MSL6000 and Windows Server 2003 communication problems

[ErickSanchez]

Hi Everyone,

I´m having problems with hardware communications between MSL6000 tape drives and my Cell Manager (Wins 2003 x32). I have 2 MSL6000 series as passthru with 8 drives in total. I can discover all drives in Data Protector and in Device manager from Cell Manager, but during a backup the communication is lost with the following message

No cleaning signal of any drive.

Between Cell Manager and MSL6000 exist a HP StorageWorks SAN switch FabricOS 6.1

and then I cannot discover all 8 drives either cell manager and data protector. only 5 drives are discovered

Some idea about this?

thanks in advance

I understand you have 2 MSL6060 stacked with 4 drives installed in each box, right?

You have 2 NSR installed in each box, right?

First connect to the SAN switch and check if all 4 NSR are visible.

Then point the browser to each NSR and check if the are functional.

Find out where is inaccessible drives are and tell.

I did some modification within the NSR configuration in one of four cards, because one of them had "auto asigned" configuration and the another ones was as "indexed", so, now all 4 NSR are as indexed with a mapping as follows:

but now a received errors like:

All drives are connected  properly and all FC cables links well. I did cleaning in all drives and still the problem

any idea about what happens??!!
