.
create zone for backup server HBA and LTO tape library on the switches

Backup_LTO_PCIe4_2
backup_server-> HBA Port WWN: 10000000c9724c87 - (OS Dev name: /dev/cfg/c5)
LTO4_TAPE_DRV_1 -> HBA Port WWN: 500308c09d274005

Step 2.
Active the new zone on the switch, make sure the new zone is listed in the zones config.

Step3.
make sure you see connectivity from the sun box to the tape library
#fcinfo hba-port -l
HBA Port WWN: 10000000c9724c87
OS Device Name: /dev/cfg/c5 <------- device name
Manufacturer: Emulex
Model: LPe11002-S
Firmware Version: 2.72a2
FCode/BIOS Version: 1.50a9
Type: N-port
State: online <------ check this status
Supported Speeds: 1Gb 2Gb 4Gb
Current Speed: 4Gb
Node WWN: 20000000c9724c87
Link Error Statistics:
Link Failure Count: 0
Loss of Sync Count: 4
Loss of Signal Count: 1
Primitive Seq Protocol Error Count: 0
Invalid Tx Word Count: 12
Invalid CRC Count: 0

#fcinfo hba-port -l | grep online
State: online
State: online
State: online
State: online

quick way to check is grep for online, all the connected HBA should be online.
here in above example, 2 HBA are connected to DS4800 and 2 are connected to TS3310

online status tells you the hbas are connnected to the switch. however before using attaching WWN from the server to WWN LTO make sure you have zone enabled.


Step 4.
Once you have the connectivity,
take a look at c5
#cfgadm -al
connect C5 with the LTO WWN

#cfgadm -c configure c5::500308c09d274005 <------- this is LTO WWN
#cfgadm -c configure c6::500308c09d274001 <------- this is LTO WWN

result looks like this
c5 fc-fabric connected configured unknown
c5::500308c09d274005 tape connected configured unknown


Step 5.
then you should see the /dev/rmt devices
#ls -l /dev/rmt/0 <--------- first tape drive
0 0bn 0cb 0cn 0hb 0hn 0lb 0ln 0mb 0mn 0u 0ubn
0b 0c 0cbn 0h 0hbn 0l 0lbn 0m 0mbn 0n 0ub 0un

#ls -l /dev/rmt/1 <--------- second tape drive

in the above example you have two tape connected.



Step 6.
Check the device paths for FC tape drives
# luxadm inq /dev/rmt/0h

INQUIRY:
Physical Path:
/devices/pci@0/pci@0/pci@8/pci@0/pci@2/SUNW,emlxs@0,1/fp@0,0/st@w500308c09d274005,0:h
Vendor: IBM
Product: ULT3580-TD4
Revision: 7A31
Serial Number 1310048383

Removable media: yes
Medium Changer Element: no
ISO version: 0
ECMA version: 0
ANSI version: 3 (Device complies to SCSI-3)
Terminate task: no
Response data format: 2
Additional length: 0x35
Command queueing: no

00 00 00 00 ....



if you here without any problems, you can do a quick tar test writing to tape directly.
Go ahead and manually put a media in tape drive and try these commands

1. tape drive status:
# mt -f /dev/rmt/0 status
# mt -f /dev/rmt/1 status


2. Backup directory /www and /home with tar command (z - compressed):
# tar -cvf /dev/rmt/0 /home



Step 7.
Next step is making the robot working, which moves the tapes to tape drive 1 and 2

Download these drivers for solaris
ftp://ftp.software.ibm.com/storage/devdrvr/Solaris/

Download IBM TotalStorage Tape Diagnostic Tool (ITDT) v2.0

the file name is itdtinst2.2Solaris
>>1. Download itdtinstSolaris to a directory of your choice.
>>2. Make itdtinst executable with "chmod 700 itdtinstSolaris".
>>3. Execute itdtinstSolaris.
>>4. Configure the sgen driver


itdt scan output

#configure the sgen drivers for
make sure the output of /sgen_solaris_conf.sh matches the /kerner/drv/sgen.conf

the /kernel/drv/sgen.conf file is missing something in order to mtx works properly.
On the sgen.conf example below, target 5 is a tape changer and target 6 is the tape drive:
device-type-config-list="changer","sequential
name="sgen" class="scsi" target=5 lun=0;
name="sgen" class="scsi" target=6 lun=0;

# mtx -f /dev/scsi/changer/c5t500308C09D274005d1 inquiry
- testing the robot status

#/opt/csw/sbin/mtx -f /dev/scsi/changer/c5t500308C09D274005d1 load 1 0
- this commands tells the robot to pick the tape from slot 1 and put it in drive 0


Step 8.
On Solaris, use either the IBMtape driver or the native st driver
..... On HP-UX, use the IBM atdd tape device driver



#ls -l /dev/rmt/*l
lrwxrwxrwx 1 root root 90 Sep 22 14:54 /dev/rmt/0l -> ../../devices/p ci@0/pci@0/pci@8/pci@0/pci@2/SUNW,emlxs@0,1/fp@0,0/st@w500308c09d274005,0:l

In the preceding line example /dev/rmt/0l is controller by st device driver and associated with the device at fiber channel using EMULEX cards at LUN 0

If it shows something like
lrwxrwxrwx 1 root root 90 Sep 22 14:54 /dev/rmt/0l -> ../../devices/iommu@f,e000000/sbus@f,e0001000/QLGC,isp@3,10000/st@2,0:1

then it is st device driver and associated with SCSI address 2, LUN 0

-------------------------------------------------------------------------------------------
Here we need to note the special file number, owning driver, SCSI target address and LUN
