Cannot get Dell PV122T LTO2 to work on AIX5.2

[dragony]

Hello,

We are trying to get our new Dell PV122T LTO2 Autoloader to work with TSM 5.2.3 on IBM p650 running AIX5.2. But we can't even get the OS to see the library, and the tape drive it sees can't be added to TSM either.

Dell doesn't officially support AIX, i.e. no AIX driver, but they do point us to the IBM's Tivoli Supported Devices webpage, which does list Dell PV122T as supported on AIX since TSM 5.1.5.

Both our local Tivoli and IBM support are stuck where we are...at the OS level. AIX can't see the library, and we can't add the tape drive in SMIT.

Thanks in advance for any help or suggestion.

Did you install AIX first, and then connect the library?
If so, Connect the library first, and then install AIX so AIX can get the correct drivers for the Library/TapeDrives.

Try running, cfgmgr -v

lsdev -Cc tape what does that give you?

Hi Mag0007,

Thanks for the advice. But this is a running Production server, so I can't just re-install AIX.

Here is what lsdev -Cc tape gave us:
rmt0 Available 1D-08-00-0,0 SCSI 4mm Tape Drive
rmt1 Available 1V-08-00-3,0 IBM 3580 Ultrium Tape Drive
rmt2 Available 1D-08-00-6,0 IBM 3580 Ultrium Tape Drive
rmt3 Available 1D-09-00-2,0 LTO Ultrium Tape Drive
smc0 Available 1V-08-00-1,0 IBM 3581 Tape Medium Changer

rmt0 is the built-in 4mm Tape drive
rmt1 is the LTO1 tape drive inside the IBM3581 autoloader (smc0)
rmt2 is the single drive LTO1 connected to the same SCSI card but different channel from the Dell PV122T
rmt3 is the IBM LTO2 tape drive inside the Dell PV122T

As you can see, we should have smc1 for the autoloader device of Dell PV122T, but we don't.
Also, I don't think the description "LTO Ultrium Tape Drive" is quite right either, but that may not be important, I guess.

Any advice?

Thanks a bunch,
Chutikorn

Since the library is support, from the IBM site that you mention. TSM Server 5.1.5.0 is the minimun TSM Server version that will work with the library

Since the library is from Dell, we would using the TSM Device Driver.

I do not know if the drives that we are using are from IBM or from another company.

If the tape drives are from IBM, then we would be using the ultrium device driver.

If the tape drives are not from IBM, then we would be using the TSM Device Driver.

The only time that we use the native device driver is if the library/tape drive is from IBM.

Good Luck,

Hi LED888,

Well it is 2 separated devices as you said.
1> Dell PV122T library, non-IBM --> TSM driver
2> IBM LTO-2 Tape drive, IBM --> IBM ATape driver

I guess we came the right way by downloading IBM ATape driver for the tape.

But when you said that we would use TSM driver for non-IBM device, does that mean it is OK to not see the non-IBM device at the OS (AIX) level? Our local support is saying that if we cannot control the library (non-IBM device) with the OS, then TSM will not be able to control it either.
We've tried to add the library using SMIT or SMITTY, but we keep getting "Not enough memory to complete that operation" error.

Any guess?

Thanks a bunch,
Chutikorn

Chutikorn,

For the following, it is correct.
1> Dell PV122T library, non-IBM --> TSM driver
2> IBM LTO-2 Tape drive, IBM --> IBM ATape driver

Even though we are using the TSM Device Driver for the changer, via the operating system there should be an smc1.
The operating system have to see the device. The TSM Server does not control the device directly, the TSM Server access the device via the operating system. If the operating system can not see the device, the TSM Server is not going to be able to access the device either.

Strange that we recieve the following message via SMIT,
"Not enough memory to complete that operation."

I do not suspect that it takes a lot of memory to set the device via SMIT.

Rather adding the device manually via SMIT or SMITTY.

Since the TSM Device Driver is installed, run cfgmgr .
Then run lsdev -Cc tape and see if the device is present if not then check the error report.

Good Luck,
Sias

Hi LED888,

Tried your suggestion. Running cfgmgr didn't add scm1 as we hoped. lsdev -cC tape still give the same 5 devices (4 rmt's and 1 smc0).

I've captured the output of cfgmgr, but can't seem to find any obvious error. The PV122T is connected to scsi4, so that's what I looked for. Can you suggest any special things too look for in the cfgmgr output?

Thank you very much,
Chutikorn

Chutikorn,

Interesting, I to would have expected the cfgmgr to find the device.

Were there any error message in the AIX errpt?
I do not expect any, but check on the half chance.

Stupid question, the TSM Device Driver is installed?

I know that we try to use SMIT to define the device and we recieve the following message "Not enough memory to complete that operation." How much memory do we have?
Are we able to shut down some application to free up some memory?
