Need help for configuring MSL 6000 on Solaris 10 and SLES 9

[Kishan Kumar]

HI,

I have a MSL 6000 Tape library connect to a FC switch through an NSR router(SCSI to FC router).I have connected 3 hosts in SAN to the FC switch.On HP-UX machine which is successfully configured For MSL 6000 and DP 5.5 installed which "devbra -dev" shows the changer as well as two tape drives.

However on the other two hosts solaris 10 and Sles 9 i have problems with the OS configuration itself for MSL 6000.

On solaris 10 when i try to load the sst drive (I followed DP documentation .SST driver comes along with DP software)it says driver loaded but failed to attach.( ie add_drv sst).This is a Sparc machine.
when i run "devbra - dev" it shows the 2 drives but not the changer.

ON SlES 9 i dodnot knwo how to configure MSL 6000 at the OS level itself forget about through DP.

Can anyone please help.Both the SLES 9 and Solarsi10 has qla2300 with appropraite drivers installed

Thanks in advance
Kishan

Hi,

Did you managed to get the problem resolve. I have the exact problem as yours. I am using MSL 5030

[Kishan Kumar]

YUp,

You need to populate your sst.conf file provided with DP

[kholikt]

Hi,

Can I take a look of how your sst.conf look like? What is the steps you get it resolve?

# Each entry should have 2 fields; but may have 3. Fields are separated

# The fields are:
#
# devfs-spec: a keyword-value set of devfs specifications, describing the set

#
# The keywords are:
#
# type - The devinfo node type (see for possible values)
#
# name - the devinfo node name (the part of a /devices entry that appears
# before the '@' or ':').
#
# addr - the devinfo node address part (the portion of the name between
# the '@' and the ':').
#
# minor - the minor-attributes (the portion of a /devices name after the
# ':').
#
# The keywords are separated from their valuse by an equals ('=') sign;
# keyword-value pairs are separated from each other by semicolons (';').
#
# dev name - the /dev name corresponding to the devfs node described by

# /dev; THE INITIAL /dev/ SHOULD NOT BE SPECIFIED!
# The name can contain a number of escape-sequences to include parts of

#
# \D - the devfs 'name' field
#
# \An - the 'n'th component of the address field (n=0 means the whole
# address field)
#
# \Mn - the 'n'th component of the minor field (n=0 means the entire
# minor field).
#
# \Nn - a sequential counter, starting at n (a *single* digit, giving
# a starting range of 0 through 9).
#
# extra dev link - a few devices need a second link; that is, a second link

Hi,

Thanks for the information but may I know "w100000e00202dc0f,1", Is this a world wide name use in the SAN switch.

[Kishan Kumar]

yes

[kholikt]

Hi,

Sorry I am not very familiar with SAN. This is a port WWN. I can see many WWN there, even each port has their unique WWN. I suppose I should put in the port WWN that this library is connected

[Kishan Kumar]

yes the port wwn will do

w100000e00202dc0f,1

The number "1" in your /etc/devlink.tab at the back is this a Lun number. How can I find out my Lun number?

[kholikt]

still no luck

devfsadm: driver failed to attach: sst
Warning: Driver (sst) successfully added to system but failed to attach

I have same problem,but hosts is IBM p550,AIX 5.3. On AIX 5.3 only tape drive device name,no changer.

wait for answer.....???

I can tell you it is hopeless. I am looking for this solution till now I give up already. I am putting a Wintel machine in the SAN to control the robotics arms. If you can switch to Netbackup please do so it has a better support than DP.

[Kishan Kumar]

HI ,

Regading MSL Robotic support on AIX 5.3 i would like to tell you that AIX 5.3 doesnot support Robotic control for MSL and its there in one of the IBM sites when i googled for it.so you have to do away with the drives only and not the robotic on AIX and as you knwo it AIX problem and no where related to MSL.

Regarding Netbackup i dont have much comment on it.The problem we discuss here is with configuration of Devices on operating systems and not the backup tool itself. As i ma using Dp from quite a long time i understand the advantage of DP an dam not aware much of NBU stuff.

