Solaris didnt configured Tapes. Why.

[Shuegli]

Hi i have a problem.

We have a Server with Solaris 9. This server has a Fibre-Channel connection to a VTL (Virtual Tape Library) this VTl present to the Server a LTO

with inquire it looks like this.
crmdb1 # inquire
scsidev@3.0.0:IBM ULTRIUM-TD1 18N2|Tape, /dev/rmt/0cbn
S/N: 8AU640021Z
WWNN=4850202020202020

and it worked fine.

then we changed to LTO3 and i present 4 LTO3 Drives to the Server.
In the /kernel/drv/st.conf i insert the following Lines.
name="st" class="scsi" target=0 lun=0;
name="st" class="scsi" target=0 lun=1;
name="st" class="scsi" target=0 lun=2;
name="st" class="scsi" target=0 lun=3;

The first line already exist i insert the 3 other lines.
Inquire sees now that:
scsidev@3.0.0:IBM ULTRIUM-TD1 18N2|Tape, /dev/rmt/0cbn
S/N: 8AU640021Z
WWNN=4850202020202020
scsidev@3.0.1:HP Ultrium 3-SCSI G27D|Tape

S/N: 8AU6400220
WWNN=4850202020202020
scsidev@3.0.2:HP Ultrium 3-SCSI G27D|Tape

S/N: 8AU640023F
WWNN=4850202020202020
scsidev@3.0.3:HP Ultrium 3-SCSI G27D|Tape

S/N: 8AU640023G
WWNN=4850202020202020
the first(the old one) is still seen as a LTO1 the other 3 are seen the correct way.
BUT the 3 new Drives are not seen by the OS (they downt have a /dev/rmt/xcbn)
then i checkt the file /kernel/drv/sd.conf the first 2 lines were already in so i insert the following lines.
name="sd" class="scsi" class_prop="atapi"
target=0 lun=0;
name="sd" class="scsi" class_prop="atapi"
target=0 lun=1;
name="sd" class="scsi" class_prop="atapi"
target=0 lun=2;
name="sd" class="scsi" class_prop="atapi"
target=0 lun=3;

in the lpfc.conf file i have the following:
log-verbose=0x0;
log-only=1;
fcp-bind-method=3;
automap=1;
lun-queue-depth=30;
tgt-queue-depth=0;
no-device-delay=1;
network-on=0;
xmt-que-size=256;
scan-down=1;
linkdown-tmo=30;
nodev-holdio=0;
nodev-tmo=30;
delay-rsp-err=0;
num-iocbs=256;
topology=0;
num-bufs=128;
ip-class=3;
fcp-class=3;
use-adisc=0;
extra-io-tmo=0;
dqfull-throttle-up-time=1;
post-ip-buf=128;
dqfull-throttle-up-inc=1;
ack0=0;
cr-delay=0;
cr-count=1;
discovery-threads=1;
link-speed=0;
fdmi-on=0;

then i used the devfsadm command but it is still not working.

Has anyone a idee?

thanks for your help

Shouldn't you be modifying st.conf (for SCSI tapes), not sd.conf (for SCSI disks)?

Annihilannic.

 

[Shuegli]

i modifyed st.conf
i inserted the following lines
name="st" class="scsi" target=0 lun=1;
name="st" class="scsi" target=0 lun=2;
name="st" class="scsi" target=0 lun=3;

then with the "inquire" command i see the drives
scsidev@3.0.0:IBM ULTRIUM-TD1 18N2|Tape, /dev/rmt/0cbn
S/N: 8AU640021Z
WWNN=4850202020202020
scsidev@3.0.1:HP Ultrium 3-SCSI G27D|Tape

S/N: 8AU6400220
WWNN=4850202020202020
scsidev@3.0.2:HP Ultrium 3-SCSI G27D|Tape

S/N: 8AU640023F
WWNN=4850202020202020
scsidev@3.0.3:HP Ultrium 3-SCSI G27D|Tape

S/N: 8AU640023G
WWNN=4850202020202020

but solaris still didnt config the drives if i make the command devfsadm.

Try a reconfigure reboot maybe? Unfortunately I don't have a Solaris system with tape drives attached any more to experiment with, so I can't help much more.

What backup software are you using? Is this Symantec/Veritas Netbackup and if so what version? I know Solaris 9 is supposed to be able to do this without a reboot, but I think you're looking at a reboot reconfigure to see those devices properly. Let me know what kind of backup environment you're running because there are couple different approaches you want to take depending on what you have to save yourself headaches later.

@graveslu
I use EMC Networker 7.4.3
But the Backup Software isnt the problem.
Its a Solaris problem.
i present 4 LTO3 Drives to the Server
with the command "inquire" (a Networker command) i can see what device are presented to the server over Fibre-channel (for example if i present SAN Storage Disks over Fibre-Channel then i will also see them with the inquire command. i see the 4 LTO3 Drives.(see mail Nr 3 from me)
BUT Solaris makes only connection to the first drive the other 3 didnt have a /dev/rmt/Xcbn that is the problem.

Hi Shuegli.

Try cfgadm -o show_FCP_dev to view the all device attached to the system via fiber channel. Verify that all controllers are online an configured. If some of they are not configured try cfgadm -c configure "controler". For example cfgadm -c configure c11


then devfsadm.

So....how did it work out for you?

 

[Shuegli]

Hi
I reboot the Server today with the reconfigure option.

Now i have all 4 LTO3 Drives and they work normal.

So thanks to all for the help
