Well... the cabling is basically the same or at the very least similar.

Perhaps we should review your current cabling with the NSR first to see if we can resolve those problems...

Can you post a diagram or some additional information about the config?

Info about the NSR... as well as the MDR. Since you have a 5052, can I assume you have 2 NSR's in the back with 1 robotic controller card?

Whats the backup software your customer is using?

Re: cabling msl5052 4 drive to old Compaq MDR

hi..
the cabling is standard cabling for msl5052 with 1 NSR not 2.

Probably i must disconnect the 2 vhdci cable from library to NSR and connect to MDR.
My mdr have 4 port LVD and 2 port HVD (used by old TL891 dismissed).

i try o find cabling schema

thank's

Re: cabling msl5052 4 drive to old Compaq MDR

I would like to understand what issues you hare having with the NSR, since it's a considerably newer router than the MDR (which was discontinued some time ago).

Are you running the latest firmware in the NSR (5.6.69)?

Are you in a supported configuration (listed in the EBS compatability matrix - www.hp.com/go/ebs) and on the latest driver & hba firmware revisions?

Have you disabled windows RSM?
If you are on Windows 2003, have you disabled the plug & play polling?
Have you disabled Insight Manager polling?
Is there anything else in your SAN that could be polling the library/drives?

Do you have any event logs from the NSR we could review?

I've last firmware in all object:
NSR,Library,FCHBA
and last drivers for all server in san.
I don't know how to disable in windows 2003 san polling,but all windows 2000 have RSM disable.
The configuration is supported.
I've attached a log with some error.

Sorry for my english!

Here's the document:

The event log you provided showed a lot of DSA errors, but they were immediately after a write error (SK/ASC/ASCQ = 0x3,0x0C,0x00), and I would therefore ignore those. There is one assertion the next day. I believe there's an assertion trace you can collect that might help. Has this assertion happened before?

Can you also attach or tell us what the Device mappings are? (from the NSR).

Re: cabling msl5052 4 drive to old Compaq MDR

I make a static mapping with library and all host in the san, not auto assign.

Yesterday the library goes off line after another Assertion error, in last months i've a lot of problem and the backup jobs hang.

this is NSR number 3 i've changed but the problem is the same.
HP support have schedule a visit for my customer next week.

Re: cabling msl5052 4 drive to old Compaq MDR

Assertions on NSR are usualy caused by external factors, could you collect a full report, select print view and capture and attach it here, analysis of the traces could help in finding the route cause of the problem
