This could be handy info for some. The target is set up on linux with stgt, the initiator is on opensolaris. Although most of it is probably well know to Solaris fans, it took me a bit of time to figure out to get the vtl (virtual tape library) target working fine under opensolaris. For those who want to give it a try, here are the commands: For normal disk and cd targets no files have to be changed. All you need is the following: # svcadm enable iscsi_initiator and check if it is online: # svcs iscsi_initiator the state should be online. Now we add the discovery address to the initiator: # iscsiadm add discovery-address <IP of target> Now we configure the discovery mode to sendtargets: # iscsiadm modify discovery -t enable Check the target: # iscsiadm list target -S And create the device files: # devfsadm -i iscsi Tape devices will be shown properly, but not the changer device, this takes a bit more work. Two files need to be changed, and a reboot is needed to set things up properly. In the file /etc/driver_aliases the two lines sgen "scsa,08.bfcp" sgen "scsa,08.bvhci" need to be replaced with sgen "scsiclass,08" The file /kernel/drv/sgen.conf, which is basically all commented out needs to have the following lines: device-type-config-list="changer","sequential"; inquiry-config-list= "*", "*"; name="sgen" class="scsi" target=0 lun=4; name="sgen" class="scsi" target=1 lun=4; name="sgen" class="scsi" target=2 lun=4; name="sgen" class="scsi" target=3 lun=4; name="sgen" class="scsi" target=4 lun=4; name="sgen" class="scsi" target=5 lun=4; name="sgen" class="scsi" target=6 lun=4; name="sgen" class="scsi" target=7 lun=4; name="sgen" class="scsi" target=8 lun=4; name="sgen" class="scsi" target=9 lun=4; name="sgen" class="scsi" target=10 lun=4; name="sgen" class="scsi" target=11 lun=4; name="sgen" class="scsi" target=12 lun=4; name="sgen" class="scsi" target=13 lun=4; name="sgen" class="scsi" target=14 lun=4; name="sgen" class="scsi" target=15 lun=4; For the last bit it should be noted that my changer was set to lun 4, and since I don't know which target I put all target numbers in (0-15). After these modifications the best is to reboot the machine, and do the iscsi commands above, and he presto it works: In my case, three tape drives and one changer: root at solar:/kernel/drv# iscsiadm list target -S Target: iqn.2008-09.com.example:server.tape Alias: - TPGT: 1 ISID: 4000002a0000 Connections: 1 LUN: 4 Vendor: STK Product: L700 OS Device Name: /dev/scsi/changer/c0t0d0 LUN: 3 Vendor: HP Product: LTO3 ULTRIUM OS Device Name: /dev/rmt/2n LUN: 2 Vendor: HP Product: LTO3 ULTRIUM OS Device Name: /dev/rmt/1n LUN: 1 Vendor: HP Product: LTO3 ULTRIUM OS Device Name: /dev/rmt/0n root at solar:/kernel/drv# mtx -f /dev/scsi/changer/c0t0d0 status Storage Changer /dev/scsi/changer/c0t0d0:3 Drives, 29 Slots ( 5 Import/Export ) Data Transfer Element 0:Empty Data Transfer Element 1:Empty Data Transfer Element 2:Empty Storage Element 1:Full :VolumeTag=A0000001 Storage Element 2:Full :VolumeTag=A0000002 Storage Element 3:Full :VolumeTag=A0000003 Storage Element 4:Full :VolumeTag=A0000004 Storage Element 5:Full :VolumeTag=A0000005 Storage Element 6:Full :VolumeTag=A0000006 Storage Element 7:Full :VolumeTag=A0000007 Storage Element 8:Full :VolumeTag=A0000008 Storage Element 9:Empty:VolumeTag= Storage Element 10:Empty:VolumeTag= Storage Element 11:Empty:VolumeTag= Storage Element 12:Empty:VolumeTag= Storage Element 13:Empty:VolumeTag= Storage Element 14:Empty:VolumeTag= Storage Element 15:Empty:VolumeTag= Storage Element 16:Empty:VolumeTag= Storage Element 17:Empty:VolumeTag= Storage Element 18:Empty:VolumeTag= Storage Element 19:Empty:VolumeTag= Storage Element 20:Empty:VolumeTag= Storage Element 21:Empty:VolumeTag= Storage Element 22:Empty:VolumeTag= Storage Element 23:Empty:VolumeTag= Storage Element 24:Full :VolumeTag=CLN00001 Storage Element 25 IMPORT/EXPORT:Empty:VolumeTag= Storage Element 26 IMPORT/EXPORT:Empty:VolumeTag= Storage Element 27 IMPORT/EXPORT:Empty:VolumeTag= Storage Element 28 IMPORT/EXPORT:Empty:VolumeTag= Storage Element 29 IMPORT/EXPORT:Empty:VolumeTag= -- To unsubscribe from this list: send the line "unsubscribe stgt" in the body of a message to majordomo at vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html |
