HP LTT tools on Mac and LTO 6

Hi Folks

 

We have just recieved a new Scalar i40 from Quantum. It is reporting some strange re-write errors to our backup software (www.archiware.com).

 

I have updated the firmware on the drives... and the error count has reduced. For clarity, the software reads:

 

"error counters are read with a "LOG SENSE" SCSI command 0x4D from the drive's SCSI pages 0x02 and 0x03." as the re-write error.

 

However, reading the device logs using LTT, doesn't show anything suspect.

 

I have been trying to run the 'drive assesement test on the drives using LTT tools on the mac server that is running all of this... and i get an error saying that the drive is 'write protected'. When i scan the device i get this:

 

Product ID : Ultrium 6-SCSI
Drive Technology : LTO
Mech. Serial Number : C38D6F7000
Firmware Rev : 236Z/OEM
Target ID : 171
Target LUN : 219
OBDR Capability : Not Supported
WORM Capability : Supported

Cartridge Information (for cartridge currently in drive):
Cartridge Type : LTO 6 Data
* Capacity : 5000 GB (2:1 data compression)
Write Protected : No
Barcode : Not Set
Cartridge Partitioned: No

 

 

but when i then run the test i get:

 

- Test 'LTO Drive Assessment test' started on device 'HP Ultrium 6-SCSI' at address 'HBA_6151_6429'
- Operations Log
- LTO Drive Assessment Test Options

- The cartridge currently loaded in the drive is write protected.
- This test cannot be performed on a write protected cartridge.

So i am presuming this may be to do with the LTO 6 FC drive and compatibility with LTT?

 

Does anyone have any suggestions as to how or what we might try to get this test run?

 

thnx so much!
