Networker can not see new CDL 4100

I have a NetWorker server that is currently attached to IBM 3584 tape library. I needed to attach it to CDL 4100 which is also emulating IBM 3584, when everything was completed and i actually saw new tape drives and changer in device manager i could not get NetWorker to recognize the library. When i run inquire i get this:

C:\Documents and Settings\SystemCommander>inquire
scsidev@0.0.0:HL-DT-STRW/DVD GCC-4244N1.02|CD-ROM
scsidev@1.0.0:IBM     ServeRAID       6.10|Disk, \\.\PHYSICALDRIVE0
                                           S/N: 8000C9E700

scsidev@5.1.1:IBM     03584L22        5550|Autochanger (Jukebox), \\.\Changer0
scsidev@5.2.0:IBM     03584L32        4.02|Autochanger (Jukebox), \\.\Changer1
scsidev@5.2.1:IBM     03592J1A        044C|Tape
scsidev@5.2.2:IBM     03592J1A        044C|Tape
scsidev@5.2.3:IBM     03592J1A        044C|Tape
scsidev@5.2.4:IBM     03592J1A        044C|Tape
scsidev@5.2.5:IBM     03592J1A        044C|Tape


\\.\Tape6 and \\.\Tape5 are the physical library, while the other 044C drives are from CDL. I am guessing this is the problem and they should show up just like the physical drives. Any ideas what i could try next ?

If you see devices you can skip NW backup part and proceed with NW.

RSM is disabled, we are emulating the same drive type as on the physical library (IBM 3592 drives). In device manager everything looks good, we install the same ibm drivers that we used for physical drives. We bounce the box a few times too ..no luck.

I assume CDL library is on 5.2.0... if you do sjirdtag 5.2.0 do you get expected output?

Also, what version of NW is that? inquire output looks like pre-7.3.x version. I shortly had tested 7.2.2 with CDL under HPUX and it worked, but with 7.3.x drivers were recognized by inquire as Virtual Drives and officially support was virtual drives was added somewhere in 7.3.x so we went on with that version.

From inquire output those drives do not have drive address associated - that usually indicates tape drives does not exist or it is not hooked to new drive. I assume you emulate same drives as on physical library so that should not be your case. Try inquire -cl command to avoid inquire using system cache. Also, check device manager to see if it complains about new tape drives as driverless. Most importantly, make sure RSM is disabled.

Btw, are you really running everything over 1 HBA?

Also, in device manager you should see device paths. What do you get when you test them with mt -f status? All normal?

hrvoje

before we get into details let me tell you what we are trying to do. Let me know if its doable, forget my original post :).

We have purchased a storage node license ( i think that what its called), right now we have a networker server 7.x .. we want to setup another system that will be configured as storage client, i will present CDL lirary to this node and then register this node within Networker. My altimate goal is to run backup on the storage node while all the metadata/schedules etc is stored on the Networker server. Do you have exprience with this kind of setup ? As you probably guessed i am not a networker admin but i am responsible for backup infrastructure.

sorry ..i could not run these commands ..when i presented these new drives, it re-numbered physical drives, so i had to pull CDL drives away to keep backups running tonight. We decided to go with storage node option, so i will present CDL library to a brand new box and i guess register it with NetWorker. Any good documentation you can point to on how to set it up ?

Thanks

Check jbconfig manual. If you present CDL on box (including "robotics") go to cmd and run jbconfig -s and just follow instructions (go for autodetected library option). Before you do this you may wish to make sure you know what is physical and corresponding logical (OS) device order. Usually NW knows this itself and will do it by itself for you during jbconfig.

Are you talking about built in SN inside CDL? That one is based on early 7.3 code so I would stay away from that.

You can also buy a built in storage node license for the DL4100.

If it is library license based on disk capacity then you already have VTL license. I never used VTL license before so I have no idea how it works with 7.3.x.

Yes, this is pretty much basic NW setup so no worries there. You will also need autochanger license (well, that's were things get complicated as EMC has now something called VTL license which in enforced as of NW 7.4 released yesterday, but before you moved to that EMC will need to exchange your existing autochanger license for VTL one).

i don't think we are going to 7.4 very soon, i was told we bought a storage node license and a library license for 25 Terabytes. Would that be sufficient ?

yes..we had one license for physical library which was based on tape slots ...this one was sold based on 25T of CDL capacity. So where do i start ? Any docs you guys could recommend ?

In reality jbconfig manual is enough if just adding library. For more, administration guide available from Powerlink is the way to go.
