无法识别SUN L25带库?solaris9(E3000+emulex9002卡）＋NBU5.1
Description: Top
FC420 is a L25/100 add-on PCI card peripheral from ATTO that installs
inside the L25/100 tape libraries. The FC420 SCSI to Fibre-
Channel bridge is used to allow SCSI tape devices in the L25/100
libraries to join a SAN.
Below procedures detail how to configure Netbackup and Enterprise Backup
Software environments to detect tape drives behind a FC420 bridge.
In this example, the L25/100 is configured with two tape drives.
From the L25/100's front panel, target IDs are set as follows:
Robot = ID-0
Drive-1 = ID-1
Drive-2 = ID-2Document Body: Top
Ensure the L25/100 is connected, powered and has passed its internal
diagnostics from the panel.
Check that serialization is enabled from the front panel of the L25/L100
Library. If it is disabled, then enable it by:
1) On the main screen, press Menu. The GUI displays the Menu screen.
2) Press Config. The GUI displays the Configuration screen.
3) Press the Up or Down buttons until Serialization is highlighted.
4) Press Select.
5) Use the Up or Down buttons to select Enabled.
6) Press Select.
7) Press Main to return to the main screen.
Prior to following steps you must insure that you can can see tape drives and
changer in Solaris first.

VERITAS NetBackup
-----------------
If you are using VERITAS NetBackup 4.5 and later, you will need to follow
the procedure outlined below. In a bridge environment, sg.build will not
detect all the devices attached through a FC420 bridge. Some manual
configuration of sg driver will be needed.
1. Run sg.build to detect devices as needed.
- This will create st.conf, sg.conf and sg.links files as needed.
- The st.conf file can be appended to /kernel/drv/st.conf.
- The sg.conf and sg.links files will need to be edited.
2. Run "cfgadm -la -o show_FCP_dev" to determine which devices are seen
through the OS and their luns.
Sample output:
Ap_Id Type Receptacle Occupant Condition
c7 fc-fabric connected configured unknown
c7::2100001086107794,0 med-changer connected configured unknown
c7::2100001086107794,1 tape connected configured unknown
c7::2100001086107794,2 tape connected configured unknown
c7::2100001086107794,3 ESI connected configured unknown
Note that in our example:
* 2100001086107794 is the needed wwn.
* The media-changer/robotics arm is located at lun 0.
* The two drives are located at luns 1 and 2.
3. Edit the sg.conf file just created.
Sample output:
name="sg" parent="fp" target=0 lun=0 fc-port-wwn="2100001086107794";
name="sg" parent="fp" target=0 lun=1 fc-port-wwn="2100001086107794";
Note that the entry for lun 0, and possibly lun 1, device already
exists.
There needs to be added entries for the other luns as well. All media-
changer and tape devices will need their own entry. In our example, the
final entries related to this device will be:
name="sg" parent="fp" target=0 lun=0 fc-port-wwn="2100001086107794";
name="sg" parent="fp" target=0 lun=1 fc-port-wwn="2100001086107794";
name="sg" parent="fp" target=0 lun=2 fc-port-wwn="2100001086107794";
Refer to the VERITAS NetBackup Admin Guide for more details on sg.conf
entries.
4. Edit the sg.links file just created.
Sample output:
type=ddi_pseudo;name=sg;addr=w2100001086107794,0; sg/c\N0t\A1l0
type=ddi_pseudo;name=sg;addr=w2100001086107794,1; sg/c\N0t\A1l1
Note that the entry for lun 0, and possibly lun 1, device already
exists.
There needs to be added entries for the other luns as well. All media-
changer and tape devices will need their own entry. In our example, the
final entries related to this device will be:
type=ddi_pseudo;name=sg;addr=w2100001086107794,0; sg/c\N0t\A1l0
type=ddi_pseudo;name=sg;addr=w2100001086107794,1; sg/c\N0t\A1l1
type=ddi_pseudo;name=sg;addr=w2100001086107794,2; sg/c\N0t\A1l2
Note that the lun is specified in the addr as well as the sg path.
Refer to the VERITAS NetBackup Admin Guide for more details on sg.links
entries.
5. Continue the configuration by using the sg.install link as specified
in the VERITAS NetBackup Admin Guide.
6. Verify that sg driver is attached to the devices by running sgscan.
The media changer and the drives should appear now.
Sample output:
/dev/sg/c0tw2100001086107794l0: Changer: "M4 DATA MagFile"
/dev/sg/c0tw2100001086107794l1: Tape (/dev/rmt/3): "QUANTUM SDLT320"
/dev/sg/c0tw2100001086107794l2: Tape (/dev/rmt/2): "QUANTUM SDLT320"
NOTE: These steps will need to be repeated if sg.build is run again and
the devices are no longer seen. |
