MSL6060

[Stijn V]

Hello,

We recently bought an new MSL6060 Tape library, with 4 Ultrium 960 Tape Drives. We will connect this library to the SAN using the "HP StorageWorks Network Storage Router e1200-320 4Gb FC, Embedded" card.

How should I connect the SCSI cables of the drives?

Thanks for your help.

Hi Stijn, check at page 170 on the guide.

hope that help you :)

ATTENTION:

The diagram on page 38 is wrong.
Make sure that you install the terminators on the drive and not on the controller when using LTO3 (960).

Hi, the library was connected as shown on p170. Although on the Unix server I can see only 3 LTO drives instead of 4.

But when using the tool LTT, it shows up 4 tape drives with the following error?

Building Device Map
Checking for redundant devices.

1 drives of library at address 6.0.1[2-50/0/0/10/0/0.1.12.255.0.0.1] could not be found

The latest drive should be -up to me- 17.0.1[2-50/0/0/10/0/0.2.12.255.0.0.2] (logically, because the name includes the switch domain id and port !!)

What I noticed is that there are 4 identical SCSI cables and another type, again 4 identical cables?

Hi Stijn

Maybe This diagram will clarify the right way to connect this specific model, which is an exception of the rule:

http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?lang=en&cc=us&objectID=c00659626&jumpid=reg_R1002_USEN

Otherwise you may experience CRC or Parity Errors as shown in the document.

Assuming you have made the cabling as explained:

First step is to check in the NSR itself if the drive is seen, if it is up or down in the discorery tab.
then second point is to see if you have correctly included this drive in the map for this host

Assuming you have two NSR, and each have two drives, I can exclude a communication problem in the SAN because at least one of the device is seen.

You should pay attention in the OS, to correctly configure the drive (sorry I do not know Unix)

The message you get in LTT indicate that the library know there should be 4 drives on it, because communication is also made internaly of the library, but it indicate this drive is not seen by your OS

Indeed one of the drives was offline, this condition can only happen -up to HP- when a tape is loaded into a drive at the moment that you reboot the library...

I currently powered off the complete library, because all backups (on our older 2 MSL6000) failed after I connected the new library to our SAN (our Unix server which is the Data Protector Cell Manager). Although I used a new isolated zoning for this new MSL6060 ...

We will ask HP to come on site to analyse this issue... thanks for your help anyway!

HP did replace one SCSI cable and terminator (was for LTO2 instead of LTO3)!

Then something was wrong with one SCSI port of an NSR (that's probably the reason why I only saw 3 out of the 4 drives).

But there is still an issue with 2 drives, HP will replace the NSR card again....

Thanks for your help.

I will close this thread.