Regading teh configuration of MSL on solaris , i suggest you please contact the SUN support guys for the same as i dint face much of a problem when confguring MSL on solaris using DP provided drivers.I suggest you redo the whole thing once again.

regards
kishan

The problem is something to do with the ssh remote execution

ssh user@hostname sar -u 1 5 > /tmp/sarcheck

The above line will only work if you run the script manually. It won't work if it was scheduled as cron.

Hi Kishan,

Have you got the problem solved finally. If so, how? I am also running in to same problem and strugging for last two months.

Thanks

Now it looks much better. add_drv sst is not reporting any problem. But if I execute uma -ioctl to changer device it is not sensing.

Any idea what is wrong?

NOTE On Solaris systems, (especially in case of Solaris 64-bit), links to the
SCSI control device (picker) are not always created automatically. In this
case, create symbolic links. For example:
ln -s /devices/pci@1f,4000/scsi@3,1/sst@4,1:character
/dev/rsst4
You can use the Data Protector uma utility to verify the device. To
check the picker of the SCSI Exchanger device from the previous
example (using the SCSI port 4), enter:
echo â inqâ |/opt/omni/lbin/uma -ioctl /dev/rsst4
The picker must identify itself as a SCSI-2 device library. The library
can be checked by forcing it to initialize itself. The command is:
echo â initâ |/opt/omni/lbin/uma -ioctl /dev/rsst4
Make sure you use Berkeley-style device files, in this case,
/dev/rmt/ohb (not /dev/rmt/0h)for the exchanger drive and
/dev/rsst4 for the SCSI control device (picker).

The baove example is for a scsi device.
in case of a Fc device

/devices/pci@1f,4000/scsi@3,1/sst
{wwn number}:character
/dev/rsst{wwn number}

Finally I could solve the problem. Configuration of NS-E1200 router was not correct and I had to correct the mapping.

Thanks Kishan for giving me an idea about sst entry for FC device (which is not available in DP manual)

BTW, are you using default st.conf for LTO3? It has got entries for LTO1 and LTO2. However, I have got it from HP site and added to st.conf. Need more testing.

Hi Kishan,

Need your help. Here is my "cfgadm -al -o show_FCP_dev" output.

c4 fc-fabric connected configured unknown
c4::100000e00222a8f1,0 med-changer connected configured unknown
c4::100000e00222a8f1,1 tape connected configured unknown

I have attached my st.conf and sst.conf look like. I haven't apply the changes yet as wake for approval of downtime.

Currently I have a very strange problem, the MSL 5030 tape drive cannot archive it performance and the compression doesn't work at all. For example the backup data is 280G but the MSL tape drive after backup 100GB it will ask for more tape. But for the same server I have another standalone ultrium 2 scsi attached, using the same LTO1 catrdge it can backup 280GB of data.

mt -f /dev/rmt/1mbn config
"HP Ultrium 1", "HP Ultrium LTO", "CFGHPULTRIUMLTO";
CFGHPULTRIUMLTO = 2,0x3B,0,0x18659,4,0x40,0x40,0x40,0x40,3,60,300,600,1200,600,600,18000;

mt -f /dev/rmt/2mbn config
"HP Ultrium 2", "HP Ultrium LTO 2", "CFGHPULTRIUMLTO2";
CFGHPULTRIUMLTO2 = 2,0x3B,0,0x18619,4,0x40,0x40,0x42,0x42,3,60,300,600,1200,600,600,18000;

[kholikt]

I am getting a little bit closer now at least I can see the sst but I still cannot control the arm as I still getting the error message

Cannot open exchanger control device (Device type mismatch)

I have attached my st.conf sst.conf and my devlink.tab

Dear Kishan

I'm also having IBM AIX v5.3 and MSL6030 FC Library with HP Ultrium 2 LTO SCSI Drives. AIX does detects this drives as Other FC SCSI Tape Drive (OST) - rmt1 and rmt2 with connection seetings as 2 nd 3 (where as Drive SCSI IDs are 1 and 2).

rmt0 is an directly attached scsi drive and is working fine.

When cfgmgr is executed it does report devices.fcp.array and devices.fcp.changer not available.

My problem is tar,dd or cpio none works with the tape. Could you pls. throw some more light on how did you manage to make the drives working in AIX.

Regards
Ali
